The world's energy supply today mainly consists of fossil fuels and nuclear power. Moving away from the use of these energy resources to renewable energy sources is considered a prerequisite for a sustainable future. In order to implement this change, it is necessary for renewable energy sources to be environmentally, technically and economically sustainable. A major challenge encountered in terms of technological sustainability is the intermittent nature of renewable energy sources. As the share of renewable electricity increases in the system, the electricity grid is facing new challenges such as increased instability of the frequency and capacity shortages. In order to meet these new challenges an increased flexibility from electricity users is proposed as a solution. Flexibility can be achieved either by controlling the use of electricity or utilizing energy storages. If different electric loads are to be controlled in a property, data regarding the power use of the loads must first be collected with a high time resolution in order to be able to properly analyze the data. Measures to shift or reduce the power peaks in a property can then be suggested and implemented. A battery storage can help reduce power peaks or shift loads in time and if done on a large scale that would reduce the strain on the entire Swedish grid. One of the ancillary services that the battery could offer is frequency regulation. Using energy storages for such an application could also provide a secondary revenue stream, aside from the revenue stream from peak shaving, and increase the profitability of the storage. Sweden has seen a dramatic increase in electric vehicles over the last decade and charging of the vehicles has become an issue for many property owners as it often creates power peaks. The data collection regarding power use in properties performed in during this thesis showed that valuable data can be collected with the method and material used. With a battery price of 3000 SEK/kWh the payback time for a battery system can be reduced from 17,9 to 7,8 years if it is used for frequency regulation during the night. If power-intensive loads such as electric vehicle charging are added to the model the payback period decreases to 6,1 years. With these results in mind, it can be concluded that the profitability of a battery storage can increase to the extent that the investment is of economic viability. In addition, the investment helps to improve the stability of the Swedish grid. The results are found to be relatively consistent with those of other similar studies. / <p>Digital presentation</p>

Morgongåva is an urban centre in Sweden, with several challenges in the electrical power grid. In order to use the power grid more efficiently, this report investigates potentials of installing a battery energy storage system (BESS). Focus lies on finding economic and technical benefits of reducing power peaks, which occur during high demand hours when transmitting energy is more expensive. This method is referred to as peak shaving. Further, economic calculations if installing a BESS are based on electricity pricing data. Calculations regarding technical benefits are based on net power demand data. Further, the study shows that the usage of the grid, which was measured with the load factor, would increase and thus allow installation of more power sources and connecting more load to the grid. The load factor was estimated to increase by an average of 2.12 percent each month in 2019. In one year, the economic profit was estimated to be 91,000 kr. The conclusion is that there are economic profits for Sala-Heby Energi of installing a BESS, but more importantly a BESS has technical consequences in the power grid. Where technical benefits are important in order to reach the goals of Agenda 2030 but also to obtain a more reliable grid for the customers. A sensitivity analysis shows that the model is robust. Thus, the conclusion is that Sala-Heby Energi and the local electricity grid in Morgongåva would benefit from installing a BESS.

abstract: In this work, the stacked values of battery energy storage systems (BESSs) of various power and energy capacities are evaluated as they provide multiple services such as peak shaving, frequency regulation, and reserve support in an ‘Arizona-based test system’ - a simplified, representative model of Salt River Project’s (SRP) system developed using the resource stack information shared by SRP. This has been achieved by developing a mixed-integer linear programming (MILP) based optimization model that captures the operation of BESS in the Arizona-based test system. The model formulation does not include any BESS cost as the objective is to estimate the net savings in total system operation cost after a BESS is deployed in the system. The optimization model has been formulated in such a way that the savings due to the provision of a single service, either peak shaving or frequency regulation or spinning reserve support, by the BESS, can be determined independently. The model also allows calculation of combined savings due to all the services rendered by the BESS. The results of this research suggest that the savings obtained with a BESS providing multiple services are significantly higher than the same capacity BESS delivering a single service in isolation. It is also observed that the marginal contribution of BESS reduces with increasing BESS energy capacity, a result consistent with the law of diminishing returns. Further, small changes in the simulation environment, such as factoring in generator forced outage rates or projection of future solar penetration, can lead to changes as high as 10% in the calculated stacked value. / Dissertation/Thesis / Masters Thesis Electrical Engineering 2020

abstract: In recent years, many school districts, community colleges, and universities in California have implemented energy management-as-a-service (EMaaS). The purpose of this study was to analyzes how EMaaS has been realized in California schools, including how performance expectations and service guarantees have been met, how value is created and captured, and which trends are emerging in the pay-for-performance models. This study used a qualitative research design to identify patterns in the collected data and allow theories to be drawn from the emergent categories and themes. Ten in-depth interviews were conducted with a diverse pool of facility managers, energy practitioners, superintendents, and associate superintendents working with EMaaS. Four themes emerged (1) peak shaving overperformance, (2) low risk/reward, (3) performance exactly as expected, and (4) hope in future flexibility. This study reveals medium to high levels of performance satisfaction from the customers of cloud-enabled and battery-based EMaaS in California schools. Value has been captured primarily through peak shaving and intelligent bill management. Large campuses with higher peaks are especially good at delivering energy savings, and in some instances without pairing batteries and solar. Where demand response participation is permitted by the utility companies, the quality of demand response performance is mixed, with performance being exactly as expected to slightly less than expected. The EMaaS business model is positioned to help California schools implement and achieve many of their future sustainability goals in a cost-effective way. / Dissertation/Thesis / Masters Thesis Construction Management 2020

Battery Storage Systems (BESS) installed Behind the Meter (BTM) can provide demand management services, reducing electricity costs and enhancing overall electricity system stability. BTM BESS can also imporve self-consumption obtained with distributed generation assets like solar photovoltaics. This study examines the influence on value creation from consumption patterns and utility tariffs. Using Swedish and UK tariffs and a set of consumption profiles, the study determines the optimal BESS configuration and conducts simulations to assess profability through Net Present Value. Comparative analysis reveals the impact of utility tariffs and consumption profiles on profitablility. Projected BESS cost levels for 2030 and 2050 are used to evaluate expected future profitability.  The findings indicate that utility tariff has a stronger influence on BTM BESS profitability than consumption profile. Energy arbitrage creates most of the value, depending more on tariff structure than consumption pattern. However, with higher demand charges, the consumtion profile becomes more important as the relative value of peak shaving increases. Two sensitivity analyses have been performed. The first shows that NPVs are affected by decreased electricity price variability, emphasising the need for accurate long-term price forcasts. The second shows that existing electricity consumption forecasting techniques prove sufficient for effective peak shaving.  In conclusion, this research inderscores the significance of utility tariffs and consumption profiles in determining BTM BESS profitability. Energy arbitrage dominates value creation, while peak shaving gains importance with higher demand charges. Accurate long-term price forecasts are crucial for assessing BTM BESS profitability, and existing consumption forecasting techniques are suitable for peak shaving. / Batterilagring installerad bakom elmätaren kan optimera en fastighets elkonsumtion för att reducera elkostnader samt förbättra stabiliteten i elsystemet som helhet. Den här studien undersöker faktorer som påverkar värdeskapande genom energiarbitrage och peak shaving, inklusive konsumtionsprofiler och eltariffer. Studien undersöker även om det går att uppnål önsamhet under nuvarande och framtida prisnivåer för batterilagring. Studien utgår ifrån svenska och brittiska eltariffer samt fem konsumtionsprofiler, och fastställer den mest optimala konfigurationen av batterilagring genom optimering. Därefter jämförs lönsamheten genom nettonuvärde-analys för att dra slutsatser om hur eltariff och konsumtionsprofil påverkar lönsamhet. Studien visar att lönsamhet för batterilagring bakom mätaren beror mer på eltariff än konsumtionsprofil. Detta eftersom mest värde skapas genom energiarbitrage som är mindre beroende av konsumtionsprofil men direkt beroende av variationer i elpriset. Med högre effektavgifter ökar lönsamhetens beroende av konsumtionsprofilen då det relativa värdet av peak shaving höjs. En känslighetsanalys visar på en stark korrelation mellan värdet av energiarbitrage och variationer i elpriset, vilket visar vikten av långsiktiga prognoser av elprisets volatilitet. Befintliga tekniker för prognostisering av elkonsumtion har tillräcklig noggrannhet för effektivpeak shaving. Sammanfattningsvis visar studien hur eltariff och konsumtionsprofil påverkar lönsamheten för batterilagring installerad bakom elmätaren. Majoriteten av värdet skapas genom energiarbitrage för svenska och brittiska tariffer. Med högre effektavgifter ökar betydelsen av peak shaving. Dessutom betonar studien vikten av långsiktiga prognoser av elprisvolatilitet vid utvärderingen av lönsamheten för investeringar i batterilagring bakom mätaren.

In this report the problem of constructing a bus depot with electrical buses despite the lack of grid capacity, was analyzed. A potential solution is investigated, namely smart control of heat pumps in industries. The possibility of allocating grid capacity to the bus depot by reducing power consumption in heat pumps during peak hours, is taken into consideration. The maximum amount of released capacity in an industrial area is calculated through the controlling of heat pumps. This investigation was made through simulations with a simplified building energy model (lumped capacity model) which was applied to a reference building. After mapping the area Boländerna and the geothermal wells located there, IKEA Uppsala was chosen as the reference building, since a third of the total number of wells were found in that area. To take the whole capacity of Boländerna into account, the model was scaled up to estimate the total, possible reduction of power. The bus depot requires 6 MW nighttime and 4 MW daytime, the total amount of electrical power that could be withdrawn, if all heat pumps were on maximum heat, in the chosen area were 0.75 MW and by controlling the heat pumps during an optimized level, the amount of 142 kW could be made available to the electric grid. 142 kW is not enough cover the need for the bus depot but it could supply the need for a slow charger to one of the buses and is therefore a possible sub-solution to the larger problem.

Pois, devido a diversos fatores, acaba por aumentar as chances do desenvolvimento de afecções respiratórias e a qualidade do material utilizado como cama é fator agravante. Diante disto, três grupos com 5 equinos cada foram submetidos a 45 dias sob o mesmo manejo, sendo dois grupos estabulados com diferentes tipos de cama, um com maravalha esterilizada (ME) e o outro com maravalha não esterilizada (MNE), e o terceiro grupo a pasto (Pasto). Foram realizadas análises do lavado broncoalveolar (LBA) (celularidade e marcadores de estresse oxidativo) e hemograma antes do início do manejo (Basal) e posteriormente a cada 15 dias (M15, M30 e M45). Também foi avaliada a presença de gêneros fúngicos nas amostras de cama, e do feno utilizado na alimentação dos animais. Os hemogramas permaneceram dentro dos valores da normalidade. Os valores obtidos de malondialdeído (MDA) e ácido úrico no LBA não apresentaram diferença entre os momentos e grupos avaliados. A vitamina C no LBA apresentou queda em seus valores em M30. Os três grupos apresentaram queda nas concentrações de glutationa reduzida em M30, tendo havido diferença significativas entre os grupos Pasto e MNE. Os grupos ME e MNE apresentaram queda nos valores de glutationa oxidada em M45, já o grupo Pasto apresentou queda constante a partir de M15, com diferença significativa em relação ao grupo ME em M30. A superóxido dismutase apresentou aumento em M30 no grupo MNE, levando a diferença significativa em relação aos grupos Pasto e ME. A glutationa peroxidase no LBA apresentou queda significativa no grupo ME em M45. Quanto a celularidade do LBA a contagem de células nucleadas totais e eosinófilos não apresentaram diferenças significativas. O grupo ME apresentou elevação nos valores de neutrófilos em M30, levando a diferença significativa em relação aos grupos MNE e Pasto, já o grupo MNE apresentou queda significativa em M45. Os grupos ME e MNE apresentaram queda nos valores de linfócitos no LBA em M30, já o grupo Pasto apresentou queda em M15. O grupo Pasto apresentou aumento dos macrófagos no LBA em M15 e M30. As análises das amostras de cama e feno apresentaram baixas porcentagens de gêneros fúngicos. Grande parte das alterações apresentadas ocorreram em M30, momento em que foram registradas as menores temperaturas e maiores velocidades dos ventos durante todo período experimental, o que possivelmente levou a um desequilíbrio oxidativo pontual, com pequenas variações na celularidade do LBA. Acredita-se que o manejo, as boas condições de higiene e ventilação das baias tenham contribuído para que não houvesse o desenvolvimento de alterações inflamatórias no sistema respiratório dos animais avaliados. Deste modo, podemos concluir que não houve diferenças significativas na manutenção dos animais nos diferentes tipos de cama em relação a resposta inflamatória, estresse oxidativo e desenvolvimento fúngico. / The great challenge of the respiratory defense system is the maintenance of animals in stalls, which due to several factors ends up increasing the chances of development of respiratory diseases. The quality of the material used as bed is an aggravating factor. Three groups of 5 horses were submitted to 45 days under the same management, and two groups were housed with different types of beds, one with sterilized wood shaving (ME) and the other with unsterilized wood shaving (MNE), and the third group was maintened in the pasture. Bronchoalveolar lavage fluid (BALF) and hemoglobin analyzes were performed before baseline and then every 15 days (M15, M30 and M45). It was also evaluated the possible presence of fungal genera in bed samples, and in hay used in animal feeding. The hemograms remained within normal values. The values of malondialdehyde (MDA) and uric acid in BALF showed no difference between the moments and groups evaluated. Vitamin C in BALF showed a decrease in M30 values. The three groups showed a decrease in the concentrations of glutathione reduced in M30, and there were significant differences between the groups pasture and MNE. The ME and MNE groups showed a decrease in the values of oxidized glutathione in M45, whereas the pasture group presented a constant drop from M15, with a significant difference in relation to the ME group in M30. Superoxide dismutase increased in M30 in the MNE group, leading to a significant difference in relation to the pasture and ME groups. Glutathione peroxidase in BALF showed a significant decrease in the ME group in M45. As for the cellularity of BALF, total nucleated and eosinophil counts did not showed significant differences. The ME group presented elevation in neutrophil values in M30, leading to a significant difference in relation to the MNE and pasture groups, whereas the MNE group presented a significant decrease in M45. The ME and MNE groups presented a decrease in lymphocyte values in the BALF in M30, whereas the pasture group presented a decrease in M15. The pasture group presented increase of the macrophages in the BALF in M15 and M30. Bed and hay samples showed low percentages of fungal genera. Most of the alterations presented occurred in M30, at which time the lowest temperatures were recorded throughout the experimental period, possibly leading to a punctual oxidative imbalance, with small variations in BALF cellularity. It is believed that management, good conditions of hygiene and ventilation of the boxes contributed to the no development of inflammatory changes in the respiratory system of the animals evaluated. Thus, we can conclude that there were no significant differences in the maintenance of the animals in the different types of bed in relation to the inflammatory response, oxidative stress and fungal development.

Diesel engines operating the rig pose the problems of low efficiency and large amount of emissions. In addition the rig power requirements vary a lot with time and ongoing operation. Therefore it is in the best interest of operators to research on alternate drilling energy sources which can make entire drilling process economic and environmentally friendly. One of the major ways to reduce the footprint of drilling operations is to provide more efficient power sources for drilling operations. There are various sources of alternate energy storage/reuse. A quantitative comparison of physical size and economics shows that rigs powered by the electrical grid can provide lower cost operations, emit fewer emissions, are quieter, and have a smaller surface footprint than conventional diesel powered drilling. This thesis describes a study to evaluate the feasibility of adopting technology to reduce the size of the power generating equipment on drilling rigs and to provide ?peak shaving? energy through the new energy generating and energy storage devices such as flywheels. An energy audit was conducted on a new generation light weight Huisman LOC 250 rig drilling in South Texas to gather comprehensive time stamped drilling data. A study of emissions while drilling operation was also conducted during the audit. The data was analyzed using MATLAB and compared to a theoretical energy audit. The study showed that it is possible to remove peaks of rig power requirement by a flywheel kinetic energy recovery and storage (KERS) system and that linking to the electrical grid would supply sufficient power to operate the rig normally. Both the link to the grid and the KERS system would fit within a standard ISO container. A cost benefit analysis of the containerized system to transfer grid power to a rig, coupled with the KERS indicated that such a design had the potential to save more than $10,000 per week of drilling operations with significantly lower emissions, quieter operation, and smaller size well pad.

Energy storage systems is very useful to use in solar panel systems to save money, but also tobe more environment-friendly. The project was given by the solar energy companyPerpetuum Automobile (PPAM) and the project is for their customer, the condominiumcompound Ekoxen. The task is to make a energy regulation for Ekoxen's energy storage sothey can save more money. The energy storage primary task is to shave the top-peaks of theconsumption for Ekoxen. Which means that the battery will supply the household instead forthe three-phase grid. This will make the electric bill for Ekoxen cheaper. Thesimulation/analysis of the energy regulation is done in a spreadsheet tool, where one partworks as a Time-of-Use program and the other work as a modbus feature. Time-of-Use is aweb-based program for PV systems with battery storage, where time-periods can be set toaffect the battery behavior. The modbus feature simulates a system where an algorithm can beimplemented. The results will show that the time-periods for charging the battery with theTime-of-Use program needs to be changed two times per year. One time for the summermonths and a second time for the rest of the months. The results will also show that themodbus feature is better on peak shaving than the time-of-use program.
