This thesis provides heat pump usage in heating mode, heating of potable water or cooling mode. The heat pump is connected with photovoltaic power plant. The main aim of this study is to create photovoltaic system connected with heat pump and present the results of an energetic and economic evaluation. The theoretical part describes principle function heat pumps, photovoltaic power plants and components. The study provides as well a description of heating systems with a heat pump used for space heating or cooling. In the practical part of this thesis was performed calculation of energy consumption in a building. Based on this data, has been selected a suitable heat pump. To reduce the energy consumption was designed a hybrid photovoltaic power plant with a battery accumulation. Utilization of electric energy from photovoltaic system was calculated. Solutions provide the option of the energy flow analysis in specific interval. Results are summarized in the energetic and economic evaluation. The proposed solution can be applied for reconstruction or construction of a new building, focused on usage of renewable resources and emissions reduction.

The Master´s thesis deals with issues of operational performance of two photovoltaic power plants. In the thesis is stated the history of photovoltaics, description of photovoltaic effect, used materials and production technology of the most used material in PV industry – Silicon. The basic parts and parameters of photovoltaic power plant are described. Thesis also solves, how could be done the first and periodically control due to relevant directives. The ways of diagnostics potentional failures, methods of measuring and the exam of monitoring system are stated. Practice part is focused on measuring and comparing operational performance of FVE Kurdějov and FVE Šakvice II. Operational performance was calculated from exported data for years 2014 and 2015. The thesis also contains measuring of each string connected to inventors, which are installed on the power plant. The result is an identification of strings with decreased operational performance. Based on that was created recommendations for optimalization and increase of the performance. The last part is software for simulation of photovoltaic power plant. This SW calculates potentional energy, which could be produced in a day with available data export. The calculation is defined by parameters, which are assigned.

The master thesis The Influence of Photovoltaic Power Plants Disconnection During Frequency Deviations introduce reader to the theory of frequency regulation in the electric power system. The theoretical part introduces regulation reserve that are used by transmission system operator to balance power imbalances. In the next part is made introduction to the system state classification and knowledge of European Network of Transmission System Operators for Electricity about unsolicited disconnection of photovoltaic plants. The theoretical part of the recommendations and simulations is followed by a part of the work in which the analysis of the implementation of the frequency boundary in which the photovoltaic power plants are operated in selected states of synchronously interconnected Europe. The master thesis continues to explain the origin of power imbalances by introducing a theory of electricity trading. Deterministic frequency deviations are one of the causes of the occurrence of frequent imbalances in the system and are discussed in the following chapter together with a proposal for a possible solution. In the last part of the master thesis are presented simulations that were made to determine the impact of the speed control regulator in the Czech Republic on unsolicited disconnection of photovoltaic power plants.

This master´s project deals with design of an office building nearly zero energy standard. My master´s project consists of three parts. In the first one I work on technical design of the office building. It is a three-storey building with partial basement. Vertical load-bearing system is partially made from monolithic concrete walls and partially from clay blocks walls. The horizontal load-bearing structures are made of monolithic concrete slab. All roofs are designed as flat roofs. In second part I design all technical equipment in this building. In the last part I compare three types of roof, photovoltaic power plants and evaluate their environmental impact. First type of PV power plant is made by monocrystalline solar cell, second one by polycrystalline solar cell and last one by monocrystalline solar cell with battery system. Environmental impact of these systems is evaluated in Open LCA software. All structures comply with the valid standards and regulations.

The diploma thesis on „Optimizing of shopping center energy demands“ deals with the reduce of the energy demand of the shopping center. The theoretical part describes the possibilities of reducing the energy intensity in terms of renewable resources, the potential of renewable resources. In practical part the energy audit of the existing building is designed, then the possibilities of reducing the energy intensity of the building, the budget and expressed return on investment by means of the net present value, the internal rate of return and simple payback period.

Main purpose of the thesis is to create proposal of the photovoltaic hybrid system for commercial building in accordance with applicable rules for energy savings program. The introductory part of the thesis describes the rules regarding the photovoltaic system parts. The next part of the thesis describes the available technical solution for realization of the photovoltaic system design and the possibilities of electric energy accumulation in these systems and how to deal with power overflows using the power flow controller and what is the negative impacts on the distribution network when switching the connected load. In the next part the design of the PV system is carried out according to the valid assumptions described in the theoretical part of the thesis. Verification of power flow controller and measurement results in UEEN laboratories. The last part of the thesis is an evaluation of the economic part of the proposed system.

This master’s thesis engages in project of outgoing transformer unit for the photovoltaic power station. It describes project and its design documentation what conducts to practising of construction. It has compared investing to more expansive transformer what has lower loss. It describes charges of operation’s transformer in twenty years. It leads project of cable low voltage. It compares whether is better to use aluminium or cupric cables. Project is led with respect for investment costs and minimum of operation loss.
