52	Der Stromausfall in München: Einfluss auf Zahlungsbereitschaften für Versorgungssicherheit und auf die Akzeptanz Erneuerbarer Energien Schubert, Daniel Kurt Josef, Meyer, Thomas, von Selasinsky, Alexander, Schmidt, Adriane, Thuß, Sebastian, Erdmann, Niels, Erndt, Mark 01 October 2013 (has links) Mit dem Forschungsprojekt wurde das Ziel verfolgt, den Einfluss des Münchner Stromausfalls im Winter 2012 auf die Zahlungsbereitschaft für Versorgungssicherheit sowie auf die Akzeptanz für Erneuerbare Energien zu untersuchen. Das Ausfallereignis in München bot sich in besonderer Weise für eine Untersuchung an, da etwa die Hälfte des Stadtgebiets betroffen war, sodass eine Trennung nach beeinträchtigten und nicht-beeinträchtigen Haushalten aus einer nahezu homogenen Stichprobe ermöglicht wurde. Im Zentrum der Untersuchung steht eine repräsentative Bevölkerungsumfrage, die zwei Monate nach dem Ausfallereignis durchgeführt wurde. Dazu wurden über das Telefonlabor der Technischen Universität Dresden 526 Personen aus Münchner Privathaushalten befragt. Nach unseren Befunden beeinflusst eine kleine Versorgungsunterbrechung, wie in München, die Einstellung hinsichtlich der Erneuerbaren Energien nur unwesentlich. Allerdings können wir mit Hilfe der kontingenten Bewertungsmethode einen signifikanten Einfluss des Ausfalls auf die Zahlungsbereitschaft für eine sichere Versorgung nachweisen. Darüber ergeben sich aus unserer Studie Erkenntnisse für die Umsetzung der Energiewende: Beispielsweise wurde der Wert für die letzte gelieferte Kilowattstunde Strom (Value of Lost Load), das Last-Abschaltpotenzial von Haushalten sowie die Akzeptanz der Höhe der EEG-Umlage ermittelt. info:eu-repo/classification/ddc/330 ddc:330
53	ALGORITHM TO DEVELOP A MODEL PROVIDING SECURITY AND SUSTAINABILITY FOR THE U.S. INFRASTRUCTURE BY PROVIDING INCREMENTAL ELECTRICAL RESTORATION AFTER BLACKOUT Casey Allen Shull (7039955) 15 August 2019 (has links) <p>Is North America vulnerable to widespread electrical blackout from natural or man-made disasters? Yes. Are electric utilities and critical infrastructure (CI) operators prepared to maintain CI operations such as, hospitals, sewage lift stations, food, water, police stations etc., after electrical blackout to maintain National security and sustainability? No. Why? Requirements to prioritize electrical restoration to CI do not exist as a requirement or regulation for electrical distribution operators. Thus, the CI operators cannot maintain services to the public without electricity that provides power for the critical services to function. The problem is that electric utilities are not required to develop or deploy a prioritized systematic plan or procedure to decrease the duration of electrical outage, commonly referred to as blackout. The consequence of local blackout to CI can be multi-billion-dollar financial losses and loss of life for a single outage event attributed to the duration of blackout. This study utilized the review of authoritative literature to answer the question: “Can a plan be developed to decrease the duration of electrical outage to critical infrastructure”. The literature revealed that electric utilities are not required to prioritize electrical restoration efforts and do not have plans available to deploy minimizing the duration of blackout to CI. Thus, this study developed a plan and subsequent model using Model Based System Engineering (MBSE) to decrease the duration of blackout by providing incremental electrical service to CI.</p> security sustainability mbse model algorithm approach logic blackout Crisis resiliency reliability infrastructure systems Infrastructure design decisions utility company utility decision maker critical infrastructure protection Critical Infrastructure Resilience National Security disaster relief applications terrorist attacks MBSE SysML electric utility resilient hospitals
54	Community Continuity Management : An Exploration of the Energy Production and Use of a Fictional Stockholm Neighbourhood in a Crisis / Kontinuitetshantering för gemenskaper : Att utforska energiproduktion och användning i ett fiktivt kvarter i Stockholm Brattgård, Nils January 2023 (has links) In an increasingly interconnected, and electricity-reliant world, households are asked to build up their resilience to crises. Local, distributed electricity production within a microgrid with capability to operate disconnected from the larger grid has been shown to be an effective tool for increasing power system resilience in the past. The energy production of local renewable sources is, however, not sufficient in meeting normal household energy demand. This thesis explores whether the forming of communities can be utilised to reduce energy demand and as a result, increase the resiliency of both the community and urban environments. The analysis of household energy use and the subsequently developed toolbox provide insights into energy use both under normal societal function and during a crisis. Through living and cooking together as a community, significant energy-efficiency gains were possible, exceeding those reasonably achieved within each individual household. Community was further determined to be important in the planning and development of more resilient combinations of renewable energy, going beyond solar power. When implemented in theoretical scenarios, energy communities at a building and block level could provide sufficient energy for the households’ most immediate needs without major sacrifices of wellness. The scheme proposed is argued to require not only monetary investments, but also larger societal shifts. Producing sufficient quantities of electricity within urban environments will mean a large change in how cities are experienced. Public understanding and acceptance for such a change is likely to be necessary. Through the implementation, the role of the municipality would go from action-taking to mostly laying the groundwork for the formation of communities, as well as advising these as they achieve higher household resilience. Most critically, however, there is a need for the broader population to embrace working together in communities.
