This paper is aimed to model the electrical transmission grid of Germany accessing future of electricity generation targeting year 2023. For the need of alternating current, while shutting down nuclear power plants and reduction of emission of green house gases, renewable energy comes into picture. With the data from German Network Regulatory Body (BNA), the high voltage transmission grid of Germany...
In an effort to better understand the impacts of high penetrations of photovoltaic (PV) generators on distribution systems, Arizona Public Service and its partners completed a multi-year project to develop the tools and knowledge base needed to safely and reliably integrate high penetrations of utility- and residential-scale PV. Building upon the APS Community Power Project-Flagstaff Pilot, this project...
Based upon the analysis of the mechanism of power loss and voltage drop in distribution system, a new automatic control method of reactive compensation, namely, Feeder Power Factor Assessment (FPFA) is proposed in this paper. Promising that the voltage of all nodes is qualified, the proposed method aims at keeping the power factor of feeders between 0.98 and 1.0 in lagging, so that the reactive power...
