摘要

Future society entails new paradigms in how the world will work; new ideas as Smart Grid, Smart Cities, Smart Homes, and their interactions have been established and studied. With the inclusion of Information and Communication Technology (ICT) components into the low-voltage (LV) distribution grid, some measurement signals from smart meters are available for distribution network control with high penetration of photovoltaic systems (PV). This paper takes a local voltage-control strategy for smart LV distribution networks, by using a fuzzy based methodology using local information collected from smart meters as status information source of the grid. Comparative studies are presented for a smart home LV distribution system to validate the method, showing the robustness of proposed method compared with the traditional local approaches. To illustrate the applicability of the proposed method, a real-time digital simulator for smart distribution power grids with a the developed voltage-control system are used. The results show the proposed method can simultaneously mitigate the PV reactive power injection, as well as minimize the voltage rise and power losses.
