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...
Recently, the number of distributed generation (DG) that connects to a distribution system has been increasing because of reduction of the environment load. However, the harmonic troubles in a distribution system are apprehended accompanying the increase of connection of DGs through the power conditioner system (PCS) (i.e. interconnected inverter of DG) and the spread of the power electronics equipments...
This paper presents three models for dynamic analysis of inverter-based distributed generators equipped with voltage positive-feedback anti-islanding protection. The models analyzed are: the switched model, where the switches are represented in details, the average model, where the switches and signal generators are replaced by controlled voltage sources, and the small-signal model, where the average...
