Voltage Profile and Stability Analysis of Grid-connected Photovoltaic

Distributed renewable energy has generated significant interest over the last few years with the increasing concern about the global environmental protection. As an alternative source of energy for the future, solar energy is clean, pollution free and inexhaustible. Large scale PV can affect the stability and operation of utility grid. The concern of this book is the impact of PV systems on the behavior of the distribution system. Simulations and analysis were implemented on IDECO grid in this book. The impact of distributed PV system on the power flow and voltage profile of a distribution system has been analyzed while connected to IDECO grid. The impact of different PV generation penetrations on the power flow and voltage profile are compared. Moreover, the impact of the location where PV is installed is investigated. Various test scenarios corresponding to different weather conditions such as solar radiation and temperature are simulated. Sizing and allocation of the PV system in the tested feeder are optimized.
