Abstract

Distributed energy resources (DER) are relatively small-scale generators or energy storage units that are located in close proximity to load centers. The DERs that are integrated to the grid with the power electronic converter interfaces are capable of providing nonactive power in addition to active power. Hence, they are capable of regulating the voltages of weak electrical buses in distribution systems. This paper discusses voltage control capability of photovoltaic (PV) systems as compared to the traditional capacitor banks. The simulation results prove the effectiveness of dynamic voltage control capability of inverter-based PVs. With proper control algorithms, active and nonactive power supplied from DERs (e.g., solar PVs or micro-turbines) can be controlled independently. This paper also presents the scenario of controlling active and nonactive power supplied from a PV array to track and supply the local load.
