Flexible distributed generation: (FDG)

Abstract

Power electronics is the key technology for enabling renewable power generation and dispatching Distributed Generation (DG) with Improved load-side efficiency. This paper proposes a novel control scheme for the nonlinear link connecting DG to the distribution network using a current controlled Voltage Source Inverter (VSI). This link has multi function besides conditioning the power fed from DG system. The proposed system is similar to the FACT devices, but in distribution level. It replaces Distribution STATic COMPensator (DSTATCOM) and Active Power Filters (APF), as it is capable of compensating power quality problems. Reactive power compensation at the point of common coupling PCC is investigated under transmitting the given active power from DG. The effectiveness of the proposed flexible Distributed Generation (FDG) has been verified by simulation.
