PV generation and its impact on low voltage network

Abstract

The objective of the paper is to present the modelling of the single phase grid connected Photovoltaic (PV) generation and its impact on low voltage grid. The network model has been developed in PSCAD software. The designed system includes low voltage network, single phase voltage source inverter (VSI) to control active (P) and reactive power (Q) flow to the grid and PV panel as the main source of energy. In order to control PV active power output and maintain the reactive power to zero value, a typical control scheme (PQ control) has been used. The impact of the PV generation on the network voltage is assessed and analyzed.
