Impact of photovoltaic integration in the distribution network on time delay of element protections

Abstract

The integration of renewable energy to distribution networks is very increased in those last years, the Algerian government starts in this topic by integration of photovoltaic panels PV to Oued Nechou distribution network. This paper studies the impact of PV integration in Oued Nechou network on line fault time delay. The problem is studied before on IEEE-14 bus network then it is applied on Oued Nechou network. The simulation results are obtained before and after PV integration and are compared. The comparison is done on time delay, power loss and speed of return stable before line fault disappearing. The aim of this study is the evaluation of PV exploitation in Oued Nechou network and the choice of element protections parameters. The networks chosen in this study are modeled and simulated using the PSAT.
