Impact of Grid Connected Photovoltaic System on Total Harmonics Distortion (THD) of Low Voltage Distribution Network: A Case Study

2018 Twentieth International Middle East Power Systems Conference (MEPCON), 2018
Integrating renewable energy resources especially photovoltaic systems with microgrids has become an unavoidable choice for most countries and in Egypt the government has this ambition to reach a percentage of 20% of the total national electricity generation from solar energy. Which in turn bring some challenge to the electrical utility operator.
