Performance Assessment of Power Quality on a Sustainable Design of a Photovoltaic System for a Local Area

This research paper presents the simulation model of a Grid connected photovoltaic system to supply electric power to meet the energy demand of 31 MW by a local community. The power systems consist of a Generator of 250 MVA and an inverter of 2 MW. The 2 MW PV array serves a 1 MW local load and the surplus is delivered to the distribution line of 14 km which has a load of 30 MW connected to it. In the first iteration of time, PV power goes from 100% to 50 % and back up to 100 % for 60 seconds of operation (ramp rate of 100 kW per second). A three-phase line- to- ground fault occurs on the substation point of the 14 km feeder. The fault is cleared after 6 electrical cycles. The simulation of the distribution system is performed in MATLAB/Simulink in order to investigate if it meets the IEEE-1547 standard.
