Techno-Economic Evaluation of Optimal Integration of PV Based DG with DSTATCOM Functionality with Solar Irradiance and Loading Variations

Nowadays, the trend of countries and their electrical sectors moves towards inclusion renewable distributed generators (RDGs) to diminish use fossil fuel based DGs. The solar photovoltaic-based DG (PV-DG) is widely used as a clean sustainable energy resource. Determining best placements ratings PV-DG significant task for systems assess potentials. With capability inverters inject required reactive power in system during night period or cloudy weather adds static compensation (STATCOM) functionality PV unit, which being known compensator (DSTATCOM). In literature, there research gap relating optimal allocation PV-DGs along with seasonal variation irradiance. Therefore, aim this paper determine sizing injected by inverters. An efficient optimization technique called Gorilla troop’s optimizer (GTO) solve problem DSTATCOM on 94 bus distribution network. Three objective functions are multi-objective function, including total annual cost, voltage deviations, stability. simulation results show that integration superiorities reducing cost considerably enhancing performance voltages deviations stability compared without functionality. can reduce 15.05% 77.05%, respectively. While enhanced 25.43% base case.
