Voltage and Reactive Power Regulation With Synchronverter-Based Control of PV-STATCOM

This paper presents a synchronverter based photovoltaic (PV) system as STATCOM (PV-STATCOM), in which inverter exchanges active and reactive power with the grid. The proposed provides compensation during daytime well nighttime. Additional operating modes for PV-STATCOM are to enhance its capability. controller is compared conventional control on basis of performance different tests. key difference between that emulates inertia frequency voltage system. It observed reduces deviation satisfactory regulation point common coupling (PCC) full mode partial mode. low ride through (LVRT) test also performed In weak grid situation, performs more stable manner than both PCC study EMTDC/PSCAD simulation software. Real Time Control Hardware Loop (CHIL) Digital Simulator (RTDS) microcontroller validate strategy design.
