Voltage Source Converter with Different Control Strategies for a MicroGrid-connected Solar PV with Nonlinear Loads for Current Harmonics Compensation

The current advancements and research in power generation are concentrating more on PV generation. In practical, the nonlinear loads create more power quality issues, which encourage many researchers to concentrate more on power quality-related issues. This paper mainly concentrates on the design of voltage source converter (VSC) which acts as an active power filter (APF) for compensating the currents to reduce power quality issues like current distortions in non-linear loads. Different control strategies like conventional and fuzzy controllers are implemented for the control of voltage source converter. The grid is connected to a non-linear load for analysing the grid parameters with different control strategies. Instantaneous power theory modified and is applied for the current compensation which performs effective performance in controlling the VSC.
