Integration of PV based DG Source in AC Microgrid with Interconnection to Grid

摘要

Objectives: This aim of the paper is to achieve most edges from the grid-interfacing inverters, implementing in threephase four-wire distribution systems. Statistical Analysis: The work is carried out using MATLAB/SIMULINK software. This work overcomes the power quality problems by including grid interface inverter control. Findings: The grid for three phase four wire distribution is integrated with photo voltaic system which is a renewable energy supplier. Electrical converter is made to perform as multifunction device by introducing active power filter. So this is a novel approach in which inverter can be utilized as: Power converter to injecting power to the grid, and it compensates current unbalance, harmonic current, and load neutral current through shunt Active Power Filter. To improve the performance of the system when highly nonlinear loads are present all of these functions can be accomplished at the same time or individually. Application/Improvements: This work is used in power system applications.
