Objective

The main objective of this project is to enhance the reliability and accessibility of electricity in remote areas by using multiple parallel photovoltaic inverters based microgrid.

Abstract

In this project, a self-adaptive control strategy is presented for a microgrid for ensuring a seamless transition between the islanded mode (IAM) and grid connected mode (GCM) of operation with a proportional power sharing. This microgrid consists of two solar PV inverters based on local distributed generation (DG) units. Each PV inverter unit feeds an active power to support local loads and power demand of each local load is shared between respective DG units and microgrid. The PV-battery interfaced main unit with a self-adaptive control strategy in parallel with a PV array supported unit-2 is considered to operate in IAM and GCM of operation. The control strategy achieves transient free operation during load disturbances, power variation at PV array side and off grid operation. Moreover, the microgrid ensures high-quality performance at PCC (Point of Common Coupling) and provides the seamless transition between GCM and IAM to guarantee a continuous power to critical loads. The simulation results can be evaluated by using Matlab/Simulink Software.
