Stability-Oriented Power Management for Grid-Tied Hybrid Microgrid Using Fuzzy Logic Control

Abstract

A Hybrid Microgrid is characterized by a collection of loads and distributed generation units that function collectively as a singularly manageable entity. As a cohesive energy distribution network, a microgrid possesses the capability to operate either in conjunction with or independently from the primary electrical grid. In the present work PV generating unit (PVU) , wind energy system unit and energy storage unit (ESU) are used for the development of microgrid. The distributed generating (DG) units in microgrid are usually parallel connected which create bus voltage maintenance issues and load sharing among the units. Here fuzzy logic-based control strategy is implemented for power management between source and load with grid-tied operation. The power management strategy manages the power generated from DG, ESU, and Grid and same time control the voltage and frequency of the microgrid the control strategies are verified in the MATLAB/SIMULINK environment.
