Fuzzy logic-based energy management system of stand-alone renewable energy system for a remote area power system

ABSTRACT

Renewable energy systems (RES) are being widely accepted as an alternative to standard conventional energy sources due to depletion of natural resources and their consequential environmental impact. One of the increasing uses of stand-alone RES is in powering the remote areas where grid power is significantly expensive due to transportation. However, the energy management of such systems is quite complex. This paper deals with fuzzy logic-based controller design for power management of a stand-alone hybrid renewable energy systems (HRES). The proposed intelligent energy management aims to minimise the operation cost and the environmental impact of a microgrid while significantly improving the economic and technical performance of power supply. The proposed fuzzy logic controller (FLC) ensures the power management between renewable energy generation, energy storage, and load. The simulation results clearly show that the controller demonstrated high performance under various load and generation conditions.
