Standalone hybrid energy system model and control for economic load dispatch

Abstract

It is very expensive to connect remote areas to the grid. For reliable and sustainable electricity supply in remote areas, renewable energy sources are commonly used as supply options. Wind and solar energy are the most sustainable renewable energy resources because of their good compensation characters when combined into a hybrid energy system. This paper presents a case study of a hybrid energy system for a remote rural location. The hybrid energy system consists of a solar photovoltaic system, wind energy system, battery bank storage system and a diesel generator. The diesel generator is used for backup power supply. Results show that the proposed hybrid energy system performs better than the diesel generator acting alone. The economic saving is more than 50% when the proposed hybrid energy system is used.
