An Overview of Optimization Approaches for Operation of Hybrid Distributed Energy Systems with Photovoltaic and Diesel Turbine Generator

Humanity is presently confronting a global energy crisis this is due to an insufficiency in traditional energy sources while the energy demands are worldwide increased. In response to this crisis, improving energy efficiency and sustainability and are becoming significantly important. Therefore, distributed energy systems are extremely important in terms of having multiple energy sources to meet time-varying consumer demands. Recently, hybrid distributed energy system has become widely applied to raise system reliability and improve power quality instead of depending on one type of conventional energy sources such as diesel generators. Yet, it faces some challenges in its widespread deployment such as unpredictable nature and intermittently varying renewable energy sources like solar radiation. This issue can be overcome by integrating energy storage that manages the time mismatch between energy production and load requirements. Hence, it is important to review the recent promising approaches for the optimization of hybrid systems to reduce the operation cost and total network losses. This work encompasses a review of the recent optimization approaches for hybrid energy systems with PV, diesel turbine generators, and energy storage systems to give the basis for solving difficult and intricate real-world problems related to distributed energy system operation.
