Energy Management of an Off-Grid and Grid Connected Hybrid Renewable Energy Source Micro-Grid System for Commercial Load

Microgrids are making inroads into the commercial market, due to advancements in technologies and lower costs. They are used to increase the reliability and resilience of electricity networks. Additionally, they are capable of incorporating dispersed sustainable energy resources such as solar photo - voltaic (PV) generation and wind energy. Energy independence, financial returns, and sustainable energy inclusion are the three main considerations pushing microgrid development and deployment in regions with existing electrical grid infrastructure. In terms of technical feasibility and cost, the right combination of generation units and storage devices will result in the best system design. The goal of this research is to optimise Hybrid Renewable Energy Source-Micro Grid (HRES-MG) sizing for a commercial organisation in Off-Grid, Grid Connected (GC), and Blackout modes based on a techno-economic study performed using HOMER PRO software. Real-time energy management studies on the proposed HRE-MG system are performed in Typhoon HIL software and the results are presented. Solar Photovoltaic (PV), Wind Turbine (WT), Diesel Generator (DG), and Battery Bank (BB) are the generation and storage resources in the MG under investigation. The techno-economic advantages of HRES for the location are explored.
