The world energy requirement has skyrocketed radically in the past two decades raising concern over energy security and adequacy. Energy resource planning plays a substantial role in the global economy and geopolitics of clean energy to achieve global commitment towards sustainable development. It includes strategic management, control and storage of energy supply. Microgrids contribute another layer to the apparent advantages of renewables by boosting system performance and mitigating energy losses. The prospects of energy resource management with the benefits of a hybrid microgrid are discussed here with a brief review of past research works on challenges encountered in voltage and frequency regulations with low-inertia issues, demand response, renewable system integration with transition conditions, and tuning controllers with metaheuristic optimisation techniques.
