The penetration level of renewable energy sources significantly influences the optimal dispatch strategy of energy storage systems (ESS) in a microgrid. As the proportion of renewable energy (solar, wind) increases, the ESS dispatch strategy needs to adapt to manage the inherent variability and intermittency of these resources. At low renewable penetration, the ESS may primarily be used for peak shaving (reducing peak demand), load leveling (flattening the load profile), and providing backup power during grid outages. The ESS dispatch strategy is relatively simple, charging during off-peak hours and discharging during peak hours or outages. However, at high renewable penetration, the ESS becomes crucial for mitigating the variability of renewable generation, improving grid stability, and maximizing the utilization of renewable energy. The optimal dispatch strategy becomes more complex and needs to consider several factors: 1. Smoothing Renewable Output: The ESS can be used to smooth out the fluctuation....
