The hybrid microgrid consists of networked diesel generators, PV panels, and battery storage. To calculate the expected performance of the backup system for a given outage, we first determine the initial probabilities of being in each system state, which is dependent on the number of working generators and the battery initial state of charge (SOC).
The battery achieves significant revenue from the frequency regulation market. The breakdown of wholesale revenue is about 60% from frequency regulation, 39% from energy, and less than 1% from spinning reserve. The demand response revenue is reduced compared to the diesel-only microgrid because of the reduced EDGs.
