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).
In a standalone microgrid system, prolonging the life of the equipment is necessary to reduce the cost of its replacement. However, the size and installation costs of the storage systems must be appropriate. Therefore, this paper provides an appropriate weighting to minimize the cost of the microgrid system.
