Because of the fundamental uncertainties inherent in microgrid design and operation, researchers have created battery and microgrid models of varying levels of complexity, depending upon the purpose for which the model will be used.
MGs are a set of decentralized and intelligent energy distribution networks, which possess specific characteristics critical to the evolution of energy systems . There exist several definitions of microgrid in the scientific literature , , , .
Each string has 60 elements. The entire system has a rated capacity of 300 kWh/120VDC (2,500 Ah). The maximum Depth of Discharge (DoD) allowed is 40%. In the Ilha Grande microgrid, the energy storage system was designed to have 24-hours of autonomy and to meet a demand of approximately 130 kWh/day including power inverter losses.
For example, if a battery is replaced when it falls to 80% of original capacity and microgrid operation requires a certain battery capacity, the battery must initially be oversized by 25% to maintain the desired capacity at the end of the battery’s life.
