Customer ServiceSome factors that influence the cost of a BESS in Microgrid Mode are system size, energy capacity, and installation requirements. However, it guarantees long-term savings in various ways: reduced energy costs and increased reliability.

Customer ServiceThe California site has the largest sizing of PV and battery due to significant value from retail bill savings, demand response, and wholesale markets. The value achieved by the addition of PV and battery is large enough to offset the added cost of the microgrid, and this is the only site to have a positive net present value.
The probability the BESS stops functioning at a level necessary to support a microgrid that is islanded for less than 2 weeks is very small. The anticipated battery degradation rates for systems is inconsequential over a two-week period and can be ignored.
The control system for the smaller microgrid will likely cost less in real dollars but consume more of the overall project budget than the control system for the larger one. “Your control system may be a little less [costly] in smaller ones, but it’s going to be a much larger portion of the cost than in the larger one.
Initial system state and generator failure The performance of a microgrid system during an outage depends on the system configuration, when the outage occurs, and the outage duration. The system configuration is determined by the size and number of EDGs, along with the PV and battery sizes.
For all scenarios discussed in this paper, the load and PV power inputs are eighteen days of actual 1-min resolution data from an existing microgrid system on an island in Southeast Asia, though any load profile can be used in ESM. The load has an average power of 81 kW, a maximum of 160 kW, and a minimum of 41 kW.
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.
