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.
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.
The main difficulty around battery grid forming is that the state of charge of batteries is always a challenge to measure accurately. The ability to ascertain and accurately measure the charging level of your battery is a basic requirement for the correct operation of the whole system.
Not only that, but it is also critical for the maximum battery endurance, otherwise, the batteries will have to be replaced at a comparatively early stage. In the case of microgrids, it is also imperative that only one energy source can be grid forming. This means that this component sets the voltage and frequency of the whole grid.
A Microgrid controller such as the ePowerControl MC (Microgrid Controller) controls and monitors the charging and discharging of the Battery Energy Storage Systems. It prevents the system from overcharging and also protects against deep discharging. Microgrid controllers specify a predefined maximum voltage and a final discharge voltage.
