The design and optimal sizing of a microgrid consist of determining the nominal capacity of generation systems, configuration, storage capacity, and the operational strategy to maximize reliability and minimize operational cost and pollutant emissions in the life cycle of the project, among other design objectives.
Appropriate sizing of microgrid components, that is, number and size of PV modules, batteries, DGs and associated power electronic devices determines the efficient and economic design of the microgrid. There are numerous sizing approaches available in the literature, which are subjective to the requirements of the microgrid operator.
Nowadays, microgrids (MGs) have received significant attention. In a cost-effective MG, battery energy storage (BES) plays an important role. One of the most important challenges in the MGs is the optimal sizing of the BES that can lead to the MG better performance, more flexible, effective, and efficient than traditional power systems.
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 selection of the most appropriate model depends not only on the accuracy of the solution but also on its computational cost. Depending on the design stage of the microgrid, e.g., sizing, energy management, or stability analyses; different models should be considered.
