A possible method for building the knowledge base is to use different techniques such as genetic algorithms or neural networks in order to provide fuzzy systems with learning capabilities . This paper presents a method for optimally sizing the energy storage system in microgrids.
5. Discussion Optimal microgrid sizing and system energy management can be optimized using a single-stage or a multi-stage methodology. A single-stage optimization approach poses a considerable challenge in promising a globally optimal solution.
Given the complexity and importance of these systems, it is essential to pay close attention to the design and operation of a microgrid. One of the primary stages in this process is energy planning, which includes selecting energy sources and sizing the sources chosen as a core step .
The results highlight that a microgrid composed of WT, PV, diesel, and BESS exhibits the lowest LCOE compared to alternative combinations. In , MILP is similarly employed; the authors explore scenarios wherein a PV-FC-BESS system fulfills residential energy requirements within a grid-connected microgrid environment.
The sizing of microgrids is a complex optimization problem that is typically addressed through a variety of methodologies, as illustrated in Figure 5.
In , an investigation is conducted on a microgrid system in an island territory, which incorporated multiple technologies such as PV, WT, biomass, and geothermal sources, among others, with the objective function of minimizing the overall costs of the system.
