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.
To simulate the microgrid and conduct the analysis on the models, certain requirements must be fulfilled. This includes obtaining input data to evaluate the production and demand at each time step, as well as determining the values of the sizing and operating variables.
