The authors in [14 - 16] used genetic algorithm to optimise the capacity of the hybrid energy system in microgrid. A simple numerical algorithm was developed and used to determine the optimal generation units capacity required for a standalone, wind, PV, and hybrid wind/PV system .
The total dumped energy is 3.85 × 10 5 kWh. The annual load is supplied by clean energy and the ESS. From the state of the single-day operation of the microgrid, the whole day's load is satisfied. For most of the day, the output of clean energy is higher than the load.
Currently, the study of the optimal capacity configuration of isolated microgrid is based primarily on annual time series data or typical day time series data, and the optimal analysis of DG and ESS capacity is performed under specific microgrid operation strategies.
TerraVerde Energy has developed two tools to assist in microgrid sizing. The first, TerraGrid, utilizes a Monte Carlo simulation to determine the ideal battery power and duration for a statistical analysis on duration of backup power availability.
In microgrids, batteries play an important role in supplying power when other power sources are insufficient, such as solar power and wind speed.
