Section 3 presents a simple case study consisting in the robust optimization of a small microgrid with battery storage and aiming at characterizing the influence of the battery model in the design process. Section 4 gives the results associated with this case study and conclusions are presented in Section 5.
Real-time digital simulations were carried out for an islanded microgrid based on the IEEE 13 bus prototypical feeder, with distributed battery ES systems and intermittent photovoltaic generation.
Finally, based on the results obtained, it can be concluded that the proposed hierarchically controlled BESS power flow formulation is a useful and reliable bus model that can be used for steady-state analysis, design, and control in islanded microgrids.
As it can be observed, maintaining the microgrid frequency in an acceptable frequency band using a BESS equipped with a conventional FDC is only possible at a very high EPC and imposing a severe load shedding, and consequently the conventional FDC is unable to meet frequency requirement in an islanded microgrid.
Off-grid power systems based on photovoltaic and battery energy storage systems are becoming a solution of great interest for rural electrification. The storage system is one of the most crucial components since inappropriate design can affect reliability and final costs.
Several components of microgrids have been extensively studied, and a variety of models have been developed and reported in the lit-erature. However, since inverter-based BESS are relatively new elements of microgrids, fewer studies have been conducted on their modeling and control.
