Nowadays, distributed generators in Microgrids (MG) are developed to exploit the clean and renewable energy from nature, such as solar irradiation, wind power, tidal wave, etc. Accordingly, an Aggregate Battery Energy Storage System (ABESS) is implemented to achieve the stability and reliability of MG. To be clearly decribed, the ABESS will play a main role as a power controller in supply-demand operation of MG. In order to demonstrate significance and importance of ABESS in the MG, its operation reliability will be introduced in this paper. The authors will use an analytical methodology based on Markov models to assess the operation reliability of the whole ABESS under dynamic operation cases. According to dynamic operation cases of MG with the ABESS and Photovoltaic Generation System (PVS), the failure rate of the ABESS is different. Simulations and test results are presented and discussed to prove that the operation reliability of the ABESS in the MG significantly depends on different dynamic operation along with the voltage dynamic and power loss.
