Impact Evaluation of Operation Strategies of Multiple Energy Storage Systems on Reliability of Multi-energy Microgrid

In view of the research background that the effect of energy storage on the reliability of energy supply is still to be excavated, the effect of multiple energy storage on the reliability of energy supply is quantitatively analyzed by formulating different operation strategies of energy storage link and combining relevant reliability indices. Firstly, taking the multi-energy microgrid as the research object, the energy efficiency model of key device is constructed. Secondly, different operation strategies for the energy storage devices are formulated, and the corresponding indicators are sorted out to analyze the characteristics of energy storage device and the impact on the system reliability. Finally, the effect of different configuration of energy storage devices and different operation strategies on the reliability of energy supply system are analyzed quantitatively by actual examples. This paper focuses on the analysis of the impact of the energy storage link of multi-energy microgrid on the reliability of energy supply system, thus providing guidance for the planning of energy storage device.
