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.
