Due to the uncertainty of PV output, the flexibility of energy storage system regulation, the complexity of user power load demand, and the difference of peak and valley electricity prices, the benefits of distributed PV and energy storage microgrid are more derived from system benefits, and the traditional power technology and economic evaluation methods are limited. In this paper, the production simulation model is used to simulate the impact of typical distributed PV micro grid system on the overall operation and energy costs, and the comprehensive system benefits of typical distributed PV micro grid are comprehensively evaluated.
