Abstract
Aiming at the centralized and distributed investment modes of shared energy storage (ES) and the operation modes of power sharing and capacity sharing, the multi-scenario optimization models considering the seasonal differences of renewable energy generation and user load are established, and a pricing mechanism based on the ratio of supply and demand is adopted to economically settle the power transaction in the system. In order to evaluate the impact of the load flexibility on ES planning and total system cost, the modeling and sensitivity analysis for flexible load of user are carried out. Finally, combined with the real historical data, different investment and sharing modes are analyzed and compared from multiple perspectives through case studies. And the impact of peak valley electricity price difference and scale investment effect on ES investment and operation is further analyzed. The results show that the operation mode of centralized ES investment and power sharing are more economical.
