In view of the influence of load distribution on energy storage application target and capacity demand

a new load zoning method for energy storage capacity allocation is proposed. According to the characteristics of power grid load and new energy output

the peak valley subordination degree is taken as the index of load characteristics

and the new energy anti peak regulation and large fluctuation are taken as the indexes of new energy output. The fuzzy clustering of these two indexes is used to obtain the load partition. Finally

combined with the actual operation data of Xinjiang new energy grid connected system

the above load zoning method is simulated and verified. The results show that

when allocating the energy storage capacity

using this zoning method to provide accurate load zoning for the energy storage charging and discharging power control model can suppress the anti peak regulation and large wave dynamics of new energy sources

and increase the capacity of the power grid to absorb new energy.
