Research on optimal configuration of electrochemical energy storage in"double high"power grid considering utilization efficiency of new energy
With the increase in the proportion of renewable energy represented by photovoltaic and wind power,the phenomenon of wind and solar abandonment has emerged due to the volatility and randomness of new energy output.This article proposed a"dual high"electrochemical energy storage optimization configuration model for the sending-end power grid considering the utilization rate of new en-ergy.The new energy volatility index was used for energy storage location selection,and the tracking center trajectory interior point method was used to solve the energy storage capacity.Finally,based on the historical output data of Zhangbei area,simulation was con-ducted to determine the minimum energy storage required for different new energy utilization rates and different charging and discharging times.Finally,a relationship diagram between new energy utilization rate and energy storage capacity was drawn.Research has shown that this optimization model can improve the utilization rate of new energy in the sending-end power grid with a high proportion of new energy,laying the foundation for large-scale energy storage investment in the power system.
