OPTIMAL CAPACITY ALLOCATION OF REGIONAL SHARED ENERGY STORAGE SYSTEM INTEGRATING DISTRIBUTED WIND-HYDROGEN USER GROUPS
Regional shared energy storage scheme introduced into a wind-hydrogen-heat coupled system for distributed wind power multi-user groups,which is a two-tier planning model in which the upper tier objective is the highest daily operational benefit from the regional shared energy storage,and the lower tier objective is the lowest daily operational cost for the distributed wind power user group.Among them,the upper layer model achieves the effect of reducing the cost of energy storage investment and increasing the utilization rate of energy storage through the optimal allocation of regional shared energy storage capacity;and the lower level model is designed to optimize the reliability,economy and flexibility of the operation of the wind-hydrogen coupling system through the multiple interactions of distributed wind power with electrical loads,thermal loads,hydrogen storage and regional shared storage services.Modeling and calculation with data from a distributed multi-user cluster wind-hydrogen-heat-storage system in Inner Mongolia.The results show that regional shared energy storage can effectively reduce the initial investment of energy storage and improve the overall economy of the system when it is introduced to the distributed wind power user group.
