基于云储能容量动态分配的微电网系统双层优化模型OA北大核心

The rapid charging and discharging capacities of energy storage system(ESS)can effectively address the issue of intermittent and uncertainty of renewable energy and its loc-al consumption.The utilization of energy storage equipment on a large scale is hindered by the high initial investment cost and vacant energy storage capacity.However,in order to increase the utilization rate of energy storage equipment and reduce the vacancy rate of energy storage equipment,a dynamic alloca-tion model of cloud energy storage capacity,which accounts for demand response,was proposed based on traditional cloud en-ergy storage.First,in this paper we proposed a cloud energy storage capacity dynamic allocation strategy and established a model based on the essence of cloud energy storage leasing ser-vice.Then,the users accessing the cloud energy storage with renewable energy were modeled.To comprehensively examine the interconnections between users and cloud energy storage operators,as well as deeply explore their coupling relationship,a two-layer optimization model was established.The upper lay-er takes the maximum profitability of the cloud storage operat-or as the objective function,while the lower layer takes the lowest daily operating cost of the user as the objective function.The simulation results indicate that the proposed dynamic en-ergy storage capacity allocation strategy and model can in-crease the utilization rate of energy storage devices,reduce the vacancy of energy storage capacity,and also exhibit a good economy.
