Demand assessment for virtual energy storage of distributed user under the cloud mode
Distributed energy storage technology can change the temporal and spatial distribution of energy and can improve the flexibility of the distribution network to integrate the distributed renewable energy.Under the traditional mode,the cost of energy storage is high,and the utilization rate of energy storage resources is low.Cloud energy storage is a new business model that can respond to the demand for distributed energy storage.Under the cloud mode,the virtual energy storage configuration model is built by considering the factors that affect the demand for virtual energy storage,such as load,the output of renewable energy,time-of-use electricity price,and cost.A community with 14 typical users is selected as a case to verify the validity of the model established above.Case analysis shows that,under the cloud mode,the virtual capacity and power demand of energy storage for users are 18.2%and 7.1%lower,the annual cost is 4.12%lower,and the utilization rate of energy storage is 8.12%higher than it under the traditional mode.Therefore,the cloud mode of energy storage has a good prospect in the application.
