Therefore, the optimal allocation of small energy storage resources and the reduction of operating costs are urgent problems to be solved. In this study, the author introduced the concept of cloud energy storage and proposed a system architecture and operational model based on the deployment characteristics of user-side energy storage devices.
Cloud Energy Storage Service Mechanism Business Process. The advantage of the cloud energy storage model is that it provides an information bridge for both energy storage devices and the distribution grid without breaking industry barriers and improves the efficiency of energy exchange.
Based on the day-before optimal scheduling model and forecast information, the cloud energy storage service provider formulates a cluster scheduling matching strategy for energy storage devices, which ensures the economic benefits of users, improves the consumption space of new energy, and promotes the peaking and valley filling of the power grid.
The SOC constraints of the cloud storage energy mean that the storage energy cannot be overcharged or discharged during operation, indicates the change in external characteristics of ES in year y, and Cycles indicates the number of optimisation cycles within the warranty period.
Then the evaluation methods of energy storage utilization demand from CES users are proposed, including the evaluation of the renewable power curtailment, system minimum inertia requirement, and the equivalent energy storage ability of DHS.
Based on this evaluation results, a bi-layer optimal energy storage planning model for the CES operator is established, where the upper-layer model determines the installed capacity of lithium (Li-ion) battery station and the lower-layer model determines the optimal schedules of the CES system.
