摘要：

随着国家“双碳”政策的持续推进，储能应用场景层出不穷。用户侧小型储能具有体积小、部署方便、应用灵活等优点，但是过于随机的调度模式也给电网运行带来隐患。用云储能理念入手，实现用户侧小储能装置的互联互通，提出了云储能服务系统架构及运营模式，并设计了云储能模式下小型储能装置的集群调度策略。通过设计具体仿真算例验证方法的可行性。验证结果显示所提出的运行模式和优化调度方案可落地、易实施、有成效，是对储能应用新场景的一种有益探索。

Abstract:

With the continuous advancement of the "dual carbon" target， energy storage application scenarios are emerging endlessly. Small energy storage units on the user side have advantages of small size， convenient deployment and flexible application. However， the overly random scheduling mode also brings hidden dangers to the operation of the power grid. Based on the concept of cloud energy storage， the interconnection and interoperability of small energy storage devices on the user side can be realized， and the architecture and operation mode of cloud energy storage system are proposed. Then， a cluster scheduling strategy for small energy storage devices under cloud energy storage mode is designed， whose feasibility is verified by simulation examples. The simulation results show that the proposed operation mode and optimized scheduling scheme are feasible， easy to implement， and effective， which can facilitate the application of energy storage units in new scenarios.

Key words: user side energy storage, cloud energy storage, optimize scheduling, "dual carbon" target, operation of power grid, cluster scheduling strategy
