Economic,Low-carbon and Reliable Multi-objective Optimal Configuration Method of Cloud Energy Storage for Microgrid Clusters
微电网群技术通过多微电网间的协同互补,促进了分布式可再生能源在微电网间的协同消纳,被认为是未来新型电力系统中分布式电源接入电网的重要方式之一.考虑微电网群中多微电网协同互济的特性,提出了一种面向微电网群的"集中共享、分散复用"云储能运营架构.其中,集中式储能面向微电网群中的所有微电网进行共享,以合作共建、容量共享的方式为所有微电网提供服务,旨在降低各微电网的储能使用成本;分布式储能主要服务于微电网群中的各个微电网,以保障各微电网自身的可靠性为主要目标,同时兼顾协同互济的储能复用需求.在此基础上,构建了经济、低碳及可靠多目标驱动的云储能双层优化配置模型,并基于第二代非支配遗传算法实现模型求解.然后,建立了微电网群云储能系统商业模式,基于Shapley值法及系统运行模拟实现云储能系统投资、运营成本及效益的合理分摊,提出云储能初始投资成本的分配方法.最后,基于IEEE 33节点系统搭建微电网群系统并开展算例分析,结果显示所提方法可提出面向不同投资偏好的云储能配置方案解集,并验证了云储能模式提升系统投资运营效益的有效性.
Microgrid cluster technology promotes the collaborative consumption of distributed renewable energy among microgrids through the coordination and complementarity among multiple microgrids,and is considered as an important means for distributed generators to access the grid in the future new power system.Considering the coordination and mutual assistance characteristics of the microgrid cluster,a cloud energy storage operation architecture for the microgrid cluster which realizes the shared use of both centralized and distributed energy storage facilities is proposed.Specifically speaking,centralized energy storage is shared among all microgrids in the microgrid cluster,providing services to all microgrids through collaborative construction and capacity sharing,aiming to reduce the energy storage usage costs of each microgrid.Meanwhile,the distributed energy storage mainly serves various microgrids in the microgrid cluster,with the main goal of ensuring the reliability of each microgrid itself,while also taking into account the demand of coordination and mutual assistance for energy storage reuse.On this basis,a multi-objective two-level optimal configuration model of cloud energy storage driven by economy,low-carbon and reliability is constructed,and the model solution based on the non-dominated sorting genetic algorithm Ⅱ is realized.After that,a business mode for cloud energy storage system in microgrid clusters is established.Based on the Shapley value method and operation simulation,a reasonable allocation of investment,operation costs,and benefits for cloud energy storage systems is achieved,and a method for allocating the initial investment cost of the cloud energy storage is proposed.Finally,based on the IEEE 33-bus system,a microgrid cluster system is built and case studies are carried out.The results show that the proposed method can provide a solution set of cloud energy storage configuration schemes for different investment preferences,and verify the effectiveness of cloud energy storage mode to improve the investment and operation benefits of the system.
