摘　　要：目前电力系统对微电网集群的上网需求越来越大,为了提高其灵活性和安全性,基于云网协同,提出了一种用于模拟和评估微电网集群的新型分布式算法。在这种算法中,将发电能力不足的分布式微电网定义为电力短缺微电网,这类只供应其内部负载。通常数据中心的能耗非常高,这是智能电网的主要负荷。数据中心需求响应是一种有发展趋势的响应,可激励云服务器使其适应电网条件。这不仅可以缓解智能电网的运营稳定性问题,还可以降低云运营商的电费。运营商可以通过云网协作管理其工作负载来提高其效率并降低能源成本。还考虑了独立云运营商与联合云运营商在需求响应下的交互系统。利用合作博弈论,考虑了云运营商之间的联合体形成。通过仿真结果表明,新型的分布式算法增加了智能电网的利润和性能。At present,the power system needs more and more microgrid clusters to connect.In order to improve its flexibility and security,this paper proposes a new distributed algorithm for simulating and evaluating microgrid clusters based on cloud network collaboration.In this algorithm,a microgrid with sufficient generating capacity is redefined as a microgrid with power shortage to supply its internal load.The energy consumption of data centers is very high and constitutes the main load of smart grid.Data center demand response is an evolving response that can motivate cloud servers to adapt to grid conditions.This not only alleviates the operational stability of the smart grid,but also lowers the power bill for the cloud provider.Cloud providers can improve their contributions and reduce energy costs through collaborative cloud network management of their workloads.This paper considers the interaction system between independent cloud providers and federated cloud providers under demand response.Based on cooperative game theory,this paper considers the formation of a consortium between cloud providers.Simulation results show that the new distributed algorithm increases the profit and performance of smart grid.
