Multi-element optimization control method of power grid partition integrated with wind power cluster

随着风电大规模、高比例并网运行,在风电集群区域建立多元相济的电力系统控制模式是提高系统调峰能力、缓解风电消纳困境的有效途径。在分析风电受阻主要因素的基础上,提出以集群风电的送出断面划分控制区域,综合考虑各区域内负荷的调节特性及各类型电源的调峰特性,以风电受阻电量最小为目标,建立分区多元优化控制模型并进行求解,形成火电、水电、风电、可调节负荷的优化控制方法。以某地区电网为例,验证所提分区多元优化控制方法的有效性。

With the large scale and high proportion of wind power connected to power grid, the establishment of multi-element control mode in the power system with wind power cluster is an effective way to improve the peak adjust me nt ability and alleviate the plight of wind power consumption. On the basis of analyzing the main factors of wind power blocking,the control area is divided based on the sending cross section of the cluster wind power. Comprehensively considering the load regulation characteristics and the peak regulating characteristics of various types of power supplies, the multi-element optimization control model of power grid partition is established and solved with the minimum blocked wind power as its objective, based on which , the optimization control method of thermal power, hydropower, wind power and adjustable load is formed. Taking a regional power grid as the example , the effectiveness of the proposed method is verified.
