【摘要】：风光互补发电能够有效缓解采用单一资源可能造成的输出功率波动,加强地区能源资源优化配置,提高系统供电可靠性。在规划阶段,为提高资源利用效率,迫切需要制订风光接入方案,确定并网极限容量;基于现有网架结构不同的接入方案,极限容量存在一定差异。通过最优潮流理论分析,在考虑风、光资源的不稳定特性基础上,建立了风光接入最优模型,采用跟踪中心轨迹内点法求解风光接在不同节点的极限并网容量,并以IEEE 30节点系统为例进行计算,验证了方法的科学有效性,并得出了风光接在系统重负荷节点上极限容量较大的结论。该方法可以为实际系统中的风电场、光伏电站的容量设计提供参考,具有工程应用价值。
[Abstract]:Wind and wind complementary power generation can effectively alleviate the fluctuation of output power caused by the adoption of a single resource, strengthen the optimal allocation of regional energy resources, and improve the reliability of power supply of the system. In the planning stage, in order to improve the efficiency of resource utilization, It is urgent to draw up the scheme of wind power access and determine the limit capacity of grid-connected network. Based on the different access schemes of the existing network structure, the limit capacity is different. By the analysis of optimal power flow theory, the wind is considered. Based on the unstable characteristics of optical resources, the optimal model of wind access is established, and the limit grid-connected capacity of different nodes is solved by using the interior point method of tracking center locus, and the IEEE 30-bus system is taken as an example. The scientific validity of the method is verified, and the conclusion is drawn that the maximum capacity of the wind-connected system on the heavy-load node is large. The method can provide a reference for the capacity design of wind farm and photovoltaic power station in the actual system, and has engineering application value.
