基于分类潮流追踪法的特高压输电网损分摊

UHV Transmission Loss Allocation Based on Classified Power Flow Tracing Method

为探究适合于网损分摊的方法,结合国内交直流特高压输电网发展规划与趋势,探讨电力市场中各种网损费用的分摊方法并分析它们在特高压电网中的适用性。依据交直流特高压系统中造成网络损耗的各部分电力设备的特性,提出分类潮流追踪的特高压输电网损分摊方法,该方法依据复功率潮流计算结果,结合比例潮流追踪法分摊变动网损,根据用户年典型潮流和电网使用率采用平均潮流追踪法分摊固定网损。最后通过IEEE 30节点交直流改进系统仿真算例,将网损分摊结果与传统潮流追踪法网损分摊结果对比,验证该方法的可行性及合理性。

In order to choose an appropriate method for network losses allocation,this paper discusses the allocation methods for various network losses in power market,and analyzes their applicability in the UHV power grid.According to the characteristics of the power devices which cause the losses of the network in various parts of the AC/DC power system,this paper proposes a new UHV network loss allocation method,namely classified power flow tracing method,which allocates changing network losses using proportional power flow tracing method based on AC/DC hybrid power apparent flow calculation results,and allocates the fixed network losses using average power flow tracing method based on consumer typical power flow and network usage rate.At last,the rationality and feasibility of the classified power flow tracing method are proved through the AC/DC simulation results of the improved IEEE30 node system and comparison with the traditional power flow tracing method.
