Abstract: 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.

Key words: classified power flow tracking, network losses allocation method, UHV transmission, proportional power flow tracking method, average power flow tracking method
