A New Method of Calculating Complex Power Dynamic Distribution Factors by Circuit Theory

In the electricity market, analyzing the distribution of complex source power in the network is the theoretical basis of confirming transmission service and wheeling service cost, etc. The analyzing method of based on the current and voltage can be seen as the question of how to allocate the nonlinear function value to its independent variables, but its solution is not unique. This paper, based on the one-dimensional characteristics of energy, derives the complex power dynamic distribution factors by circuit theory in the energy space. These factors reflect that the distribution of source power is not only determined by topology of system and the line parameters, but also determined by the system state. According to these factors, the distribution of source power in the system is linear; line flows and losses are the different forms of source power. Finally, IEEE9-Bus system verifies the correctness of the proposed method.
