Abstract

Abstract: Conventional power flow tracing uses proportional sharing assumption in calculating nodal sharing, and its models are generally algebra equations. In order to promote the application of power flow tracing, a real power flow tracing optimal modeling is established in this paper based on a real power network flow. This model establishes attributive constrains and decision-making objectives from mathematical optimization perspective. The attributive constrains make the power flow tracing satisfy the real power balance of network, and the decision-making objective can be established according to the real application. The method for establishing the decision-making objective is demonstrated through two application examples, including load nodal power price and power price competitions. When applied to calculation of load nodal power price, the model can better reflect the fair sharing principles of transmission networks. When applied to calculation of power price competitions, the model can give the maximum and minimum power price competition result of power flow tracing.

Key words: power flow tracing modeling, real power flow tracing optimization, proportional sharing assumption, nodal power price, power
