An interactive load modeling based on decision-making method

Load modeling is one of the most critical problems that are urgent to be solved in power system modeling. Accurate load models will have significant meaning in power system digital simulation, dynamic security and stability assessment. Synthesis Load Models (SLM) considers the impact of power distribution network and compensation capacitor, while randomness and variability of power load are precisely considered in the traction power load model. In this paper, traction power system load model and synthesis load models are interacted by using analytic hierarchy process (AHP). Weight coefficient of two models can describe the power model internal change and connection. Simulations results proved that the interactive load modeling can effectively improve the accuracy of load models and the AHP is feasible in power system load modeling application.
