Electric Load Model Based on Aggregation Algorithm

At present, in the simulation program of power system, there are various load models whose parameters are generally assumed by experience. Thus, the simulation precision is not guaranteed. In this paper, according to the data investigated, a new load model based on load aggregation algorithm, with the distribution network impedance considered, is proposed. In this load model, transformer substation is equivalent to constant impedance, current and power load shunt-wound with an induced motor, series-wound with distribution impedance. Effectiveness of the proposed model is verified according to simulation.
