A synthesis load model with distribution network for power transmission system simulation and its validation

The deficiencies of existing load models and their implementations in power system simulation programs are addressed in this paper. To improve the load model for power system simulation, a Synthesis Load Model (SLM) with distribution network, which is consistent with the structure of power loads and distribution networks, is presented. The SLM is reasonable in structure and convenient to use. The SLM can simulate the load components and distribution systems including distribution network, reactive compensation and the generators connected to low voltage networks. The validity of SLM has been validated by four field tests of three-phase short circuit in Northeast China Power Grid in the years of 2004 and 2005 respectively.
