Study on model´s integrated representability and modeling method of power load

Practical load model is of great importance for the power system planning, design and operation. The characteristic of traditional dynamic load model are physical meaning clear and concise, easy for analyzing and optimization, but also have disadvantage. The idea of model representability is proposed in this paper, together with the quantitative index and three qualitative indexes for it. On this basis, the fuzzy comprehensive evaluation method of fuzzy set theory is adopted to scale the model´s integrated representability, which is used as the constraint for model identification optimization reconstruction. The case study clarifies the rationality of the indexes for the model´s integrated representability and its function in parameter identification
