Method and device of power system load fuzzy modeling
Xinrui Liu · Electric Power · 2009
The most difficult aspect of load modeling, which differentiates itself from other modeling problems, lies in the fact that the load is time-variant. Single polynomial model or exponential model in measurement-based theory can't satisfy the request, and other input-output models are very hard to realize. Aiming at the characteristic of the load modeling and fuzzy T-S model, the fuzzy T-S model for non-linear dynamic load model was proposed. To a certain extent it solves the problem based on strong time-variant of the load and predigests the complicate model. And the simulation results of T-S fuzzy model are more accurate than the simulation results of traditional polynomial modelandexponentialmodel.Theload modeling device hardware was designed. The application on powerload modeling results shows validity and practicability of the method.
