Model Predictive Control Security Economic Dispatch Model Considering Transmission Line Thermal Inertia Effect
摘要
Abstract
A power system security economic dispatch model considering transmission line thermal inertia effect was proposed based on model predictive control methodology. Originally, the meteorological parameters along the conductor were predicted with ARMA model, while the line current was predicted with sensitivity matrix under DC power flow network model. Thus, the future conductor temperature was estimated. Then a receding horizon optimization dispatch model in quadratic programming form was constructed, in which the estimated temperature of transmission line was limited by the maximum allowable temperature instead of traditional ampacity. In the end, the real measuring outputs were taken as the feedback information to close the control loop. On one hand, model economy is promoted by transmission line thermal inertia effect; on the other hand, system security is guaranteed by model predictive control. A simulation was carried out to demonstrate the validity of the proposed model.关键词
