| Notes | power systems; emergency voltage control; PWA approximating; MLD model; explicit model predictive control ZHANG Ju, CHEN Yuan, DING Jing （College of Information Engineering, Zhejiang University of Technology, Hangzhou 310032, China） 41-1401/TM Because power systems incorporate not only nonlinear dynamics but also discrete events and some discrete manipulated variables, a power system is in essential a complex hybrid system. After describing the nonlinear dynamics, discrete events and variables of power system with Mixed Logical Dynamic （MLD） and Piece Wise Aftlne （PWA） respectively, a hybrid model of power system is developed. The explicit model predictive control technique is applied to MLD model of the power system to control the voltage collapse in power systems. Numerical simulations show that the explicit model predictive control can successfully stabilize the voltage, predict and prevent a voltage collapse in the power system, and can respond rapidly to fault situations in the power system, and thus show t |
