Abstract

Abstract:

In this paper,the design method of an emergency voltage controller for the power systems containing wind farms is presented based on the nonlinear model-predictive control theory. In this method,a receding dynamic optimization model is proposed based on the quasi-steady-state approximate models of power systems. Then,the proposed model is described as an optimal control problem with continuous and discrete time differential-algebraic equations,with the purpose to achieve voltage deviation and control cost minimization. Moreover,Radau collocation method is used to convert the proposed model into a nonlinear programming problem which can be solved by using the optimization solver IPOPT through the modeling software AMPL. Finally,the effectiveness of the proposed method is verified on the modified New England 10-machine 39-bus system.

Key words: wind farm, long-term voltage stability, model predictive control, Radau collocation method, nonlinear programming
