Active power economic dispatch of wind farm cluster based on integer linear programming

Abstract

The existing active power control methods which take single wind farm as a unit and regulate it independently cannot satisfy the complex control demand of large-scale wind power base. Therefore, wind farms are unitized as wind farm cluster (WFC) as a whole in this paper. An active power economic dispatch model of WFC considering short-term wind power prediction is proposed, which aims at maximizing the active power output of WFC while minimizing tie line power loss. As this dispatch model is a complicated integer programming problem with nonlinear constraints, it is transferred to the integer linear programming (ILP) problem and solved by commercial MILP solvers under the general algebraic modeling system (GAMS). Simulation results of an actual WFC in Northeast China proved the method to be effective and feasible.
