Study on Control Strategy of Optimal Power Tracking of Multi-MW Wind Generating Set

Abstract

Recently, an increasing number of multi-MW (1MW and up) wind generating set are being developed with a variable speed-variable pitch (VS-VP) control strategy to improve the fast response speed and get optimal energy. But the power generated by wind turbine changes rapidly because of the continuous fluctuation of wind speed and direction, and wind energy conversion systems are of strong nonlinear characteristics because of many uncertain factors. By analyzing the mathematical model of doubly-fed induction generator (DFIG), this paper presents a kind of control strategy of optimal power tracking. Fuzzy adaptive PID controller (FAPIDC) is adopted, and simulation results show that the controller can compensate the nonlinearity and have excellent robustness.
