Abstract

Abstract: In order to solve the problem of output fluctuations of active power occurring in directly-driven wind power generators integrated with power grid, based on the method of paralleling a superconducting magnetic energy storage system(SMESS) to the converter and the wind speed model analysis, a control strategy for the chopper of the SMESS was proposed with pulse judgment plus dual closed-loops, which can make the SMESS have energy throughput quickly and accurately, obtaining the results of maximum wind energy capture and smoother active power to the grid. Simulation of a directly-driven wind power generator with a superconducting magnetic energy storage system proves the correctness and effectiveness of the controlling strategies.

Key words: wind power generation system, directly-driven, wind speed model, superconducting magnetic energy storage, smoothing control of output power
