Control Strategy of Wind Turbine Based on Permanent Magnet Synchronous Generator and Energy Storage for Stand-Alone Systems - 2017

ABSTRACT:

This paper investigates a variable speed wind turbine based mostly on permanent magnet synchronous generator and a full-scale power converter in a stand-alone system. An energy storage system(ESS) as well as battery and fuel cell-electrolyzer combination is connected to the DC link of the complete-scale power converter through the facility electronics interface. Wind is the first power source of the system, the battery and FC-electrolyzer combination is employed as a backup and a long-term storage system to supply or absorb power within the stand-alone system, respectively. In this paper, a control strategy is proposed for the operation of this variable speed wind turbine in a stand-alone system, where the generator-facet converter and also the ESS operate along to meet the demand of the hundreds. This management strategy is competent for supporting the variation of the masses or wind speed and limiting the DC-link voltage of the full-scale power converter in a very tiny vary. A simulation model of a variable speed wind turbine in a stand-alone system is developed using the simulation tool of PSCAD/EMTDC. The dynamic performance of the stand-alone wind turbine system and also the proposed management strategy is assessed and stressed with the simulation results.
