As wind turbine output is proportional to the cubic of wind speed, the wind turbine generator output fluctuates due to wind speed variations. Hence, if the power capacity of wind power generators becomes large, wind power generator output can have an influence on the power system frequency. Since Superconducting Magnetic Energy Storage (SMES) system has the ability to provide both active and reactive...
Since a superconducting magnetic energy storage (SMES) unit with a self-commutated converter is capable of controlling both the active and reactive power simultaneously and quickly, increasing attention has been focused recently on power system stabilization by SMES control. In this study, a fuzzy gain scheduled supplementary control scheme with SMES unit is proposed and applied to automatic generation...
With the increase in size and capacity of electric power systems and the growth of widespread interconnections, the problem of power oscillations due to the reduced system damping has become increasingly serious. Since a superconducting magnetic energy storage (SMES) unit with a self-commutated converter is capable of controlling both the active and reactive powers simultaneously and quickly, increasing...
This paper presents a combination system of wind power generator and hydrogen generator. The output of wind power generator, in general, fluctuates greatly due to wind speed variations, and thus the output fluctuations can have a serious influence on the power system operation. In the proposed system, Doubly-Fed Synchronous Generator (DFSG) is used as an adjustable speed wind generator, and an electrolyzer...
This paper proposes a wind power generation system composed of a wind turbine generator, a hydrogen generation device, and an energy capacitor system (ECS), which are controlled cooperatively. It can supply the electric power with low fluctuation to the electric power system as well as generates hydrogen constantly. The output of wind turbine generators, in general, fluctuate greatly due to wind speed...
