This paper proposes a control methodology for Superconducting Magnetic Energy Storage (SMES) unit, which can significantly decrease the voltage and power fluctuations of grid connected fixed speed wind generators. The SMES system with a voltage-source IGBT converter and two-quadrant DC-DC chopper using IGBT is proposed as a controllable energy storage device. The objective of the proposed SMES control...
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...
Due to random variations of wind speed, the output power and terminal voltage of a fixed speed wind generator fluctuate continuously. These irregularities in power output are characteristic of intermittent energy sources such as wind energy, affecting both the power quality and planning of the energy storage system. It is reported that STATCOM/SMES (superconducting magnetic energy storage) topology...
This paper proposes a robust controller for superconducting magnetic energy storage (SMES) unit to stabilize a grid connected wind generator system. In the proposed controller, both SMES active and reactive powers are controlled to decrease the fluctuations of output power and terminal voltage of the wind generator during abnormal conditions. In particular, the SMES controller is designed to enhance...
