Voltage Regulation Using a Permanent Magnet Synchronous Generator with a Series Compensator: Preprint Open
A wind power plant (WPP) is often operated at unity power factor, and the utility host where the WPP connects prefers to regulate the voltage. Although this may not be an issue in a stiff grid, the connection to a weak grid can be a proble…

Smart substation integration technology and its application in distribution power grid Open
At present, smart substations use the IEC61850 standard based on the architectural framework of three layers and two networks to realize information digitization and advanced applications. Although the smart substation offers many improvem…
View article: Assessment of system frequency support effect of PMSG-WTG using torque-limit-based inertial control
Assessment of system frequency support effect of PMSG-WTG using torque-limit-based inertial control Open
To release the 'hidden inertia' of variable-speed wind turbines for temporary frequency support, a method of torque-limit-based inertial control is proposed in this paper. This method aims to improve the frequency support capability consid…
