Abstract:

  The integration of Northwest renewable power resources in Northwest area is mainly restricted by the transmission capability of the Northwest-Xinjiang power corridor. In order to make reasonable development planning of the Northwest renewable power resources, this paper studies the relations of the integration of renewable power resources to the transmission capability of the Northwest-Xinjiang power corridor and the power system's security and stability. We adopt PSD-BPA electromechanical transient simulation program to analyze the impact of wind power integration in Xinjiang Hami, Gansu Hexi Corridor and PV power integration in Gansu Jinchang, Qinghai Qaidam on the transmission capability of the Northwest-Xinjiang power corridor and the power system's security and stability. The results indicate that the Hami wind power's integration and the Hami wind power units' control mode have small influence on the transmission capability of the Northwest-Xinjiang power corridor, but the Hami wind power's integration will decrease the power system's stability; the Gansu wind power and PV power's integration will increase the transmission capability of the Northwest-Xinjiang power corridor and the power system's stability; the Qinghai PV power's integration will decrease the transmission capability of the Northwest-Xinjiang power corridor and the stability of the first corridor of the Northwest-Xinjiang power corridor, but the total integration amount of the renewable power resources will be greatly increased. According to the analysis results, it is suggested that the development scale and the scale ratio of the Gansu and Qinghai PV power resources should be reasonably made, and the development proportion should be paid attention. Meanwhile, the suitable security and stability control measures should be made when the power system has large scale wind power and PV power's integration.
