Roadmap of Developing Active and Reactive Power Dispatch and Control System of China Grid Considering Large-Scale Wind Integration

Abstract

AbstractLarge-scale wind power is integrated into the backbone grid of China increasingly and the penetration of wind power grows higher and higher. In order to eliminate the impacts of wind power on conventional Active and Reactive Power Dispatch and Control (ARPDC) system, it is urgent to modify present system. Firstly, traditional ARPDC system is introduced briefly. Secondly, the basic characteristics of Chinese wind power are analyzed and summarized, including fluctuation, low-predictability, low-controllability, centralized development, long-distance transmission and integration into backbone grid. Thirdly, based on the characteristics of wind power, the framework of the new ARPDC system is proposed. In short, the ultimate goal of the new ARPDC system is that the wind power should play almost the same role as conventional power generation units. Finally, the status quo of the development of ARPDC system suitable for large-scale wind power integration in China is introduced, and the roadmap of developing new ARPDC system is discussed.
