The Key Issues of the Research on Electricity Spot Market adapting to Large scale Hydropower System

Abstract

During the past decades, there has been rapid development of hydropower in southwestern China, with a large-scale hydropower system has been formed. With the deepening of the new electricity market reform, the spot market is playing a fundamental role in hydropower accommodation, which is an important direction of the next step. Combined with the current status of China’s hydropower development in the background of Yunnan Power Grid, Jinsha River and Lancang River, this paper has analyzed the operation characteristics of large-scale hydropower system. A series of key problems were summarized, including optimization of cascaded hydropower stations, the accommodation of hydropower in market environment, and high-head generating units with multiple vibration zones. Some practical methods are proposed to address these issues, with a view to providing support for the construction of China's electricity spot market.
