Analysis on Peak Load Regulation Status Quo for Coal-fired Power Plants in China
-
Abstract
With the development of "Global Energy Internet" , wind power, the installation of solar power and other new energy power generation increases a lot. One of the most urgent problems facing power grids in China is the growing peak-valley difference. Coal-fired power plants, the main power supply, have to play an important role in peak load regulation in the future. Peak shaving demand, operation modes and new problems threaten the safety of units and relevant support policies were summarized and analyzed in this paper. Results showed that the main and auxiliary equipment deviates from the best operation condition when they take participate in the peak regulation, which would cause high safety barriers, energy-consuming problems, and environmental pollutants and some other issues. Finally, this work provides some guidance for policy-making and power grid dispatching with some recommendations to deal with the peak load regulation problem.
