Abstract

Abstract: In recent years, wind power digestion has become a major bottleneck in wind power large-scale development. Wind power has characteristics of little in day, much in night and anti-electricity lag. Introduction of time-of-use (TOU) price to adjust the users’ load can digest wind power effectively. Therefore, wind/thermal power joint-run optimization model is constructed based on TOU price under the background of the energy-saving generation dispatching way and the target of minimizing the cost of coal-fired cost and unit commitment. With the numerical example, it is found that the TOU price can realize the goal of peak load shifting, increasing wind-connect amount and reducing the system’s coal consumption compared with the result before the implementation of TOU price.

Key words: wind power, thermal power, joint optimization, energy-saving generation dispatching, time-of-use (TOU) price
