Retracted: Combined Research on Thermoelectricity to Enhance the Capacity of Renewable Energy

Using renewable energy is the trend of world energy development. The volatility of renewable energy is increasing along with its installed capacity magnifying, resulting in abandoned wind, light and other issues, impacting on renewable energy consumption seriously. In order to solve this problem, trading the abandoned wind and light and using them supply heat based on power market means under the existing scheduling system can effectively promote the elimination of renewable energy, reduce the consumption of fossil fuels such as coal, and protect the environment. The coordinated optimization of combined electro-thermal system containing renewable energy for heating with controllable electric heating devices is researched in this paper to improve the consumption of renewable energy. The specific research contents are as follows: Firstly, a method for decomposing the monthly trading power of the combined electro-thermal system is put forward based on the monthly trading of abandoned wind and light. Then, arranging the day-ahead schedule plan according to the decomposition of the monthly transaction volume. The electric heating device is taken as the main control object in the day-ahead dispatching, and the double-layer optimal dispatching and control model of the combined electro-thermal system is established. Finally, the online rolling optimization scheduling model is established based on the above researches of the grid was analyzed.
