Day-Ahead Optimal Dispatching of Heating System When Electrode Boiler Participating in Frequency Regulation Service

In order to improve the efficiency and investment benefits of the electrothermal integrated energy system,an optimal dispatching method for heating system under the frequency modulation service with the participation of electrode boilers is proposed,which takes advantage of the flexible regulation and fast response of the electrode boilers. Firstly,the frequency regulation modes of power system are introduced and a method for calculating the benefits of frequency regulation under PJM ancillary service compensation mechanism of frequency regulation market is proposed. And on the basis of the heat demand response,the operation mechanism of the electrode boiler is established,and the day-ahead prediction method for the ability of the heat demand response is proposed. Then,a day-ahead optimal dispatching method aiming at maximizing the total benefits of heating and frequency regulation for operators is established. Finally,an example is given to verify the effectiveness of the model. The results show that the participation of electrode boiler in frequency modulation can improve operators’ benefits,which is of great significance to promote the development of electrothermal integrated energy system.
