Abstract

A new unit commitment model of multi-source system considering thermal storage electric boiler with high proportion of wind power is proposed. The energy storage function of thermal storage electric boiler is fully exerted, so that it can cut peak and fill valley in the system, so as to improve the system's capacity of energy consumption for wind power and the economy of system operation. The membership function is used to transform the double objective with the lowest generation cost and the lowest heating cost into the single objective with the highest comprehensive satisfaction. The proportion of the influence of the two costs on the comprehensive satisfaction can be determined according to the demand by adjusting the expansion value of the two objectives, so as to facilitate the flexible solution. The results show that considering the unit commitment of thermal storage electric boiler has good effect on improving the wind power consumption capacity and the operation economy of the system.

考虑风电比例高的蓄热电锅炉多源系统机组承诺

提出了一种考虑高风电比例蓄热电锅炉的多源系统机组承诺模型。充分发挥蓄热电锅炉的蓄能功能，在系统中削峰填谷，从而提高系统的风电消纳能力和系统运行经济性。利用隶属度函数将发电成本最低和供热成本最低的双目标转化为综合满意度最高的单目标。通过调整两个目标的扩展值，可以根据需求确定两种成本对综合满意度的影响比例，便于灵活解决。结果表明，考虑蓄热电锅炉的机组承诺对提高系统的风电消纳能力和运行经济性具有良好的效果。
