Multi Source System Unit Commitment Considering Thermal Storage Electric Boiler with High Proportion of Wind Power

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.
