The insufficient wind power accommodation ability in the heating supply period in northwestern region is caused by the heat-load-based combined heat and power（CHP） unit during the winter heating period. We proposed a strategy of accommodation of wind curtailment in heating season in which the joint operation of concentrated solar power（CSP） with thermal energy sterage（TES） and electric boiler was taken into consideration. The CSP plant and electric boiler which supply the heating load of the system with CHP units are taken into consideration in the strategy to increase the peak shaving capacity of CHP units and improve the wind accommodation of system. Meanwhile

the thermal energy storage of CSP can be used to store and time-shiftily use thermal energy by considering the joint operation of CSP and electric boiler. The results based on the IEEE-30 bus and actual system show that the strategy proposed by this paper can improve the wind accommodation of the system while increasing the rate of utilization of solar heat energy and decreasing the total cost of the system. The research results can provide a reference for the combined heat and power scheduling during the heating supply period in Northwest China.
