Abstract: An evaluation method for wind power accommodation of the thermoelectric power plant is proposed by considering the actual operation conditions. When the heat load is same,the wind power accommodation capacity of the thermoelectric power plant with solid heat storage boilers is 3.23 times stronger than that with the heat storage water tanks. Three first level evaluation indicators of energy,operation and economy and ten second level evaluation indicators of fire safety index,energy utilization index and so on are evaluated for multi-objective comprehensive optimization. It shows that the wind power accommodation and the civil engineering cost are two important factors which should be more considered. The comprehensive advantage of the thermoelectric power plant with heat storage water tanks is better than that with solid heat storage electric boilers.
