摘要：

In order to solve the problem of capacity selection of heat storage tank under "wind thermal conflict", the whole heating period of combined heat and power plant was taken as the research object. By introducing the concept of characteristic day, the hourly operation model of combined heat and power plant with heat storage tank is established. The optimal value of the thermal capacity for the tank was found by taking the increment of the peak adjustment space, the annual total income and the 10-years'net present value as the objective functions. The results show that a higher thermal load makes a greater optimal capacity of the heat storage tank. Meanwhile, the peak adjustment space of combined heat and power plant is also larger. When the initial investment is not taken into account, the optimal capacity of the heat storage tank targeted at annual revenue is about 820 MW. When considering the initial investment, the optimal capacity of the heat storage tank targeted at the 10-years'net present value(NPV) is about 430 MW, and the capacity is almost halved. © 2021, Solar Energy Periodical Office Co., Ltd.
