The application of the heat storage tank in combined heat and power(CHP)units can contribute to improving the cogeneration system's abilities in peak-load regulation and wind power consumption. Since the use of the heat storage tank increases the difficulty in optimal dispatching

a novel power scheduling strategy based on two linear models is proposed to coordinate the operation of CHPs and heat storage tank. For the proposed scheduling strategy

the operation state of heat storage tank can be pre-judged

and the two technical indexes including the rate of wind power curtailment and the growth rate of running cost are taken into account. According to the adjustments of electric power and thermal power

wasted wind power and running cost can be reduced

respectively. Furthermore

an optimal dispatching plan is obtained in consideration of the uncertainty of wind power generation. Numerical examples are conducted to demonstrate the effectiveness of the proposed scheduling strategy in achieving efficient utilization of the heat storage tank

improvement of wind power consumption and decrease in operation cost.
