Optimized Heat Storage Control Strategy for Combined Operation of Wind Power and Thermoelectric Storage Boiler

With the continuous expansion of wind power installed capacity in China, the scale of wind power integration in the North Region is also growing. During the winter heating period, the operation mode of pricing electricity based on heat amount and cogeneration units is forced to output electricity, it’s one of the most important factors for the abandonment of wind power in the northern region. The configuration of heat storage and electric boilers is an effective mean to enhance their regulation capabilities and increase the amount of wind power accommodation. In this paper, a comprehensive control strategy is proposed for combined operation of wind power and thermoelectric storage boiler, based on thermal power, cogeneration unit operating cost and abandoned wind cost. The simulation models were built to study the control strategy of heat storage device and introduces environmental penalty cost, and to analyze the strength of wind power accommodation and the total revenue of the system under three different modes of operation. At the same time, the environmental penalty cost is introduced in the specific operation mode, and the impact on the operation cost and the abandonment of the wind is analyzed, verifying the validity of the proposed model.
