摘要
为解决中国北方地区严重弃风问题,考虑通过储热装置解耦热电机组"以热定电"特性,通过电锅炉增大负荷侧用电负荷来提高风电消纳能力。以系统总经济成本最小和弃风量最少为目标函数,建立了含热电机组、火电机组、风电机组、储热装置以及电锅炉在内的多目标风电消纳协调调度模型。算例分析表明:所提模型有效,储热装置和电锅炉的联合调度,使得弃风时刻机组电出力明显减小,弃风状况得到改善,进一步验证了储热装置和电锅炉对于风电消纳的促进作用。
In order to solve the abandoned wind power issue during the heating period in winter in north China, considering the fact that the heat storage device could be used to decouple the ＂electrothermal coupling＂ of the thermoelectric unit and the electric boiler be used to increase the electric load on the load side, the accommodation ability of the grid wind power can be improved. Therefore, based of the wind power accommodation model, a multi-objective combined dispatch model of wind power accommodation containing thermoelectric unit, thermal power unit, wind power unit, beat storage device and electric boiler, is established. The model consists of the heat storage device at the power supply side and electric boiler at the load side, and takes the minimum economic cost of the system and minimum abandoned wind power as the fitness function. Finally, case study verifies that the effectivity of the proposed model. The combined dispatching model of the heat storage device and electric boiler makes the output power of the thermoelectric unit reduce obviously during the wind power abandoned time; what＇ s more, the promotion of the wind power accommodation condition is also verified.
