摘　　要：随着我国风电装机容量的增加,风电消纳给电网的安全稳定运行带来了新的挑战。以空调为主的热控负荷与电网互动友好,正越来越多地参与到电力系统的调度中。为实现变频空调负荷与现有调度模型的兼容,使空调负荷能平滑风电功率波动,提出了一种基于风电消纳场景下的空调负荷建模方法以及相应的调控策略,将变频空调建立成热电池模型,利用分层分布控制方法进行调控,实现微观层面热电池的有效控制。结果表明:所提出的热电池模型可以有效描述变频空调负荷的储能特性,实现变频空调负荷与系统现有调度模型的兼容,提出的调度和控制策略能够有效调控变频空调负荷以提高系统风电消纳能力。With the increase of installed capacity of wind power in China,wind power consumption brings new challenges to the safe and stable operation of power grid.Air conditioning based thermal control load and power grid are interactive and friendly,and are more and more involved in the power system scheduling.In order to realize the compatibility between the variable frequency air conditioning load and the existing scheduling model,and make the air conditioning load smooth the wind power fluctuation,this paper proposes an air conditioning load modeling method and the corresponding regulation strategy based on the wind power consumption scenario.The variable frequency air conditioning is built into a thermal cell model,and the hierarchical distribution control method is used to achieve the effective control of the micro level thermal cell.The results show that the proposed thermal battery model can effectively describe the energy storage characteristics of the variable frequency air conditioning load,realize the compatibility of the variable frequency air conditioning load and the existing scheduling model of the system,and the proposed scheduling and control strategy can effectively regulate the variable frequency air conditioning load to improve the wind power consumption capacity of the system.
