    摘要:

    调控空调负荷参与电网削峰填谷对于维持系统稳定运行、减少发电机备用容量提高效率,从而增大电网运行效益具有巨大潜力。基于家用分散式空调的工作原理,在MATLAB/Simulink环境下搭建了简化空调房调温模型,以该模型为基础依次探究了定/变频空调调温、增大变频区间调温的特性。考虑空调的工作特性,提出了一种对空调控制系统进行简单改造,使其自适应电网预测负荷大小进行互补运行的策略。最后开展基于RT-LAB实时仿真平台的模型仿真测试与试验,验证了仿真模型的正确性以及控制策略促进空调负荷参与调峰控制的有效性。

    Abstract:

    Controlling air conditioning load to participate in the power grid load shifting has great potential for maintaining stable operation of the system,reducing the reserve of generators,and improving the efficiency of the grid.Based on the principle of the household decentralized air conditioner,a simplified air conditioning room temperature adjustment model was built in the MATLAB/Simulink environment.Based on the model,the characteristics of the fixed/inverter air conditioner temperature adjustment and influence of adjusting frequency conversion interval were studied in turn.Considering characteristics of air conditioners,a strategy is proposed to conduct an adaptively complementary operation of the air conditioner according to grid load.Finally,the model simulation test based on RT-LAB real-time simulation platform is carried out,which verifies the correctness of the model and effectiveness of the strategy to participate air conditioners in peak shaving control.
