| 摘要: |
| 为充分发挥温控负荷的调控潜力，以空调负荷为例，对空调负荷建模及集群控制策略进行了研究。首先从热力学模型与电气模型两方面建立了完善的空调负荷模型；其次考虑空调的启停次数以及使用寿命等实际因素，提出了一种基于改进温度优先序列的空调负荷集群群内控制策略；最后分析了负荷电压变化对集群响应功率的影响，基于频率下垂控制，提出了一种考虑功率响应偏差、电压约束以及集群等效荷电状态的空调负荷集群控制策略。基于MATLAB/Simulink的仿真结果表明，所提的空调负荷集群控制策略能够平抑微电网功率波动，同时能够有效降低空调的启停次数，减小对空调使用寿命的影响。 |

| Abstract: |
| In order to make full use of the regulating potential of the thermostatically controlled load, the air conditioning load is taken as an example to study the air conditioning load modeling and cluster control strategy. Firstly, a complete air conditioning load model is established from both the thermodynamic model and the electrical model. Secondly, considering the actual factors such as the number of start-stops and the service life of the air conditioner, a control strategy in the air conditioning cluster based on the improved temperature priority sequence is proposed. Finally, the influence of load voltage changes on the cluster response power is analyzed, and an air conditioning cluster control strategy considering power response deviation, voltage constraint and cluster equivalent state of charge is proposed based on frequency droop control. The simulative results based on MATLAB/Simulink show that the proposed air conditioning cluster control strategy can realize the suppression of power fluctuation of microgrid, at the same time it can effectively reduce the number of start-stops of the air conditioner and reduce the impact on the service life of the air conditioner. |
