【摘要】：空调负荷的快速增长对电网的安全、经济运行影响较大。基于"电网友好"技术,提出空调负荷主动响应策略,并对其基本原理及实现方案进行详细论述。该策略的核心思想为:空调类设备根据电网电压的变化情况,短时间内主动调整自身的运行状态,以缓解电压变化对系统稳定运行造成的影响。通过搭建典型配电网算例,并建立适合暂态稳定分析的空调负荷聚合模型,对所提3种主动响应策略进行仿真验证,结果表明:空调负荷的分层分布式主动响应策略能够有效抑制电网电压产生的大幅波动,同时有效避免空调负荷响应对电网造成的冲击。电网友好型空调负荷的主动响应策略将有利于维持电网的安全稳定运行,同时也为实现用户与电网之间的友好互动提供一定的参考。
[Abstract]:The rapid growth of air conditioning load has a great impact on the security and economic operation of the power grid. Based on the "grid friendly" technology, the active response strategy of air conditioning load is proposed. The core idea of this strategy is: according to the change of grid voltage, the air conditioning equipment can adjust its running state actively in a short time. In order to mitigate the influence of voltage change on the stable operation of the system, a typical distribution network example is built, and an air conditioning load aggregation model suitable for transient stability analysis is established, and the three active response strategies proposed are simulated and verified. The results show that the layered and distributed active response strategy of air conditioning load can effectively restrain the large fluctuation of grid voltage. The active response strategy of grid friendly air conditioning load will help to maintain the safe and stable operation of the power grid. At the same time, it also provides a certain reference for realizing the friendly interaction between users and power grid.
