基于模糊PID的配电网多设备运行协同控制研究

Fuzzy PID-based Multi-equipment Collaborative Control for Distribution Networks

当多个设备在配电网中独立运行时,它们可能会因缺乏统一的调度和控制而出现相互干扰,进而导致系统电压稳定性差,因此提出基于模糊PID的配电网多设备运行协同控制研究。通过协调配电网中多个设备的功率,实现整个配电网的高效稳定运行,同时利用模糊PID控制方法对配电网节点功率进行实时修正,以应对电网中的不确定性和复杂性。为了确保协同控制的有效性和可行性,明确配电网多设备运行协同控制的约束条件,并基于多目标优化方法,实现配电网多设备的协同控制,优化整个配电网的运行性能。实验结果表明,该方法能有效协同控制配电网多设备同时运行,并保持系统电压的稳定,为电力系统的可持续发展提供了有力支持。

When multiple equipment operate independently in a distribution network,they may interfere with each other because of the lack of unified scheduling and control,which will lead to poor voltage stability of the system.Therefore this work focused on multi-equipment cooperative control based on fuzzy PID.By coordinating the power of multiple equipment,the efficient and stable operation of the whole distribution network was achieved.At the same time,the power of distribution network nodes was corrected in real time by using fuzzy PID control to cope with network uncertainty and complexity.In order to ensure the effectiveness and feasibility of cooperative control,the constraint conditions of multi-equipment cooperative control were determined,and the cooperative control was realized by multi-objective optimization,facilitating optimized operation performance of the whole network.The proposed method was indicated by experiment capable of effectively controlling the simultaneous operation of multiple equipment in the distribution network and maintaining the stability of the system voltage,which provides strong support for the sustainable development of the power system.
