摘要
为保证配电网的稳定运行,研究考虑通信时延的配电网失联分布式电源就地控制方法。通过分布式电源接入的时序特征,建立分布式电源失联状态就地控制函数;以考虑通信时延为基础,在配电网整体平衡的前提下,确定配电网系统的最大功率差值;将最小风险作为控制边界,通过差值插值注入弥补失联分布式电源的波动电压,实现配电网失联分布式电源就地控制。实验结果表明,应用新方法就地控制后可以实现电压的稳定,具有较高的应用价值。
To ensure the stable operation of the distribution network,a local control method for disconnected distributed power generation in the distribution network considering communication delay is studied.Establish a local control function for the disconnected state of distributed power sources based on the temporal characteristics of their access;based on the consideration of communication delay and under the premise of overall balance of the distribution network,determine the maximum power differences of the distribution network system;by using the minimum risk as the control boundary and injecting difference interpolation to compensate for the fluctuation voltage of the disconnected distributed power generation,local control of the disconnected distributed power generation in the distribution network is achieved.The experimental results indicate that the application of the new method for on-site control can achieve voltage stability and has high application value.
