Local Control Method for Distributed Power Sources with Lost Connection in Distribution Networks
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 gen-eration 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.
