Distributed generation (DG) technology has been rapidly developing and the DG penetration level is becoming higher and higher in power system distribution network in recent years. Due to the access of multiple distributed generators, the traditional instantaneous overcurrent protection may fail to coordinate with each other. In order to solve this problem, this paper studies the fault characteristics...
In order to adapt to the requirement that distribution network has limited measurement devices; a distribution network state estimation algorithm based on finite measurement information is proposed. In the model, distribution network node voltage amplitude and voltage phase work as state variables, and measured node information and load planning data work as real measurement and pseudo measurement...
