Abstract: In order to improve the fault tolerance of the planned power grid and reduce the transmission loss rate, a frog leaping algorithm based distributed generation planning method for active distribution network is proposed. Considering the source load side fluctuation characteristics, a probability model is constructed to obtain the source load characteristics. Taking this as the input, probabilistic power flow calculation is carried out, and a bi-level programming model is constructed with opportunity constraints. Determine the upper power source location according to the probabilistic power flow calculation results. In order to improve the planning performance, the intermediate and acceleration factors are introduced to improve the frog leaping algorithm, so as to solve the lower level power configuration and realise the distributed generation planning of active distribution network. The results show that the proposed method has strong fault tolerance ability after planning, and the transmission loss rate is 5.8%. The longest planning time is 11.8 s.
