Abstract:Due to the situation that the distribution network lacks efficient cluster division strategy for the optimization of distributed active power flow, this paper optimizes and improves the distribution network cluster division strategy based on genetic algorithm.First of all, considering the limited computing capacity of the terminal in the distribution network area and the condition that the strength of each cluster must meet the standard, the node limit index of cluster division is defined to make the result of cluster division more reasonable.Then, the mechanism of genetic algorithm is improved, the convergence speed of genetic algorithm is improved, and the global optimization ability is enhanced.Finally, simulations are carried out on IEEE-33 nodes system on MATLAB simulation platform to verify the rationality of the proposed index and the effectiveness of the improved algorithm.
