In allusion to economic-technical optimization objective of distribution network to which distributed generation (DG) is added, a mathematical model for multi-objective planning of DG is given. Integrating real-coded quantum generic algorithm with such multi-objective optimization strategies as non-dominated sorting, elite reservation and hierarchical clustering, a multi-objective chaotic quantum generic algorithm is proposed, and comprehensive planning research on installation sites and capacities of DGs is performed. Analysis on calculation results shows that the proposed algorithm possesses better performances in computational accuracy, convergence speed and searching ability than traditional multi-objective generic algorithms, thus it is available for reference to the implementation of multi-objective planning of DGs.
