Abstract


With the deepening degree of market power industry , power supply enterprises and users are increasingly concerned about the reliability of the electricity supply problem , and how to meet the reliability requirements under the premise distribution network planning project life cycle the economic and social benefits optimal distribution network planning priorities . This article summarizes results of previous studies on the basis of the widely read literature of domestic and international distribution network planning , in-depth study focused on the distribution network reliability and grid planning . Proceed from the point of view of the whole life cycle of the project of distribution network planning , distribution network planning throughout the life cycle of the project within the cost structure and calculation method , taking into account the distribution network , the power balance constraints established the reliability cost - benefit based distribution network structure of the whole life cycle cost planning mathematical models and optimal distribution of multi - particle swarm collaborative optimization algorithm to solve the mathematical model , come to the reliability and economy of sexuality coordination The mesh grid planning program . Analysis of the IEEE-RBTS example validate the correctness and feasibility of the proposed method , the article with full project life -cycle cost of the power grid planning factors that affect sensitivity analysis , further optimization of the distribution network planning projects the total life cycle cost guidance suggests Finally, we use Visual studio 2005 language software implementation of the proposed planning method . The proposed distribution network structure planning , coordination contradiction between the reliability and economy of the distribution network , and thus achieve an optimal balance between the two , building safe, reliable and economic operation of power distribution the network has important significance in theory and practice .
