Abstract

Abstract:

According to the uncertainty of comprehensive decision-making and the strong subjectivity of index weight determining method in power transmission network planning, a comprehensive decision-making method for transmission network planning schemes was proposed based on the combined weight and cloud model. Firstly, based on the subjective weights calculated by analytic hierarchy process （AHP） and order relation method as well as the objective weights calculated by entropy method and variation coefficient method, the combined weight of each evaluation index was obtained by particle swarm optimization （PSO） algorithm, in order to remedy the insufficiency of experts assigned index weight and objective weight. Then the cloud model was adapted to determine the comprehensive evaluation results of each network planning scheme, which could fully reflect the fuzziness and randomness of index information. Finally, a simulation analysis of IEEE Garver-6 system was given to verify the effectiveness of the proposed decision-making method.

Key words: transmission network planning scheme, comprehensive decision-making, combined weight, cloud model, particle swarm optimization algorithm
