Rationality Evaluation of Transmission Line Planning Based on Combination Weighting Method and Cloud Gravity Center Evaluation Method

An evaluation method of transmission line planning rationality based on combination weighting method and cloud center of gravity evaluation method is proposed. The method first uses principal component analysis and analytic hierarchy process to solve the weight values of its assessment indexes; And the weighted deviation degree is used to measure the degree of the system state change, so as to determine its reasonableness level. Through cloud modeling, a mathematical model that can deal with uncertainty and stochasticity want to combine stochasticity and random numbers to be able to better reflect the reality of complex systems. Therefore the cloud-centered method can better integrate the ambiguity and randomness in the assessment information and ensure the scientificity of each weighting result. The experimental results show that the proposed state evaluation method based on combination weighting method and cloud gravity center evaluation method can effectively evaluate the rationality of transmission lines.
