Evaluation method of investment strategy for distribution network equipment based on entropy weight-cloud model

Accurate investment in distribution network equipment is the key to ensure intensive and lean ma- nagement of power companies. At present, the evaluation information of distribution network equipment invest- ment plans tends to be arbitrary, and it is difficult to objectively evaluate and select the plan. This paper propo- ses an evaluation method for the investment strategy of distribution network equipment based on the entropy weight-cloud model. The cloud model and entropy method are thus used to calculate the evaluation index weights, to study the influencing factors such as economic benefits, technology and risks on investment strate- gies, to scientifically evaluate investment plans, and to provide support for data and references required for the for- mulation and optimization of investment strategies. Results of practice show that the method can identify the dif- ferences and weakness in the plan of the equipment investment of the distribution network and provide choices for the optimal decision-making. This research contributes to promoting the high-quality development of the distri- bution network and improving the proficiency of decision-making of the investment of the distribution network.
