Abstract
With the liberalization of incremental distribution network investment business, more and more investment projects from various sources and diversified ownership are eligible for construction applications. This article proposes a many-criteria investment priorities evaluation method for incremental distribution network planning based on the hyperplane projection transformation. In the established many-criteria evaluation indicator system, the multi-grade indicators including economic and technical factors are adopted to comprehensively evaluate the distribution network infrastructure projects. Furthermore, the hyperplane projection transformation is applied to project the solutions from the many-objective hypercube to the normalized hyperplane. Then, the comprehensive distance quantifies the quality and balance of the distribution network infrastructure project indicators, and the investment priority rankings can be obtained. Finally, the performance of the proposed method is validated on six distribution network infrastructure projects with eleven evaluation indicators. The results show that the proposed many-criteria evaluation of infrastructure investment priorities is effective to recognize the non-dominance solutions with extremely good or extremely poor indicators.
Highlights
With the implementation of incremental distribution network planning, many problems in the distribution network, such as the poor quality of power supply and serious security risks, have been improved [1]
More and more investment projects from various sources and diversified ownership are eligible to participate in the construction of incremental distribution network
This research aims to investigate the many-criteria investment priorities evaluation method for incremental distribution network planning considering both the quality and balance of the project indicators, which is based on the hyperplane projection transformation
Summary
With the implementation of incremental distribution network planning, many problems in the distribution network, such as the poor quality of power supply and serious security risks, have been improved [1]. More and more investment projects from various sources and diversified ownership are eligible to participate in the construction of incremental distribution network. Compared with the traditional distribution network investment, the incremental distribution network planning should guarantee the safety and reliability of the grid, and take into account the economy and efficiency of the distribution network operation due to the participation of the social capital [1], and more evaluation indicators are needed when evaluating incremental distribution network construction projects. The existing methods mainly use TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) or improved TOPSIS to prioritize distribution network infrastructure projects. TOPSIS cannot recognize the extreme non-dominance solutions with extremely good or VOLUME XX, 2020
