Yardstick motivation evaluation method for investment of distribution network

Abstract

In the new situation of power development, such as the strengthening of incremental distribution business and the implementation of electric energy substitution strategy, with the same as the scale of investment and construction , the demand for upgrading and reconstruction of distribution network continue to increase. It is of great significance to study a set of reasonable and comprehensive evaluation model for medium and long-term dynamic planning investment of distribution network to guide the accurate investment of distribution network. We employ an index system for the investment efficiency of comprehensive performance of distribution network. An optimal combined weight selection model is built based on fuzzy hierarchical clustering analysis. The information entropy and time degree theory are introduced to the expected performance evaluation model of distribution network planning for establishing the dynamic yardstick evaluation method based on data envelopment analysis. Results are shown by analyzing of investment planning strategy of 9 regions in a province to verify the effectiveness and rationality of the proposed method.
