Abstract

Abstract:

Power grid business is in a critical period of transformation from traditional business to emerging business. Due to the diversity of grid business development, the interplay between businesses should be considered to accurately quantify the investment value of businesses. This paper analyzes the coupling effect between businesses, constructs an evaluation system of business coupling effects to quantify the degree of grid business coupling through Choquet fuzzy integral, constructs an evaluation system of grid business investment value suitable for the new environment of future development, and constructs an optimization model of grid business portfolio investment taking into account the coupling effects. In the case study, the portfolio investment value, covering the comprehensive energy business, energy storage business and electric vehicle business, is 2.024, ranking the highest, among which, the basic investment value of business is 1.87 and the coupling investment value is 0.154. The case study verifies the necessity to consider the grid business coupling and the applicability of the investment optimization model. The results of this study can provide a support for the grid company to make the grid business portfolio investment decision.

Key words: power grid business, coupling, Choquet fuzzy integral, investment value, investment optimization
