A Study of Investment Decision Making in Grid Business Portfolio Considering Risk and Coupling Effect

Aiming at the challenges of increasing diversification of grid business and intensifying uncertainty of investment risk, this paper proposes an investment decision model for grid business portfolio considering risk and coupling effect. On the basis of assessing the value of a single business, the model further quantifies the coupling value generated by multibusiness synergy, and accordingly constructs a dual-objective optimization model with the highest total contribution of the business portfolio and the lowest total risk level of the business portfolio, and adopts a quantum multi-objective genetic algorithm for model solving, and the results of the case study validate the model and its solving algorithm.
