A Decision-making Model on Stage Financing for Smart Transmission Grid Investment Based on Technology Readiness

Abstract Under the construction of smart grid, transmission grid investment is faced with many potential risks, and high flexibility of decision-making is asked. Based on technology readiness theory, stage financing issues for transmission grid investment are studied. Then transmission grid investment is divided into several stages, and in order to form an optimal investment scheme and find reasonable fund for each stage, a decision-making model for transmission grid investment based on technology readiness is established. The model is validated through three-stage transmission grid investment project in IEEE-24 bus system, to consider the optimal investment decision between transmission lines and TCSC devices.
