在智能电网建设背景下,输电网投资面临各种潜在的市场风险,对投资决策的灵活性提出了较高的要求。应用技术成熟度理论分析智能输电网投资决策问题,根据技术成熟度等级划分智能输电网的有效投资阶段,建立基于技术成熟度的智能输电网多阶段投资决策模型,以确定最优投资方案及各阶段的投资资金数量。以IEEE-24节点系统为例分析考虑输电线路、晶闸管控制串联电容器补偿方案的3阶段智能输电网投资决策问题,验证了上述模型的正确性和有效性。
Under the background of smart grid construction, investment in transmission network faces various potential market risks and puts forward higher requirements on the flexibility of investment decisions. Applying the technology maturity theory to analyze the investment decision-making problem of smart grid, divide the effective investment phase of smart grid according to the level of technology maturity, and establish a multi-stage investment decision model of smart grid based on technology maturity in order to determine the optimal investment plan and each Phase of the investment funds. The IEEE-24 node system is taken as an example to analyze the investment decision-making of 3-phase smart grid considering the transmission line and thyristor control capacitor compensation scheme in series, which verifies the correctness and effectiveness of the above model.
