本論文は、米国本土の電力システムを対象に、2050年までの容量拡大モデルを構築し、静的同期直列補償装置（SSSC）の最適導入を評価した。SSSCは送電線の混雑緩和に有効で、年間19億ドルのコスト削減または20%の送電拡大削減が可能であり、中西部での風力発電の東部への送電に特に有効である。脱炭素化政策の強化や需要増加下でその価値は高まる。
English
This paper develops a capacity expansion model for the contiguous U.S. power system toward 2050, incorporating Static Synchronous Series Compensators (SSSC). SSSCs reduce annualized system costs by $1.9 billion or decrease transmission expansion requirements by 20%, with benefit-cost ratios of 59 in the Midwest, facilitating wind power delivery. The value increases under higher demand growth and stricter decarbonization policies.

📄 Abstract（原文）
Flexible AC Transmission Systems (FACTS), particularly Static Synchronous Series Compensators (SSSC), can improve network transfer capability and complement restricted transmission expansion. Evaluations of FACTS within large-scale, real-world power system planning are currently lacking. This paper develops a capacity expansion model for the contiguous U.S. power system toward 2050, incorporating SSSC-modified linear power flow equations and accounting for impedance feedback in transmission expansion. Cost-optimal system expansion leverages widespread nationwide SSSC deployment on small-to-medium capacity lines and reduces the number of corridors to be reinforced. Overall, SSSCs reduce annualized system costs by $1.9 billion or decrease transmission expansion requirements by 20%. The most advantageous deployments achieving benefit-cost ratios of 59 concentrated in the Midwest, facilitating the delivery of central U.S. wind power to eastern load centers. The value proposition of SSSCs is robust to cost sensitivities and potential competition from HVDC network expansion, and increases under higher demand growth and more stringent decarbonization policies. These findings provide a blueprint for leveraging SSSC deployment in the U.S. power system.
