ベトナムの2050年ネットゼロに向け、固定料金・TOU・CPP・TOU-CPP複合の小売電力料金が需要柔軟性・系統コスト・排出・消費者厚生に与える影響をSWITCH 2.0で評価。TOU設計は系統コストを最大15%、CO2を17.2〜37.5%削減し厚生も改善。連続TOUブロックが有効でCPP追加効果は小さい。負荷の日中シフト可能割合に効果が強く依存し、送電混雑の再配分も生じる。
English
Using SWITCH 2.0 with an iterative demand-response module, this study evaluates flat, TOU, CPP, and hybrid TOU-CPP retail pricing for Vietnam's 2050 power system. TOU designs cut system costs by up to 15% and CO2 by 17.2–37.5% while raising consumer welfare; consecutive TOU blocks capture most benefits and CPP adds little. Benefits depend heavily on the share of shiftable load and reshape transmission utilization, supporting a staged TOU rollout with enabling technologies and coordinated grid planning.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも再エネ大量導入下での需要側柔軟性・ダイナミックプライシング設計は重要論点であり、TOUの段階導入や送電計画との整合という示唆は日本の電力システム改革・GX政策の参考になる。
In the global GX context
Adds quantitative evidence on demand-side pricing as a decarbonization lever in emerging Asian power systems, relevant to global debates on demand flexibility, renewable integration, and just transition finance.

📄 Abstract（原文）
Vietnam’s pathway to net-zero emissions by 2050 has so far relied primarily on large-scale renewable energy investments, with limited use of demand-side management. This study evaluates how alternative retail electricity pricing schemes - flat tariffs, Time-of-Use (TOU), Critical Peak Pricing (CPP), and a TOU-CPP hybrid - shape demand flexibility, system costs, emissions, consumer welfare, and reliability in Vietnam. The analysis uses SWITCH 2.0, an integrated capacity expansion and dispatch model with an iterative demand-response module, to Vietnam’s electricity system in 2050. Relative to flat pricing, the modeled TOU designs reduce total system costs by up to 15% and CO2 emissions by 17.2-37.5%, while increasing consumer welfare. Consecutive TOU blocks capture substantial benefits, whereas adding CPP produces little additional improvement. Endogenous block assignment achieves the lowest system cost and reduces storage investment, but does not yield the lowest emissions or highest consumer welfare. Sensitivity analysis confirms lower unit costs and emissions and higher consumer welfare under consecutive TOU than under matched flat-pricing cases across seven demand-response parameter combinations. However, the magnitude of these benefits depends strongly on the share of load available for within-day rescheduling. Demand shifting toward solar-rich hours also changes transmission utilization, relieving pressure on some corridors while increasing it elsewhere. The findings support a staged transition toward TOU pricing with simple consecutive blocks, accompanied by enabling technologies and coordinated transmission planning. The results represent conditional system-level outcomes rather than estimates of realized consumer responses or distributional effects.
