中国のデュアルカーボン目標達成に向け、SWITCH-Chinaモデルで揚水発電（PHS）と蓄電池（BESS）の長期導入経路を最適化した研究。2050年までに蓄電設備は1000〜1200GW、エネルギー容量2220〜3340GWhに達し、PHSが初期・中期、BESSが後期の導入を主導する。地域差が顕著で、華北が最大、東北が最小の需要を示す。
English
Using the SWITCH-China model, this study optimizes long-term deployment pathways for pumped hydro (PHS) and battery storage (BESS) under China's dual-carbon targets. By 2050 storage reaches 1000–1200 GW (2220–3340 GWh), with PHS leading early-mid transition and BESS driving later expansion. Deployment shows strong regional heterogeneity, with North China requiring the most and Northeast the least.

日本のGX文脈において
中国の蓄電インフラ計画は、日本の系統用蓄電池・揚水発電政策や再エネ大量導入時の柔軟性確保の議論に参照価値がある。地域別最適化の手法は、日本国内の電力系統・地域間連系の議論にも応用可能。
In the global GX context
This adds to global power-system decarbonization scholarship by quantifying storage-mix pathways and regional heterogeneity at provincial grid level, relevant to flexibility planning under high VRE shares. It complements TCFD/transition-finance discussions on grid infrastructure investment needs.

📄 Abstract（原文）
The power system transition is central to achieving China's dual‑carbon targets of carbon peaking by 2030 and carbon neutrality by 2060. The rapid expansion of variable renewable energy (VRE) has made pumped hydro storage (PHS) and battery energy storage systems (BESS) critical flexibility resources for integrating high shares of VRE and supporting power system balancing. This study is motivated by the need to coordinate PHS and BESS development with China's evolving regional flexibility requirements. This study employs the SWITCH-China model, a linear programming framework that integrates long-term capacity expansion and short-term operational dispatch. The model optimizes energy storage deployment pathways across alternative development scenarios by minimizing total system cost, including investment, operation, and transmission costs, while accounting for regional power demand, carbon emission constraints, and power system operational constraints. The results show that by 2050, China's installed energy storage capacity reaches 1000–1200 GW, with an energy capacity of approximately 2220–3340 GWh. PHS leads energy storage expansion in the early and middle stages of the transition, whereas BESS becomes the main driver of additional deployment in the later stage. Energy storage demand also exhibits pronounced regional heterogeneity: North China requires the largest deployment, while Northeast China requires the least, reflecting differences in VRE resource endowments, load-balancing pressure, and interregional power transmission. At the provincial grid level, PHS mainly provides capacity support and sustained regulation, whereas BESS is better suited to short-duration balancing and flexible system regulation. This study offers policy-relevant insights into the coordinated deployment and operation of storage technologies during China's power system transition.
