本研究は中国の農村配電網における高圧縮太陽光発電導入時の電圧逸脱や投資収益性の課題に対し、3種類のマイクログリッド開発方式（従来型増強、蓄電池併設型、フレキシブル連系）を提案し、段階的政策シナリオ下での事業性を評価。支援的政策条件下で全方式がIRR8%超を達成し、フレキシブル連系方式が最大12.12%のIRRを示した。感度分析では投資コストと再エネ賦課金が主要因と特定。
English
This study evaluates three rural microgrid schemes (conventional upgrade, dynamic capacity with storage, and flexible interconnection) under progressive policy scenarios. Results show all schemes achieve IRR over 8% under supportive policies, with flexible interconnection reaching 12.12%. Sensitivity analysis identifies investment cost and renewable energy surcharge as critical factors. The framework guides context-appropriate microgrid pathways for local renewable consumption.

日本のGX文脈において
本論文は中国の農村マイクログリッドの政策シナリオ評価を提供。日本でもFIT終了後の再エネ地産地消や系統制約緩和の観点で参考になり、特に投資収益性分析のフレームワークは地域エネルギー事業者や自治体に示唆を与える。
In the global GX context
This paper presents a systematic techno-economic analysis of rural microgrids under market-oriented policies, relevant to global efforts in decarbonizing rural energy systems. It demonstrates how coordinated policy instruments (tariffs, ancillary services, grid deferral subsidies) can enable viable investments in distributed renewable energy, offering insights for countries with high PV penetration and grid constraints.

📄 Abstract（原文）
To address practical challenges arising from high-penetration photovoltaic (PV) integration into rural distribution networks—such as voltage violations and suboptimal investment returns—this study systematically evaluates the techno-economic feasibility of rural distribution transformer zone microgrids under the evolving landscape of electricity market reforms. Aligned with China’s “dual carbon” goals (carbon peak by 2030 and carbon neutrality by 2060), three representative microgrid development schemes are proposed: (1) conventional grid upgrading, (2) dynamic capacity enhancement (with energy storage), and (3) flexible interconnection. A progressive policy scenario framework is established, ranging from a baseline “PV-only” scenario to a comprehensive “full-benefit” scenario that incorporates preferential electricity tariffs, ancillary service market participation, and subsidies for deferring grid upgrades. Results indicate that under supportive policy conditions, all three schemes achieve financial viability, with full-investment internal rates of return (IRR) exceeding 8%. Notably, the flexible interconnection scheme yields the highest IRR of 12.12% in the full-benefit scenario. Sensitivity analysis identifies system-specific investment cost and renewable energy retail surcharge as the two most critical factors influencing project economics. This study provides a systematic analytical framework for selecting context-appropriate microgrid pathways in rural areas and underscores the pivotal role of coordinated policy and market mechanisms in enabling localized renewable energy consumption.
