Proposes a holistic multi-timescale framework for remote wind-PV bases linked via VSC-HVDC that co-produce green hydrogen. A two-stage stochastic model co-optimizes capacity and 15-min dispatch under frequency-security constraints, paired with communication-free coordinated control of BESS, electrolyzer, wind and PV. Case study yields LCOE of 0.2901 CNY/kWh (0.0227 lower with electrolyzer) and satisfies frequency limits across 1,152 operating points.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では北海道・東北の遠隔再エネ基地と海底直流連系、余剰電力の水素転換が政策的焦点。本枠組みは弱連系系統での周波数確保と水素併産の経済性を両立する設計論として、国内の系統計画・水素拠点構想に示唆を与える。
In the global GX context
As grids integrate remote renewables via HVDC and pursue green hydrogen, frequency security becomes a coupled planning-control problem. This work offers a template for co-optimizing storage, electrolyzers and converter controls under frequency constraints, relevant to global energy-transition and grid-connection debates.

📄 Abstract（原文）
Remote-area wind–photovoltaic bases are increasingly connected to load centers through voltage-source-converter high-voltage direct-current (VSC-HVDC) links and are expected to co-produce green hydrogen. In such systems, weak interconnection, frequent transitions between grid-connected and islanded operation, and converter-dominated dynamics make frequency security a coupled planning-and-control problem rather than a pure control-tuning problem. This paper proposes a holistic multi-timescale framework for a remote-area renewable energy system comprising wind turbines (WTs), photovoltaic (PV) units, battery energy storage systems (BESSs), electrolyzers (ELs), and a VSC-HVDC link. A two-stage stochastic model co-optimizes capacity configuration and 15-min dispatch under scenario-dependent frequency-security constraints, and a coordinated control strategy combines communication-free DC-link-voltage-based frequency perception with constraint-aware support from BESS, EL, WT, and PV. In the case study, the optimal scheme yields an LCOE of 0.2901 CNY/kWh, and introducing EL reduces the LCOE by 0.0227 CNY/kWh compared with the scheme without EL. Time-domain simulations across three operating scenarios and 1,152 steady-state operating points, with 1,000 disturbance realizations per point, show that the proposed framework satisfies the prescribed frequency-security limits in all tested cases and improves the sending-end frequency nadir relative to the benchmark controllers. The results demonstrate that coordinated use of hydrogen load, battery storage, and VSC-HVDC can simultaneously improve economic performance and frequency security in remote-area renewable energy systems.
