非プログラム可能な再生可能エネルギーの増加に伴う系統混雑や逆潮流を緩和するため、PEM電解槽・水素貯蔵・燃料電池からなるPower-to-Hydrogenプラントの最適規模を線形最適化で検討。737kWの電解槽導入で年間逆潮流を81.61%削減し、変圧器と配電線の損失も低減。投資コストと水素販売収益を考慮した経済性評価も実施。
English
This study optimizes the sizing of a Power-to-Hydrogen plant (PEM electrolyzer, hydrogen storage, fuel cell) to mitigate reverse power flows in a distribution network with high PV penetration. A linear optimization model minimizes reverse flows while considering investment costs and hydrogen sales revenue. Results show an 81.61% reduction in annual reverse power flows with a 737 kW electrolyzer, also reducing transformer and feeder losses by 17.32% and 29.25% respectively.

📄 Abstract（原文）
The increase in power generation facilities from nonprogrammable renewable sources is posing several challenges for the management of electrical systems, due to phenomena such as congestion and reverse power flows. In mitigating these phenomena, Power-to-Gas plants can make an important contribution. In this paper, a linear optimisation study is presented for the sizing of a Power-to-Hydrogen plant consisting of a PEM electrolyser, a hydrogen storage system composed of multiple compressed hydrogen tanks, and a fuel cell for the eventual reconversion of hydrogen to electricity. The plant was sized with the objective of minimising reverse power flows in a medium-voltage distribution network characterised by a high presence of photovoltaic systems, considering economic aspects such as investment costs and the revenue obtainable from the sale of hydrogen and excess energy generated by the photovoltaic systems. The study also assessed the impact that the electrolysis plant has on the power grid in terms of power losses. The results obtained showed that by installing a 737 kW electrolyser, the annual reverse power flows are reduced by 81.61%, while also reducing losses in the transformer and feeders supplying the ring network in question by 17.32% and 29.25%, respectively, on the day with the highest reverse power flows.
