本研究は、変動性再生可能エネルギー（VRES）の統合に伴う出力抑制問題に対処するため、Power-to-Heat（PtH）技術と地域暖房システム（DHS）を組み込んだ長期電源開発モデルを開発した。ウクライナの電力系統とDHS需要を対象に2040年までのシミュレーションを実施し、非暖房期に余剰電力をPtH電気ボイラーで熱に変換することで、天然ガス火力を代替し電力と熱の脱炭素化が可能であることを示した。
English
This study develops a long-term generation capacity expansion model integrating Power-to-Heat (PtH) and district heating systems to mitigate renewable curtailment. Applied to Ukraine's power system through 2040, results show that PtH electric boilers can convert excess wind and solar power into heat during non-heating seasons, displacing natural gas and decarbonizing both electricity and heat supply.

📄 Abstract（原文）
The growing integration of variable renewable energy sources (VRES) challenges power system flexibility and may cause curtailment due to excess capacity, grid constraints, or operational and market factors. Power-to-Heat (PtH) technology can mitigate these issues by coupling electricity and district heating sectors, providing additional flexibility and supporting decarbonisation. This study develops a long-term generation capacity expansion model that integrates PtH and district heating system (DHS) operation to achieve balanced VRES penetration. The model includes DHS heat demand balances and links electricity and heat via thermal power plants, combined heat and power (CHP) plants, and PtH units. The methodology is applied to Ukraine’s Integrated Power System and district heating demand through 2040, employing typical daily load profiles discretised into six four-hour segments. Results demonstrate the feasibility of deploying PtH electric boilers during the non-heating season, when high RES and inflexible nuclear generation create surplus electricity. These boilers convert excess wind and solar power into thermal energy for district heating, displacing natural gas-fired technologies and simultaneously decarbonising electricity and heat supply.
