| Abstract |
This paper proposes a sector-coupling-based optimal operation scheduler for community multi-energy systems integrating electricity, heat, and hydrogen. The proposed method considers photovoltaic generation, ESS, electrolyzers, fuel cells, heat pumps, boilers, electric water heaters, absorption chillers/heaters, and thermal storage tanks in a unified framework, while reflecting both building-specific domestic hot water operation and community-shared cooling, heating, and power resources. An integrated objective function and operational constraints are designed by considering time-of-use electricity tariffs, seasonal gas prices, storage limits, thermal tank temperature bounds, and peak power constraints. In addition, a power-priority-based correction logic is introduced to satisfy actual energy balance conditions. Simulation results show that the proposed scheduler satisfies domestic hot water temperature requirements, economically allocates thermal and electrical resources, and improves renewable energy utilization and operational efficiency. |
