Peer-to-peer home energy management incorporating hydrogen storage system and solar generating units.

The peer-to-peer (P2P) energy management in the buildings is modeled and studied by this paper. In the proposed P2P home energy management, the buildings share their energy resources with each other to supply their demands. Three individual buildings are considered, two buildings are equipped with solar panels and the other building is equipped with hydrogen storage unit. The buildings are connected to each other by power lines for P2P operation. The uncertainty of loads and solar energy are incorporated and the model minimizes the cost of solar unit, power lines, fuel-cell, electrolyzer, and storage tank. The optimization problem finds optimal power of solar system, power lines, fuel-cell, electrolyzer; optimal capacity of hydrogen storage tank; and optimal operation pattern (charging-discharging regime) of hydrogen storage system. The results demonstrate that P2P operation helps the buildings to benefit from their energy resources. • Peer-to-peer home energy management is presented to minimize the costs. • Buildings are equipped with solar units and hydrogen storage system. • Buildings share their energy resources with each other as peer-to-peer operation. • Uncertainty of load and solar energy is handled by stochastic programming. • Optimal sizing and operation are found for hydrogen storage and solar systems.
