Stochastic evaluation of impact of power to gas unit presence on energy hubs network management

Energy hub concept has provided new opportunities in energy management scope. Additionally, largely implementation of renewable energy resources has posed strict challenges in energy systems coordination issue. Probabilistic outputs of renewable energy sources make the energy provision coordination so complicated, in the regions where their penetration is high. Energy storage system can be proposed as a solution for mentioned problem. Power to gas units as an electrical energy storage can store the electrical energy in natural gas grid. This paper has focused on stochastic optimization of renewable based networked hubs in the presence of power to gas unit with economical target. Power to gas unit’s direct hydrogen injection and hydrogen tank facilities have been considered in this paper, as well. This paper demonstrates that, power to gas unit can participate positively in network cost and renewable energy curtailment reduction, considerably.
