Integration of Demand Response and Hydrogen Storage System in Security Constrained Unit Commitment With High Penetration of Wind Energy

The increase of energy consumption, environmental pollution and limit of energy sources have led to the increasing integration of variable renewable energy sources specifically wind energy. The uncertain nature of these sources has aggravated the imbalance between electricity supply and demand. Wind power management could be a suitable solution to solve imbalance by converting excess wind energy into hydrogen and store for later use via hydrogen-based gas turbines. Integration of demand response (DR) could decrease system energy cost and improve reliability of the system. This paper proposed a security constrained unit commitment (SCUC) with high penetration of wind energy considering coordinated operation of demand response and hydrogen storage system. The proposed model has been tested on a 6-bus system. The results show reduction on wind curtailment and system operation cost.
