Supply-Demand Coordination of Wind-Solar-Hydrogen Integrated Energy System Considering Hydrogen Delivery

Abstract

Recently, more attention is attracted on renewable energy sources (RESs) that could alleviate energy and environmental issues. However, with the fast development of RESs, vast power curtailment arouses due to the mismatch of energy demand and renewable supply in time and spatial horizon, leading to low renewable energy sources utilization efficiency. In this paper, we propose a coordinated scheduling problem of a wind-solar-hydrogen integrated energy system (WSH-IES) to address the problem mentioned above. The curtailed RESs power can be converted into hydrogen in supply subsystem, and such hydrogen can be delivered to demand subsystem through tube trailers to meet multi-energy demand. The problem is formulated into a mixed integer linear programming problem. Numerical results show the developed method can achieve 100% RESs utilization efficiency and reduce 23.4% of the operation cost through the coordinated scheduling of all the energy devices and the hydrogen interaction between the demand and supply subsystems.
