At present, the large-scale development of renewable energy is restricted by the absorption problem. The electric-hydrogen technology becomes a new flexible resource for coupling electric energy, heat energy and other kinds of energy by absorbing abandoned electricity. The lack of flexibility in a power system with high proportion of intermittent renewables can lead to issues like large-scale curtailment of wind and solar, uneconomic energy system operation; even endanger the security of energy supply. As a new flexible resource, power-to-hydrogen technology has received widespread attention and also requires a comprehensive assessment. The electricity-to-hydrogen technology has become a new flexible resource for coupling electric energy, thermal energy and other energy sources by absorbing and discarding electricity. To this end, this paper proposes a multi-dimensional system value evaluation method for the power-to-hydrogen (P2H) technology, the collaborative planning of large-scale electric-hydrogen resources in the new power system is an important issue in this study. The method, based a fuzzy analytic hierarchy process, delivers a multi-dimensional index that involves a P2H’s flexibility, ability to consume intermittent renewables, economy and environmental value. The system value of P2H and the effectiveness of the proposed algorithm are demonstrated by a use case study. The effects caused by P2H capacity variation are quantified, and an optimal capacity of P2H was found. |
