Optimal Scheduling of Integrated Energy Systems in Hydrogen-containing Parks Considering Dynamic Energy Efficiency

Taking full account of the complexity of energy supply equipment and load demand of the integrated energy system of the park, to promote the absorption of offshore wind power and reduce the operating cost of the park, this paper proposes a hydrogen-containing park energy cascade optimization method considering the dynamic energy efficiency model. First of all, in order to make the energy structure reasonably and make full use, the comprehensive energy system framework used by energy steps is established. Secondly, considering the operation efficiency of the equipment is affected by the load rate, environment and other related factors, in order to make the energy equipment flexibly respond to the load change, the dynamic efficiency model of the equipment is established. Finally, the optimal scheduling model is developed with the objective of minimizing the operational costs of the system, and its effectiveness and rationality are validated through simulation examples.
