doi:10.11930/j.issn.1004-9649.202402003

Abstract

Abstract:

The paper proposes an optimal scheduling strategy for the integrated energy system of an industrial park containing electric vehicle loads. First, based on the differences in load characteristics at different times and the differences in demand of electric vehicle users, a flexible charging and discharging model for electric vehicles is established. Second, the relevant hydrogen energy equipment model is established for the special hydrogen energy demand in the park. Then, the electric vehicle cluster, distributed photovoltaic and hydrogen equipment are integrated into the comprehensive energy system, and an integrated mathematical model is formed by the second-order cone relaxation process. Finally, the energy management and energy trading of the integrated energy system in an industrial park with solar photovoltaic and electric vehicle clusters are considered to further analyze its daily operation status. The results show that the proposed strategy can balance the operational benefits and risk-cost of the integrated energy system.

Key words: electric vehicles, integrated energy systems, optimal dispatching
