Abstract
With a high proportion of renewable energy connected to the Integrated energy system(IES), the dispatching optimization problem of the IES is particularly important. A reasonable dispatching strategy not only enables the economic operation of the IES, but also maximises the consumption of renewable energy. This paper is a study of IES with electrical, thermal, cold and hydrogen loads. Aiming at the minimum operating cost of the IES, a day-ahead dispatching optimization model of the IES is established. The power of all devices in the IES is optimised in real time, taking full account of their own constraints and the energy balance constraints in the IES. Finally, the model is solved by CPLEX and the effectiveness of the proposed IES day-ahead dispatching strategy is verified by simulation analysis.
