【 摘 要 】

The technology of multi-energy supply and energy storage can both improve the efficiency of energy use and the renewable energy absorption capacity of system, in which way they have wide application prospects. Based on the actual data of a park in East China, an integrated energy microgrid containing CCHP system and energy storage was modelled, in which the nonlinear characteristics of each equipment in the CCHP system, the investment cost and the maintenance cost were taken into consideration. With the objective function to minimize the total cost, an optimal economic operation model of the integrated energy microgrid was established. Finally, an example was given to demonstrate the economic benefits and the effect of improving the renewable energy absorption capacity brought by the introduction of multi-energy supply and energy storage.
