Optimal Dispatching Model of Integrated Energy System Considering Power to Gas and Carbon Capture System

Abstract

In order to improve the renewable energy consumption capacity and carbon emission benefit of park-level integrated energy system (PLIES), an optimal dispatching model including coupled power to gas (P2G) and carbon capture system (CCS) is proposed. Firstly, a coupling model of P2G and CCS is established, and the coupling model is introduced into PLIES with gas-fired cogeneration as the main unit. Secondly, taking the lowest economic operating cost as the objective function, a PLIES low-carbon economic dispatching model with coupling P2G and CCS is constructed. Finally, this paper takes an industrial park in the north as an example and sets two different scenarios for example analysis. The simulation results show that the proposed model can effectively reduce emissions and achieve efficient utilization of renewable energy.
