Modeling and Optimization of Integrated Energy System for Renewable Power Penetration considering Carbon and Pollutant Reduction Systems

Abstract

To address climate change and environmental pollution, an increasing number of renewable energy source generations are connected to the grid; meanwhile, the need for carbon capture and pollutant reduction for traditional energy has increased in urgency. In this study, the dispatch problem for an integrated energy system (IES) is expanded considering renewable penetration, carbon capture, and pollutant reduction. First of all, detailed models of carbon and pollutants reductions systems are set up. Specifically, the carbon capture system’s characteristics, which contribute more flexibility for the conventional power plants, are clarified. In addition, the treatment process of pollutants containing SO2 and NOx is elaborated. Moreover, the structure of an evolutionary IES containing pollutants treatment, battery and thermal energy storage, and carbon capture and storage systems are put forward. On this basis, the model of IES for renewable energy penetration and environmental protection considering the constraint of pollutant ultra-low emissions is set up. Finally, the simulation results show that the proposed approach can improve renewable energy penetration and restrain carbon and pollutants emissions.

Automated deep reinforcement learning for real-time scheduling strategy of multi-energy system integrated with post-carbon and direct-air carbon captured system

“…The obtained results show that nearly 100% carbon capture of the liquified natural gas plant is possible with 1.69$/h reduction in total cost. The optimal dispatch of MES was examined by G. Zhang et al [17] by utilising the carbon capture by PCC for sync gas production via power-to-gas (P2G) technology and power generation by supercritical CO2 (S-CO2) cycle; the carbon emission of the system was reduced by 89.5% with 1% increase of the energy efficiency. In Berge et al [18], PCC was coupled with P2G to achieve a low-carbon economy of MES.…”

Review on low carbon planning and operation of integrated energy systems

“…The proposed models in [49,50] need to solve nonlinear programming problems, which are suitable for solving by invoking the convergent and robust interior point method (IPOPT) in GAMS. In [51], the fmincon solver in MATLAB is called to solve the optimal scheduling of IES for economic and environmental benefits, a nonlinear optimization problem.…”

Two stage robust planning of park integrated energy system considering low carbon

“…On carbon capture, Zhang et al (2021) established the features of the carbon capture system, which contributes greater flexibility for the conventional power plants, and expanded the dispatch issue for an integrated energy system (IES) integrating renewable penetration, carbon capture, as well as emission reduction. Ma et al (2021) introduced carbon capture systems in conventional IES, and carbon source of P2G comes from carbon emissions from cogeneration units.…”
