In the quest to align with China’s ambitious “carbon peaking and carbon neutrality” goals, researchers are delving into innovative strategies to enhance the low-carbon operations of integrated energy systems. A recent study, published in the journal *Measurement and Control* (originally *Diance yu yibiao*), offers a compelling approach to optimizing these systems, particularly those centered around thermal power.
Led by Liu Jiangtao of Nanjing Power Design Institute Co., Ltd., the research focuses on the operation and configuration of electric-thermal multi-energy complementary integrated energy systems. The study takes into account the costs associated with carbon capture and carbon trading, factors that are increasingly critical in the energy sector.
Liu Jiangtao explains, “Our goal was to establish a coupling model that considers carbon capture and installation, which is essential for improving the low-carbon operation capacity of these systems.” The research team developed detailed models for power networks and thermal networks, incorporating unit costs, carbon transaction costs, and new energy disposal costs. They also considered network operation constraints, using a modified IEEE 33-node distribution network and a 6-node thermal network for their analysis.
The study’s findings highlight the significant impact of heat network modeling, carbon trading prices, and carbon capture costs on the operation and configuration of integrated energy systems. Notably, the research identifies the marginal carbon price and carbon capture installation costs that could enhance system revenue, providing valuable insights for the energy sector.
“This research offers a practical reference for the construction and operation of integrated energy systems under the ‘dual-carbon’ background,” Liu Jiangtao adds. The implications of this work are far-reaching, as it could shape future developments in the energy sector, particularly in regions relying heavily on thermal power.
As the energy sector continues to evolve, the integration of carbon capture and trading mechanisms into operational strategies will be crucial. This study not only advances our understanding of these processes but also provides a roadmap for achieving more sustainable and economically viable energy systems. The insights gained from this research could influence policy decisions and commercial strategies, ultimately driving the transition towards a low-carbon future.
