Fueled by industrial progress, a surge in fossil fuel consumption and carbon emissions has led to global warming, posing immense threats to global ecology, human health, and our survival. In response to this crisis, countries are actively pursuing the development of renewable energy alongside emissions reduction efforts, striving to achieve carbon neutrality. The integrated energy system (IES), an emerging technology, integrates various energy systems (such as ORC, OFC, HP, thermal storage, etc.) and energy forms (electricity, heating, cooling, gas, etc.) on the user side to achieve energy savings and emission reduction. By efficiently managing different energy forms to meet user needs, IES improves overall efficiency, reduces costs, and minimizes emissions, solidifying its position as a key driver of the energy transition.

Driven by the need for sustainability and resilience, research in integrated energy systems aims to optimize overall energy efficiency, reliability, and environmental impact. Shifting the focus from single energy sources to interconnected systems, this research addresses factors such as:

• Integrated energy system planning issues: Analyzing the energy requirements of users and regional energy resources to develop realistic planning strategies.
• Integrated energy system operation scheduling issues: Ensuring the integrated energy needs of users are met.
• Integrated energy system multi-energy subject trading issues.
• Integrated energy system benefit assessment issues.
• Integrated energy system business model issues: Taking into account the interests of government, society, enterprises, and users in the operation process.
• Coupling of organic Rankine cycles to integrated energy systems.

This study focuses on the optimization of planning, operation, market trading, and benefit assessment in integrated energy systems to achieve enhanced energy efficiency, reliability, reduced operating costs, and minimized carbon and pollutant emissions. The scope of this research topic includes, but is not limited to, the following themes:
• Load forecasting methods.
• Energy operation scheduling methodology.
• Simulation of market transactions in integrated energy systems.
• Simulation of integrated benefit assessment for integrated energy systems.
• Simulation of the operational performance of integrated energy system equipment.
• Life Cycle Assessment (LCA): Assessing the environmental impacts of integrated energy systems throughout their life cycle.
• Integrated energy system analysis and optimization.
