Summary: This paper presents the development and application of an urban building energy simulation model to analyze a 5GDHC network, investigating its potential for sector coupling. A multi-model dynamic simulation was used to calibrate and optimize the operation of the network based on monitoring data. The study focused on flexibilities and cost optimization in heat production through different heating setpoint control strategies.

Summary: This study analyzes the cost-optimal pathway for transitioning from the current fossil-fuel based energy system to 100% renewables. Using different spatial resolutions and coupling configurations, the study investigates 12 scenarios for Chile's energy system. The results show that a multi-node, interconnected, and fully sector-coupled energy system is the most optimal solution for a fully defossilized energy system, which can be referred to as the 'Power-to-X economy' or 'Solar-to-X economy' in the case of Chile.

Summary: There is growing interest in transitioning to a carbon-neutral power system that depends on renewable energy sources, driven by concerns about greenhouse gas emissions, energy shortages, and global warming. However, the integration of renewable energy has introduced increased volatility and uncertainty into power system operations. Sector coupling, which involves connecting different energy domains to integrate production, consumption, conversion, and storage, offers a potential solution to meet the needs of each energy sector and reduce surplus energy generation and unnecessary carbon emissions. Despite difficulties in large-scale integration, low conversion efficiency, and economic feasibility, sector coupling presents opportunities to enhance the acceptance of renewable energy and achieve carbon neutrality in traditional power systems. This perspective paper explores the background, definition, components, functions, examples, limitations, and future prospects of sector coupling in rendering power systems carbon-neutral.
