Operational Experiences with a Temperature-Variable District Heating Network for a Rural Community

Melanie Werner et al.

Summary: This study investigates the potential of using temperature-variable district heating systems in rural areas. The study briefly describes a local district heating system in Germany and the NATAR project, and evaluates measurement data. It discusses the advantages of seasonal temperature reduction for different heat generation systems and heat storages. The analysis of measurement data reveals a high optimization potential for solar thermal systems when integrated into both low- and high-temperature storages. Moreover, a combined heat-and-power plant in combination with a CO2 heat pump offers sector-coupling potential and high electricity self-consumption.

Opportunities for installed combined heat and power (CHP) to increase grid flexibility in the US

Hyeunguk Ahn et al.

Summary: This study found that over 40% of the installed CHP capacity in the US in 2019 was not fully utilized, potentially saving up to $16 billion in installation costs and covering up to 9% of ISO/RTO's peak electric demand. Recommendations to enhance grid flexibility include flexible contracts, market design improvements, and simplified interconnection standards.

Load response of biogas CHP systems in a power grid

Shiho Ishikawa et al.

Summary: This study investigates the potential of biogas CHP systems as new resources for supply-demand adjustments in power grids, and finds that they have the potential to contribute to long-term power equivalent adjustment in Germany. However, these systems require several minutes between starting and stopping, and increased emissions are observed during startup.
