Abstrakt

Increasing penetration levels of intermitttent renewables are posing challenges to system operators and electricity producers. In West Denmark, which is a paradigmatic case by global comparison in terms of combining intermittent renewables and distributed cogeneration, we find that distributed cogeneration plants rather than central power plants are giving way for wind power in the electricity mix. Could intermittent renewables be a threat to the system-wide energy, economic and environmental benefits that distributed cogeneration have to offer?
This paper investigates how existing cogeneration plants may adapt their plant design and operational strategy to improve the co-existence between cogeneration and intermittent renewables.
A novel intermittency-friendly and super-efficient concept in cogeneration is presented that involves integrating a high-pressure compression heat pump using heat recovered from flue gasses as the only low-temperature heat source, furthermore applying an intermediate cold storage allowing for non-concurrent operation of heat pump and cogeneration unit.
The novel concept is subject to a detailed techno-economic comparative modelling and analysis, hich finds the concept to be the most cost-effective option for increasing intermittency-friendliness.
