PUMPED THERMAL ELECTRICITY STORAGE INTEGRATION IN DISTRICT HEATING SYSTEMS
The elspot price sharp variation in electrical grid should be considered as opportunity for district heating network sources. Renewable cogeneration power plant can integrate thermal energy storage by implementation of two elements: heat pumps and secondary thermal engine like Organic Rankin Cycle turbine. The analysis of statistic data for elspot price and heat consumption for heating clearly reveals free room for application of electrical energy export/import for improvement of total biomass energy source. The concept of Levelized Cost of Storage together with estimation of round-trip-efficiency are used to evaluate relation between main storage parameter: size and lifetime of system to get best possible combination of operating parameters.
