Description
Active control of electricity demand is a key technology when creating a more dynamic, wind power friendly energy system. This demonstration project is about using electricity demand as fast reserves. This is an alternative to some of the most expensive reserves in the current electricity system.
Conceptually, both generation and demand can be used for frequency control in power operation, though only the former is primarily used today irrespective of the high costs and sometimes slow response. In contrast, many electricity demands such as electric heating, refrigerating and freezing have advantages as frequency reserve including low costs, pollution free, fast and flexible response with little impacts to customer or appliances. This project focuses on investigating the appropriate use of demands as frequency reserve (DFR) with strong focus on hardware development and demonstration in a practical power system based on our previous research. The project will have as objectives to:
-
Practical hardware development of the technology for frequency controlled demand (DFR)
-
Validate and evaluate the technology's field performance of reserve provision
-
Evaluate the technology’s actual impacts on appliance operation through large-scale demonstration of hundreds of such devices.
-
Test and further develop monitoring methods for DFR appliances concerning the needs of the transmission system operator (TSO)
-
Obtain first-hand experience and feedbacks, and evaluate customer's acceptance of the technology.
-
Further develop DFR control logics to fulfil specific rules of UCTE and Nordel
