e2flex
ENABLING FLEXIBILITY
In the e2flex project we will investigate how customers’ preferences will influence the profiles of flexible consumers and if this poses challenges in the distribution grid, due to synchronization. We will develop flexibility products which DSOs can use to resolve congestion and investigate what the value of flexibility is.
The Danish government has set ambitious goals to decarbonize Denmark. One requirement for reaching this goal is the electrification of the transport sector. The number of EVs and plug-in hybrids is increasing rapidly in Denmark. At the same time, electricity prices have increased dramatically within the last year, resulting in customers paying more attention to their electricity consumption and costs. The development of digital solutions enables customers to follow their consumption and correlate it with e.g., electricity prices, CO2-emissions from electricity generation.
