Day-ahead Trading of Aggregated Energy Flexibility

Abstract

Flexibility of small loads, in particular from Electric Vehicles (EVs), has recently attracted a lot of interest due to their possibility of participating in the energy market and the new commercial potentials. Different from existing work, the aggregation technique proposed in this paper produces flexible aggregated loads from EVs taking into account technical market requirements. The flexible aggregated loads can be further traded in the day-ahead market by a Balance Responsible Party (BRP) via the so-called flexible orders. As a result, the BRP can achieve more than 19% cost reduction in energy purchase based on the 2017 real electricity prices from Danish electricity market.
