• The prosumers f lexibility procurement has increased due to the current penetration of distributed and variable renewable energy sources. The prosumers f lexibility is often able to quickly adjust the power consumption, making it well suited as a primary and secondary reserve for ancillary services. In the era of smart grids, the role of the aggregator has been increasingly exploited and considered as a player that can facilitate small prosumers’ participation in electricity markets. This paper proposes an approach based on the use of prosumers f lexibility by an aggregator to support ancillary services at a low voltage level. An asymmetric pool market approach is considered for f lexibility negotiation between prosumers and the local marker operator (aggregator). From the achieved results it is possible to conclude that the use of f lexibility can bring technical and economic benefits for network operators
