Evaluation of residential up and down-regulation participation for additional flexibility of distribution grid: French case

This article deals with the world energy transition process and in particular with the European target to reach the distributions grids additional flexibility. It introduces notions of flexibility, its advantages and the actual crucial utility for the distribution grid, also as new sources of flexibility thought demand side ancillary services. Due to the distributed renewable energy deployment, smaller and smaller consumers become prosumers and can also provide additional electricity or ancillary services to the distribution grid among conventional and centralized sources. Actual research studied application of previously presented the up and down-regulation flexibility ancillary services algorithm for the prosumer’s battery energy storage system participation. The practical evaluation applied this algorithm on the real prosumers case, situated in the Paris region, France, with the aim to evaluate the attractiveness, feasibility and practicability of ancillary services participation in the current French legislation frameworks. The technical and economic analysis of the real data evaluation presents from one side the economical attractiveness of this service participation for the considered real prosumer without degradation of its battery storage lifetime. From another side, it allows the distribution grid to achieve much needed additional flexibility.
