Abstract : Increasing needs in energy, and earth pollution, coming from the use of polluting and non-renewable energy, make it indispensable the design of new energetic models, sustainable and reliable. Today, these new models are based on a massive integration of renewable generators in the grid. The renewable integration issues come from their stochastic features, depending on the weather conditions, most of the time. The coming of new information and communication technologies allows the integration of an information layer to the energy grid allowing it to be smarter and allow to have a glimpse of the possibility of a decentralised management of renewable energy. These energy being mainly decentralised, unlike imposing nuclear, coal and gas power plants, are produced directly at the customer's location. Consumers become, then, a prosumer able to answer to its own energetic needs,and maybe to act as a producer if it produces more energy than it consumes. But, the coming of a plethora of small actors, able to buy and sell energy, in real time, in a market containing the more powerful actors, traditional in the market, can be a source of volatility for energy prices. Considerable variations of the price can lead to detrimental situations by disturbing the grid. To face this problem, we developed a first mechanism for automatic negotiations, on three time scales, which decrees constraints on demand and on prices in order to guarantee their stability. This mechanism rely on representative entities (producers, prosumers and aggregators) to manage demand and supply without taking into account the impact on the grid of the negotiated contracts between these entities. The second mechanism, based on blockchain technology, allows bilateral decentralised negotiations and take into account the physical impacts on the grid of each energy exchange between prosumers, guaranteing then, the grid integrity. The proposed mechanism exempt itself from a management of the grid stability from a centralised third part
