Demand side management certification and control on the distribution network

A shift toward renewable energy and consumption management recently began in the power system. The Distribution System Operator (DSO) has to face an increasing number of grid connected actors (electric vehicles supply equipment's owner, pool aggregator, local generation, etc.) and still ensure grid security with the emergence of these new uses. One of these new uses is demand response (DR). DR is activated by a new actor called pool aggregator. The DR process is divided in three steps: Ex-Ante (before DR activation), DR Activation, and Ex-Post (after DR activation). After some development on the transmission network, DR is now appearing on the distribution network. The aim for DSOs in smart grid projects is to ease the development of DR and to become a neutral market enabler and trusted third party for the markets. The underlying principle is to guarantee fair access condition to all grid connected actors and maintaining power quality on the network. This paper presents some developments made by ERDF in Ex-Ante and Ex-Post within the context of French smart grids projects in order to integrate the DSO in the DR process.
