Protection des données à caractère personnel pour les services énergétiques

Abstract : Smart grids are important bricks in the fight against climate change. Smart grids allow the massive introduction of renewable energies, which are intermittent, while guaranteeing grid stability, i.e., ensuring a real-time balance between demand and production in the power grid. The management of grid stability is possible thanks to smart meters installed in households, allowing the distribution system operator to collect consumption/production data from consumers/producers at a time step of up to 10 min in France. This real-time consumption data enables to provide new energy services, such as customer consumption forecasts or demand response. Demand response services help to avoid consumption peaks in a neighborhood by ensuring that, at all times, users' consumption does not exceed the maximum power of the local grid. However, the collection of users' consumptions is a key privacy concern. Indeed, individual consumption data reflect the use of all electric appliances by inhabitants in a household over time, and enable to deduce the behaviors, activities, age or preferences of the inhabitants. This thesis aims to propose new energy services, while protecting the privacy of consumers. We propose five contributions that relate to two themes:1- The transformation of a demand response algorithm by making it privacy friendly. This transformation uses secure multiparty computation, allowing to compute an aggregate, such as a sum of users’ consumption, without disclosing any individual consumption.2- The publication of sum of users' consumption while preserving privacy and good utility. This publication uses differential privacy, ensuring that the publication of the sum does not indirectly reveal individual users' consumption. Among other energy services, these sums of consumption enable to perform consumption forecasts.
