Optimal Power Flow for a Multi-Energy Vector MicroGrid

Abstract The paper introduces a combined modeling that can allow the Optimal Power Flow of a Multi-Energy Vector merging electric and thermal networks. This topic is motivated by the goal of introducing larger shares of renewable energy in the overall energy consumption, which is hindered by the intermittent nature of these renewable energies. To tackle this problem, it is acknowledged that almost half energy consumption in urban environments is used for thermic objectives. For this reason, a possible solution is to use in parallel electric and thermic networks, called the Multi-Energy Vector. It is then first proposed a combined model, and then aiming at cost optimization, it is performed an optimal power flow, such as to supply references for lower-level controllers, attaining the desired objectives, and keeping all variables inside their operational margins. The proposed scheme is applied to both electric and thermal networks of the under-construction Moulon quarter of Paris-Saclay University. The simulation results illustrate the economic gains that can be made with this joint operation.
