ETEM-SG: Optimizing Regional Smart Energy System with Power Distribution Constraints and Options

Résumé

This paper gives a detailed description of the ETEM-SG model, which pro- vides a simulation of the long term development of a multi-energy regional energy system in a smart city environment. The originality of the modeling comes from a representation of the power distribution constraints associated with intermittent and volatile renewable energy sources connected at the transmission network like, e.g. wind farms, or the distribution networks like, e.g. roof top PV panels). The model takes into account the options to optimize the power system provided by grid friendly flexible loads and distributed energy resources, including variable speed drive powered CHP micro-generators, heat pumps, and electric vehicles. One deals with uncertainties in some parameters, by implementing robust optimization techniques. A case study, based on the modeling of the energy system of the “Arc L ́emanique” region shows on simulation results, the importance of introducing a representation of power distribution constraints and options in a regional energy model.

Variable renewable energy
Variable renewable energy (VRE) or intermittent renewable energy sources (IRES) are renewable energy sources that are not dispatchable due to their fluctuating nature, such as wind power and solar power, as opposed to controllable renewable energy sources, such as dammed hydroelectricity or biomass, or relatively constant sources, such as geothermal power. The use of small amounts of intermittent power has little effect on grid operations. Using larger amounts of intermittent power may require upgrades or even a redesign of the grid infrastructure.
Photovoltaic system
A photovoltaic system, also PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and other electrical accessories to set up a working system. It may also use a solar tracking system to improve the system's overall performance and include an integrated battery.
Réseau de distribution électrique
Un réseau de distribution électrique est la partie d'un réseau électrique desservant les consommateurs. Un réseau de distribution achemine l'énergie électrique d'un réseau de transport (Haute tension B) ou un réseau de répartition (Haute tension A) aux transformateurs aériens desservant les clients. La tension électrique des réseaux de distribution se situe normalement entre . Ils comprennent des postes électriques de transformation, des lignes aériennes et un réseau de conducteurs les reliant aux transformateurs de secteur.

Optimal DSO grid control for energy communities with high PV penetration and electrochemical storage

Photovoltaic generation is a non-controllable energy source, hence a high share of distributed PV installations in low-voltage networks may lead to over-voltage and lines or transformer overloading. To avoid these, the Distribution System Operator can curt ...
