Description du projet
Des sources d’énergie renouvelable acheminables pour un modèle de réseau électrique moderne
La pénétration croissante des énergies solaire photovoltaïque et éolienne requiert des réseaux électriques modernes capables de transporter l’électricité de manière fiable, des producteurs vers les consommateurs. L’intégration de plus en plus poussée des sources d’énergie renouvelable (SER) se heurte toutefois à certaines limites. Une solution consiste à augmenter la part des SER dites acheminables (celles qui sont dotées d’une capacité de stockage naturelle). Le projet POSYTYF, financé par l’UE, regroupera plusieurs SER au sein d’un objet systémique baptisé «centrale électrique virtuelle». Il s’agit d’un moyen de regrouper différentes sources d’énergie renouvelables pour constituer un portefeuille de SER acheminables / non acheminables, permettant de redistribuer les ressources de manière optimale et interne. Le projet rassemblera des partenaires provenant de quatre pays de l’UE.
Objectif
Increasing the part of Renewable Energy Sources (RES) in modern power grids is of critical importance for the transformation of the global energy system.
However, stability and participation to ancillary services issues related to RES limit their use. Indeed, the RES grid integration faces major limitations when high RE penetration is expected. A solution to overcome this is to increase the share of so-called dispatchable RES, i.e. the ones which have a natural storage capacity. The main objective in the POSYTYF project is to group several RES into a systemic object called Virtual Power Plant (VPP). VPP is a way to aggregate RES sources to form a portfolio of dispatchable/non-dispatchable RES able to optimally internally redispatch resources in case of meteorological and system variations in order to provide sufficient flexibility, reliable power output and grid services.
The POSYTYF project will provide TSOs, DSOs and generators with knowledge, models and tools for synthesis of VPP controls both for local (production) and grid (ancillary services) objectives. New analysis (stability assessement) and control (centralized vs decentralized concepts) methods will be particularly proposed. Solutions will be immediately implementable in the actual grid and regulatory situation. Realistic (large-scale grids and concrete RES technologies) cases will be treated and full validations – both in simulation and hardware in the loop along with the codes for regulator’s implementation will be made available. Proposals for some main problems like stability will be formulated for next generation grids of massive RES penetration and low inertia systems.
The interdisciplinary and ambitious POSYTYF project brings together 10 partners from 4 EU countries. They will bring the VPP technology from TRL 3-4 to TRL 4-5 by evaluating new stability issues, proposing new control algorithms.
