POwering SYstem flexibiliTY in the Future through RES (POSYTYF)


Topic: Development of solutions based on renewable sources that provide flexibility to the energy system (LC-SC3-RES-16-2019).Increasing the part of Renewable Energy Sources (RES) in modern power grids is critical for transforming the global energy system. However, stability and participation in ancillary services issues related to RES limit their use. Indeed, the RES grid integration faces major limitations when high renewable energy (RE) penetration is expected. A solution to overcome this is to increase the share of so-called dispatchable RES, i.e., those with a natural storage capacity. The main objective of the POSYTYF project is to group several RES into a systemic object called Dynamic Virtual Power Plant (DVPP). DVPP is a way to aggregate RES sources to form a portfolio of dispatchable/non-dispatchable RES able to optimally internally dispatch resources in case of meteorological and system variations to provide sufficient flexibility, reliable power output, and grid services.

The POSYTYF project will provide TSOs (transmission system operators), DSOs (distribution system operators), and generators with knowledge, mathematical models, and design tools for the synthesis of DVPP control both for local (production) and grid (ancillary services) objectives. The new analysis (stability assessment) 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 in simulation and hardware in the loop along with the codes for the 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 ten partners from 4 EU countries. They will bring the VPP technology from TRL 3-4 to TRL 4-5 by evaluating new stability issues and proposing new control algorithms.
