R&D NESTER DEVELOPS CONTROL MODEL FOR FLEXIBLE SYNCHRONOUS GENERATION WITH EUROPEAN PARTNERS
Within the scope of the activities of the European Project FLEXITRANSTORE ("An Integrated Platform for Increased FLEXIbility in smart TRANSmission grids with STORage Entities and large penetration of Renewable Energy Sources") and the demonstrator associated with activity 12.3 (Implementation and demonstration in a hybrid environment), the report associated with this task was successfully delivered to the European Commission at the beginning of May.
This report addresses a key phase of the WP12 (Work Package), which encompasses the activities of demonstrator 8 - "Advanced Control for flexible synchronous generation", where the developed system was tested in a real-time simulation environment. This WP addresses the demonstration of innovative models of control and tuning of the Power System Stabilizer (PSS) of generators in order to improve the damping capacity of low frequency oscillations (LFOs), strengthening the network as it increases generation flexibility.
In this work, R&D NESTER contributed to the development and implementation of a model based on the physics of the phenomenon (Grey Box Model) to predict the behavior of the electrical network in various operating scenarios, focusing on the events that originate this type of low frequency phenomena (LFOs).
The model developed by R&D NESTER is part of an integrated system, target of demonstration, which allows to adjust the parameters of the PSS in real time, optimizing the response of the generation, thus increasing the resilience and flexibility of the electrical system. The demonstration in real environment of this system is planned to start in the next months in a cogeneration plant in Bulgaria.
This project, in which R&D NESTER participates, is financed through Grant Agreement N. 774407 of the European Research and Innovation Program H2020.
