„Inertial energy storage device for local electrical microgrids protection”

Due to industrial development correlated with population growth, the demand for energy continues to grow. The context of the global dynamics in terms of climate change has determined that Romania also undertakes through PNIESC to reduce greenhouse gas emissions by 43.9% by 2030 compared to 2005 values ​​and to increase the global share of energy from renewable sources in gross final consumption by 30.7%.

Inertial energy storage systems based on the flywheel principle, known in the literature as “Flywheel Energy Storage System” (FESS), are gaining more and more attention from the scientific community due to the fact that they can be a viable solution to the problem related to the intermittent nature of energy from renewable energy sources. In addition, the level of technological development achieved by additive manufacturing as well as the new composite materials on the market, which have a remarkable potential in terms of the energy density that can be stored and subsequently returned by the flywheel, all of these redefine the concept of FESS, companies important at the international level investing in the research and development of these systems.

The objective of the project is the development of a prototype of an inertial device for energy storage and electromagnetic protection of the local electrical network and the validation in relevant operating conditions of this device with additional protection capabilities, which will be able to develop a power of P = 2kW, the discharge time being at least td = 10 min. The innovative character is related to the realization of an inertial device which, in addition to the energy storage function, ensures permanent protection against voltage peaks and against parasitic electrical elements. The new product, intended for subsequent introduction into manufacturing at the project coordinator ICPE SA whose object of activity is technological research and development, is addressed to banks, medical units, the information storage sector, etc., will be designed for powering IT equipment, for example in special laboratories, units of strategic interest, therefore aiming at the protection and rapid storage of data. As a result of the project, positive technological effects (development of an innovative technology for efficient and non-polluting energy storage) and significant economic effects are estimated, ICPE SA thus being able to expand its research capacity, at the same time diversifying its range of products adapted to the new requirements of performance and efficiency, thus assimilating the results of research and development carried out by project partners ICPE-CA and UTCN.

DISEP is a project financed by UEFISCDI through the P2 program – Increasing the competitiveness of the Romanian economy through CDI, “Transfer to economic operator” subprogramme. The project runs from June 21, 2022 to June 20, 2024 (24 months).
