During all the duration of the GreenerNet project, most of the partners have been involved along an active cooperation in order to identify and realize the top-end level design related with the entire GreenerNet system.
All the activities have been organized, focused and centered on the developing of the total energy system, ranging from the MEA (Membrane Electrodes Assembly) up to BMS and BCS (Battery Managment & Control System).
The 4 levels controlling architecture, by means BCS and BMS together with the Microgrid Managment system (MMS) and the Energy Managment System (EMS) have been totally developed with the main objective to integrate them within a microgrid controlling energy system.
Following the above frameworks and technology scenarios, partners like ENG, EVOPRO and GES strongly cooperated together on the best definition of the technology’s application, in particular, the definition was focused on the application windows where the technology can really be applied.
All the main GreenerNet activities then, have been centralized on the definition of detailed case studies, tests and activities planning for all the process and evaluation of all the possible end-user scenarios.
A number of high performance RFB (Redox Flow Battery) for a stand-alone and grid-based energy systems solutions and applications have been successfully manufactured and installed over a planned pilot site in Budapest.
During all the mentioned field tests and activities, preliminary data collection and analysis have been performed and investigated in order to improve the system for the next RFB generation and for all the system in large.
Pilot site studies, covered all the specific behaviour of all the entire systems as such as the change-over between “grid-on/grid-off” switch performance and energy flow optimization.
A series of standalone deep charging/discharging processes have been performed as well, all the data collected and the next data analysis proved the coherence between field test and theoretical results.
The in-field tests had the main objective to validate the following principal aspects:
– the microgrid in large;
– a power-to-power battery system setting and,
at the same time
– validate all the single BCS and the BMS developed systems in order to control and monitor all the main energy related physical variables.
GreenerNet’s objectives and targets, during the in-field tests have been achieved in both stand-alone and microgrid configurations. Each test has been addressed and focused on real applications for each energy storage system.
During all the pilot tests, charging-discharging procedures, communications between BCS/BMS and the entire micro grid cluster have been successfully executed and targets achieved.
Batteries security analysis and tests have been performed as well, driving all the accumulation systems above the limit of their standard performance in order to investigate all the security controls and mitigations and then map all the security performance.
