The execution pf RESOLVD has been split in 9 work packages: WP1(use case and requirement analysis), WP2 (power electronics technologies), WP3 (observability: components and technologies), WP4 (integration and data platform), WP5 (integration and validation -not started-), WP6 (business models and exploitation), WP7(dissemination and communication), WP8 (management) and WP9 (ethics). During the first 18 months the efforts focused on the consolidation of the overall project specifications and starting the development of individual components accordingly. Second term extended until month 42, and continued with the individual validation of software and hardware components and their further integration in the RESOLVD platform, deployment in the pilot site and validation in the real environment.
Thus, WP2 has focused on the construction and validation in the laboratory of the power electronics device, its integration with heterogeneous groups of batteries and the development of power sharing algorithms to optimally manage them. WP3 included activities to improve grid observability and management strategies: test and validation of algorithms for energy (demand and generation) forecasting, fault detection and isolation and grid operation scheduling and the implementation of the corresponding APIs, ready for integration. Also in WP3, three hardware developments were completed: synchrophasors –PMUs-, power quality monitors –PQMs- and associated gateways -GW-. Integration off these HW and SW components and modules previously described, together with legacy system in a single platform under the Enterprise Service Bus (ESB) paradigm and managing the corresponding data flows was the focus of WP4. Piloting, test and validation was the focus of WP5. It started with the definition of test scenarios and selection of KIPis accordingly; followed by conditioning the pilot site and finally deploy and execute the validation tests accordingly.
The tests performed in the pilot demonstrated the capability of RESOLVD solutions to improve the voltage profile in LV grids in 1.7% by injecting power to correct voltage variations due to variations on generation and demand. Also the use of batteries in the pilot allowed a reduction of 9% of transport losses due to a reduction of exchanged energy at substation level together with a peak reduction of 18-19% in the daily demand profile. Versatility of the power electronic device was demonstrated in the improvement of power quality (phase compensation, harmonic reduction) resulting also a reduction of transport losses estimated in 166.7W/Ohm.
Apart from research and technical activities, the developments have been accompanied of a very intense work in WP6 that result in a set of individual Key Exploitable Results derived from technological developments (Power Electronics Device managing heterogeneous batteries, Phasor Measurement Unit (PMU) & Edge Computing, Power Quality Monitor And Smart Gateway, Enterprise Service Bus (ESB) and Data Management Platform, Cybersecurity Methodology, RESOLVD LV Decision Support Toolkit (LVD-DST)) that can be combined in several packages to satisfy multiple DSO necessities. For them, associated business models and exploitation plans have been developed.
Results from all these activities have been reported in multiple communication and dissemination actions within WP7 with a great involvement and commitment of all the partners, resulting in 18 conference papers and 6 journal papers (plus other 7 under review/preparation) and many networking, demo and survey activities.
