RECKON Project at the EPE 2026 International Conference: The Future of Export Control in Local Grids

Representatives of the RECKON project attended the EPE 2026 international conference in Opole, Poland, where they presented research results in the field of energy balance modelling. The work focuses on advanced export control in prosumer sites.

The paper titled "Pre-deployment Energy Balance Modeling and PV Yield Estimation for Export Control in Prosumer Sites: The RECKON Workflow" was jointly presented by Jakub Jiřinec (TBE electric s.r.o.) and Vojtěch Vurm (University of West Bohemia in Pilsen). The presentation focused on an innovative workflow that enables effective limitation of active power exported to the distribution grid — a key concern particularly in the context of Czech legislation and penalties for exceeding agreed limits at the point of common coupling. Based on one year of minute-resolution data from one industrial and three residential sites, the authors developed energy models in the MATLAB/Simulink environment, supplemented by long-term PV yield estimates from the PVGIS system. The main contribution is an analysis of export control potential and a simulation of two strategies (step-based and dynamic), which in the test scenario significantly reduced peak power injections into the grid.

The presented results from pilot sites in the Czech Republic, as well as yield comparisons with locations such as Istanbul and Budapest, attracted well-deserved interest at the conference.
