Of particular interest to grid-tied operation are those controllers that can mimic the inertial behavior of the conventional synchronous machines since the decrease of inertia will pose a serious issue in future power grids. These controllers are called VSM - Virtual Synchronous Machines, a family the synchronverter control concept is part of. In this paper we strive for augmenting the foundations of the synchronverter control and parameter tuning method already laid down in [1] by introducing the filter capacitor and the resistances into the small-signal model. Using parameters determined based on small-signal stability calculations we show how the synchronverter is capable of islanded and grid-connected operation, synchronizing to the grid via a synchronizing impedance. The controller is tested on a power hardware-in-the-loop (PHIL) simulator with an emulated external grid capable of giving frequency response. Simulation results indicate that the transfer from islanded to grid-connected operation of the synchronverter is seamless after a fast synchronization, while the controller can help in the frequency containment process (FCP).}, keywords = {island operation; Synchronverter; inverter control; swing equation; Grid-connected operation}, year = {2022} } @inproceedings{MTMT:33282181, title = {Comparison and specification-based tuning of two grid-forming inverter controllers providing inertia}, url = {https://m2.mtmt.hu/api/publication/33282181}, author = {Sütő, Bence and Divényi, Dániel and Raisz, Dávid}, booktitle = {2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)}, doi = {10.1109/PEDG54999.2022.9923191}, unique-id = {33282181}, abstract = {As the proportion of renewable energy generation grows worldwide, there is an increasing demand for electronic solutions that support power system stability. Grid-forming (GFM) inverters that provide virtual inertia will likely be one of the key elements in future power systems. However, no clear guidelines or specifications do yet exist for the selection of the controller structure and its parameter tuning. There are several GFM approaches published in the literature, from which two virtual synchronous machine (VSM) structures are compared in this paper to identify which controller is more convenient from the point of view of specification-based parameter-tuning. First, the dynamics of the active and reactive power loops are expressed via a theoretic, small-signal analysis-based approach. Using the derived models, the converter parameters are tuned to provide identical behavior to power reference changes. The comparison and the evaluation of the theoretic models are carried out using offline simulations and PHIL demonstrations. Results indicate that the VSM cascade model corresponds to its theoretical model, while the synchronverter is more prone to dealing with stability issues in hardware implementation.}, keywords = {converter control; Synchronverter; Grid-forming converter; power hardware-in-the-loopsimulation}, year = {2022} } @inproceedings{MTMT:33067588, title = {Feasibility study of a local peer-to-peer energy market: Implications on a real-life LV distribution grid}, url = {https://m2.mtmt.hu/api/publication/33067588}, author = {Sütő, Bence and Sinkovics, Bálint and Táczi, István and Barancsuk, Lilla and Polgári, Beáta and Sőrés, Péter Márk and Hartmann, Bálint and Divényi, Dániel and Vokony, István and Csercsik, Dávid}, booktitle = {2022 8th International Youth Conference on Energy (IYCE)}, doi = {10.1109/IYCE54153.2022.9857520}, unique-id = {33067588}, abstract = {The H2020 INTERRFACE project designs, develops, and exploits an Interoperable pan-European Grid Services Architecture to act as the interface between the power system (TSO and DSO) and the customers and allow the seamless and coordinated operation of all stakeholders to use and procure common services.

In this paper, a network modeling method is introduced and validated through the metering data of a test area. The model considers voltage limits, asymmetry, and overloading violations. Simulation results show that the modeling considerations are adequate to analyze the effects on the local grid assets and provide reflective tariff signals for proper grid utilization.
