Webinar: Study Committees B4 and C4 The GPT without reactive power offers optimal power system efficiency!

The GPT without reactive power offers optimal power system efficiency!

Scope: The General Power Theory (GPT) challenges fundamental aspects of power engineering and existing power theories. Based on a two-part paper in recent editions of Cigre Science and Engineering, and papers and discussion contributions at the Cigre Paris Session 2024, this webinar offers a summary of the GPT’s development, testing, and applications. The experimental test results of implementing GPT control in three different power electronic converters demonstrate that optimal system performance can be achieved without a concept of reactive power. The GPT has significant implications for the electrical power industry worldwide in aspects as broad as converter control, grid codes, tariffs, and understanding and mitigating the effects of geomagnetically induced currents.

Presenters:  Trevor Gaunt, B.Sc.Eng. (Natal), M.B.L. (South Africa), Ph.D. (Cape Town), FSAIEE, is an Emeritus Professor in the Department of Electrical Engineering, University of Cape Town. He was Principal Investigator on research funded by the Open Philanthropy Project on the mitigation of effects of geomagnetically induced currents in power systems, and on UCT’s Advanced GPT Inverter Demonstration project.  He is a Cigre member.

Pitambar Jankee, B.Sc.Eng. M.Sc.Eng., Ph.D. (Cape Town), MIEEE.  His thesis focussed on the implementation of GPT control of power electronic converters and the testing using Hardware-In-the-Loop and in real labs. He has worked with Solution Station in Cape Town and at Ario MeTapower in Pretoria. In April 2024, he joined the Battery Energy Storage Department of Siemens Energy in Erlangen, Germany. His research interests include power-electronic converter control, Battery Energy Storage System (BESS) applications, power theory, geomagnetically induced currents (GICs) and power systems stability. He is a Cigre NGN member.
