Loadability Limits Under Periodic Load Forcing
Maitraya Avadhut Desai, Gustavo Valverde, Gabriela Hug
The static loadability limit, defined as the demand at which the equilibrium equations lose their solution, is the standard basis for interconnection screening of large new loads.…
Dynamic Optimization of Virtual Inertia and Damping in Converter-Based Power Systems
Jovan Krajacic, Maitraya Avadhut Desai, Ognjen Stanojev +1
The transition towards a sustainable power system is enabled by the replacement of conventional synchronous generators with converter-interfaced renewable energy sources. However,…
Next-Generation Grid Codes: Towards a New Paradigm for Dynamic Ancillary Services
Verena Häberle, Kehao Zhuang, Xiuqiang He +3
This paper introduces a conceptual foundation for Next Generation Grid Codes (NGGCs) based on stability and performance certificates, enabling the provision of dynamic ancillary se…
Network-Independent Incremental Passivity Conditions for Grid-Forming Inverter Control
Jared Miller, Maitraya Avadhut Desai, Xiuqiang He +2
Grid-forming inverters control the power transfer between the AC and DC sides of an electrical grid while maintaining the frequency and voltage of the AC side. This paper focuses o…
