Application of bang-bang control for frequency control in grids with high number of power electronics devices

Abstract

Frequency control is one of the key aspects connected with usage of power electronic devices. On the one hand, replacement of synchronous generation with power electronic interfaces removes kinetic energy of rotor’s rotating mass, making system dynamics more volatile. On the other hand, fast response to control signals calls for a shift control paradigm. In this work a bang-bang primary frequency control is proposed. Its effectiveness is supported by both theoretical results and detailed numerical experiments.
