SS3: Control of Microgrids and Power Systems with High Penetration of Converter Interfaced Resources


While ever-decreasing costs of power electric devices make large-scale deployments of renewable generation very appealing, its impact on the reliability and resilience of the electric power system is highly problematic. Today’s grid operation heavily relies on bulk generation and synchronous machines that provide significant amounts of rotational inertia, maintain self-synchronization through the power network, and ensure stable and reliable operation of the power system through their frequency and voltage control. The loss of rotational machine inertia has received significant attention recently, while it is just one of a multitude of stability challenges that arise. How to operate the converter-dominated power system with high share of renewable needs further study. In this context, this panel will focus on the new theoretical insights, innovative modeling technique and control methods on the operation of microgrids and power systems dominated by power electronics. This session will explore several topics that are becoming increasingly prevalent, but not limited to the following:

  1. Simulation results and impact analysis of high penetration of renewables integration on power system reliability and operation.
  2. Design and application of new control techniques for power converter in renewable electric system.
  3. Innovative control and operation methods for high-renewable power systems.
  4. Strategic control of flexibility resources, including energy storage, demand response for enhancing the reliability of high-renewable power systems.
