Complexity in Grid-Connected Power Electronics and its Impact on Power Grid Development
C. K. Michael Tse
Abstract
A variety of active loads and power conversion systems are connected to the power grid to support various emerging and essential applications. The types of loads and power conversion interfaces are becoming diverse, including EV chargers, power supplies for datacenters, interface systems for renewable sources and storages, grid-forming systems, etc. These systems interact with the grid and with each other, posing stability challenges to the power delivery system due to the complex dynamics of grid-connected power electronics systems as well as the weakening of the inertia necessary for maintaining frequency and voltage control. In this talk, we will present the key set of phenomena arising from the complex dynamics of power converters. We will focus on the two main categories of converters, namely, grid-following and grid-forming converters, and discuss the implications of their inevitable inclusion in the power grid as we strive to escalate the development of cleaner power supply systems.
