Title: Enabling Converter Resource Control in Power Systems with High Renewable Penetration
Abstract: This talk will discuss the need for additional converter control when power systems are operating with high (over 50%) converter-based renewable generation. Traditional synchronous generator controls are set to handle transient, voltage, damping, and frequency stability issues arising from contingencies. With the anticipated retirement of many steam units and replacement by increased proportion of renewable resources, the total system inertia and synchronizing torque will be decreased, affecting power system stability properties and increasing the likelihood of cascading blackouts.
The focus of this talk is to discuss approaches to enable more responsive control of renewable resources to not only recover, but also improve the system stability properties such that system reliability can be maintained under high renewable penetration. One of the added benefits is that with improved control of renewable resources, additional power transfer may be achieved without building new transmission system infrastructure. In addition, electromechanical wave propagation in systems with converters will be discussed, together with control designs that can slow down the propagation speed.
