Grid Interactive Power Converter Controls and their Fault Ride-Through Capability Presented by Iqbal Husain and MA Arwal
Abstract: In the recent decade, we have seen an unprecedented growth of renewable generation and we are experiencing a changeover from the traditional model of centralized generation to a mix of centralized and distributed generation in the power grid. Integration of local generation, load and/or storage molds is currently finding widespread applications in large scale data centers, renewable energy integrations, electric ships, and commercial/industrial buildings bringing the benefits of high efficiency, power quality, flexibility, stability, and reliability. There is also the recent increase in the adoption of electric vehicles, consumer electronics, and computing. Power electronics is the key technology that connects modern customers with utility by enabling distributed generation, microgrids as well as the integration of this new class of loads. The interfacing power electronics converters are embedded with advanced controls, and are often capable of collaborative operation in a networked scenario.
Significant advances have been made in recent years by both academia and industry to achieve low and medium voltage interconnection between utility and customers through wide bandgap power devices, innovative converter topologies, and soft switching techniques. Robust controllability, flexibility of operation, reliability and lower operating cost have been the major driving factor behind the adoption of these power electronics enabled technologies. To achieve such level of robustness and reliability in microgrids and in networked power electronics systems, controls play a key role where they are implemented in a hierarchical manner starting from local power converter controls to primary to secondary and to tertiary levels. The primary controls are responsible for power sharing among multiple sources and stability of the system, while secondary and tertiary controls are for retaining nominal operation through energy management and economic optimization. The control challenges are immense both due to interaction among the power electronics converters and the intermittency of the renewables. As the power electronic converters are actively controlled units, they introduce highly nonlinear and time varying dynamics and the interaction among different units may lead to instability in interconnected systems. Much of the existing autonomous and distributed control in power systems relies on temporal and spatial decoupling among the phenomena being controlled. A system with multiple power electronics converters is bound to be affected by the faster switching surge dynamics to slower frequency control both qualitatively (novel dynamics) and quantitatively (many more components). In that aspect, despite substantial efforts put forth by both academia and the industry, fault ride-through (FRT) of inverter based resources (IBRs), particularly for grid forming (GFM) controls, remains an open research question. The underlying synchronization mechanism employed during fault and the real and reactive power output as a consequence, plays a vital role in the stability of the associated grid, especially after fault clearing.
This tutorial on grid interactive inverters is designed to cover the components, system architectures and controls, ancillary services and grid support, and customer interactions and benefits in the context of microgrids and networked power electronics based systems. This tutorial is organized into four parts: Part I provides a review of basic components of microgrid and distributed generation in a modern power system; Part II presents motivation, system architecture, and control objectives for residential and commercial systems; Part III covers the two dominant strategies, namely, grid-following (GFL) and grid-forming (GFM) control, for IBRs; Part IV highlights the need for in-the-loop modelling and simulation for both IBR development and interconnection studies; and Part V presents the challenges and recent advances on fault ride-through (FRT) control solutions for IBRs to augment grid support under various transients. Finally we will conclude with some thoughts on trends into the future for widespread industrial adoption.
