Power systems worldwide are going through a paradigm shift. Millions of distributed energy resources (DER) are being connected to power systems, which imposes unprecedented challenges to grid stability, reliability, security, and resiliency. Recent research has shown that it is promising to seamlessly integrate expertise in control systems, power electronics, and power systems to achieve power electronics-enabled operation of power systems to address these issues. This workshop has over 130 participants from funding agencies, regulatory commissions, utilities, think-tanks, vendors, and universities etc. to offer multidisciplinary perspectives on the paradigm shift of power systems and identify the associated challenges and needs, and potential tools and methodologies. Recommendations will be made after the workshop. This will help speed up the paradigm shift of power systems, improve the stability, reliability, security, resiliency of future power systems, promote sustainability, create jobs, and stimulate economic growth.

The fundamental challenge behind this paradigm shift is that future power systems will be power electronics-based, instead of electric machines-based, with a huge number of active, intermittent, non-synchronous, and heterogeneous players. The objective of this NSF workshop is to bring experts from control systems, power electronics, and power systems together to identify fundamental challenges and needs in multidisciplinary research and education in control of power electronics-enabled power systems for enhanced grid stability, autonomy, scalability, operability, reliability, security, and resiliency; strengthen collaborative efforts to tackle the challenges identified; and raise the awareness of funding agencies and policy-makers to support and nurture research and educational activities to advance fundamental knowledge, enabling technologies, and workforce in this area.

Title: Enabling a Power Electronics Grid

Abstract: The requirement for distributed real-time control in the future grid using power converters is being driven by rapid growth in distributed energy resources, microgrids and the need for dynamic real-time balancing between generation and loads. The move from centralized control to massively decentralized and distributed control raises further challenges, both in terms of the converters and feasible control strategies, as well as the architecture and infrastructure required to manage and operate such a system. This presentation will discuss power converter topologies, control strategies and system architecture for managing such a future grid and related loads. Key topics include grid integration strategies for managing a fleet of such devices to deliver value for the future and present grid.

TitlePower Electronics-enabled Autonomous Power Systems: Synchronized and Democratized (SYNDEM) Smart Grids

Abstract: Power systems are going through a paradigm shift. The centralized large facilities are being replaced by millions of widely dispersed non-synchronous relatively small renewable or alternative power plants, plug-in EVs, and energy storage units. Moreover, the majority of loads are expected to actively take part in the grid regulation in the same way as suppliers do. In this lecture, the SYNDEM (meaning synchronized and democratized) grid architecture, together with its technical route, to enable this paradigm shift will be presented. It will be shown that the synchronization mechanism of conventional synchronous machines, which has underpinned the power systems for over 100 years, can continue playing its fundamental role in power systems. It will empower all power electronics-interfaced suppliers and loads to behave like virtual synchronous machines so that they can take part in the regulation of system frequency and voltage, in the same way as conventional synchronous machines do. This will unify the integration and interaction of all players with the grid. It will also release the communication infrastructure from low-level control and open up the prospect of achieving autonomous operation for power systems without relying on communication networks. This holistic solution could considerably enhance the stability, scalability, operability, security, reliability and resiliency of the next-generation smart grid.

Title: Optimizing Ubiquitous Power Electronics for the Future Power Grid

Abstract: Power systems world-wide are evolving towards a new mix of generating resources, transmission networks, and consumption devices. For example, wind and solar generation are rapidly growing in recent years; DC power lines, flexible AC transmission systems, and solid-state transformers are changing the power networks; electric vehicles are increasing their shares as electric loads; and energy storage is being used for all stages of the power system. One thing in common in such evolutions is power electronics. As a result, a high percentage of electricity will be generated, transmitted or consumed by power electronics in the future power grid. Such a high penetration of power electronics will significantly change power system operation landscapes and dynamic characteristics. The reduced system inertia by power electronics-connected generations and consumptions has caused significant concerns in the power system community, while the high-speed control capabilities of power electronics present new opportunities for achieving an optimal performance of the power system. The fundamental challenge is how to get there. Solving this challenge requires several important steps: modeling and simulation to understand the behaviors of power electronics and its interactions with other components in the context of power systems; and control and optimization methods for fully utilizing the capabilities of power electronics for a new paradigm of performance beyond the traditional inertia-based system. This talk will summarize the trend of power electronics development and applications, explore potential solutions, and pose some of the challenging questions for further discussions.

Title: Technical Challenges of High Level of Inverter-based Resources in Power Grids

Abstract: Massive penetration of variable renewable energy (RE) in addition to other distributed energy resources, (DER) poses major operational challenges to utility system operators. Traditionally, power system operation assumes synchronous generators provide frequency stability via their stored kinetic energy. With increasing inverter-based sources the system’s inertia is reduced and frequency stability becomes a concern. This increased penetration represents ground zero for the disruption of the global energy landscape caused by DER.  Our overarching objective is to transform the installation of very large numbers inverter bases sources from a major potential liability into a critical asset for both the power grid and utility customers.

Title: Flexible Division and Unification Control Strategies for Resilience Enhancement in Networked Microgrids

Abstract: Networking a series of autonomous microgrids (MGs) is a strategic effort toward the resilience enhancement in extreme conditions. We consider flexible division and unification control strategies to help networked MGs prepare adequately for extreme events and adapt comprehensively to subsequent changing conditions, which enhance the system resilience. Networked MGs can switch between two distinct modes of division and unification by utilizing a sparse communication network without requiring any additional communication infrastructures or controllers. In division mode, each MG is regulated by its local master controller (MC) for active power sharing, which ensures that disruptions are handled effectively by local energy resources without utilizing those in adjacent MGs. Thus, any islanding or resynchronization of individual MGs would not introduce further disruptions to the remaining networked system. In unification mode, the remaining networked MGs, which are still functional, share all available energy resources and adapt to continuously changing operating conditions in order to respond to extreme events. The proposed control algorithm for devising a flexible networked MG system is a cost-effective scheme that can fully exploit the system operation flexibility corresponding to different operation stages for enhancing the resilience. The proposed control strategies are applied to a networked MG system and the performance is tested using time-domain PSCAD/EMTDC simulations.

Title: Medium Voltage Power Electronics Technology

Abstract: Through the development and commercialization of technology over the last fifty years, power electronics technology for low voltage systems (<480 V) can be easily achieved by using silicon IGBT technology. Newer semiconductor device based on SiC that can handle much higher voltage and higher switching frequency were only becoming available in the last decade. SiC power switches have been demonstrated with a blocking voltage from 10 kV to 24 kV. In addition to these gigantic improvements in voltage ratings, the switching speed of these devices is also significantly faster than Si IGBT. Utilizing the advanced SiC power electronic technology, medium voltage power electronics solution can now be developed to transform the legacy power grid to a smart and resilient grid that is not only efficient but also capable of integrating new energy resources and new types of loads. This talk will discuss the concept of the SiC based solid-state transformer (SST) and its applications.

Title: Protection of High-Voltage DC Transmission Systems

Abstract: High Voltage DC (HVDC) transmission is a long-standing technology with many installations around the world. Over the past few years, significant breakthroughs in the voltage-sourced converter technology along with their attractive features have made the HVDC technology even more promising in providing enhanced reliability and functionality and reducing cost and power losses. Concomitantly, significant changes in generation, transmission, and loads such as (i) integration and tapping renewable energy generation in remote areas, (ii) need for relocation or bypassing older conventional and/or nuclear power plants, (iii) increasing transmission capacity, and (iv) urbanization and the need to feed the large cities have emerged. These new trends have called for Multi-Terminal DC (MTDC) systems, which when embedded inside the AC grid, can enhance stability, reliability, and efficiency of the present power grid. The strategic importance of MVDC and HVDC grids is evidenced by the number of worldwide projects currently in their advanced planning stage, e.g., European “Supergrids” and the Baltic Sea project along with several projects in China. Amid the optimism surrounding the benefits of MTDC grids, their protection against DC-side faults remains one of their major technical challenges. Proper protection of DC grids calls for reliable, fast, and efficient DC circuit breakers (CBs). This presentation, first, focuses on the technical challenges associated with such CBs and their integration into the MTDC grids. Then, design and development of a new class of hybrid solid-state CBs, which compared to the state-of-the-art technology, substantially reduces steady-state losses as well as overvoltage and overcurrent stresses and allows a much faster switching time, is presented.

Title: Power Engineering Education in the Age of Climate Crisis – A Holistic View

Abstract: Climate change is the gravest threat facing humanity. Power engineering and its education have an important role to at least delay, if not avert, the catastrophes ahead. However, as reported by ASEE, in the EE part of ECE, student enrollments are declining nationwide just when we need them the most. Most young people are now very much aware of climate change and its consequences, and thus it is a great opportunity to create a pipeline of young students to recruit them into power engineering to pursue their undergraduate and graduate studies. This would require a holistic view where we integrate power systems that is needed for the delivery of power, power electronics that is ubiquitous and is used in all aspect of energy generation, transmission and end-use, and electric machines that are the primary users of electricity specially if we are to transfer as much of energy use to electricity and generate that by renewables. This presentation will present one view of doing such integration mentioned above and how can it be done in a collaborative manner using the educational technologies on hand.

Title: Microgrid Testbeds at Different Scales for Research and Education

Abstract: This talk will discuss the challenges of education and workforce development faced by the paradigm shift of power systems from electric machines-based to power electronics-based: the shortage of highly-skilled workforce, in particular, those equipped with broad ranges of expertise and hands-on skills in advanced controls, power electronics, and power systems. This requires universities worldwide to revise the power engineering curriculum and increase the amount of hands-on sessions with the shortest learning curve and the highest learning efficiency. We will share our experiences in building microgrid testbeds at different scales for both research and education. The underlying advanced power electronics control technologies adopted in these microgrids will be briefly discussed as well.

Title: Resilient Architectures and Algorithms  for Generation Control of Inertialess AC Microgrids

Abstract:  This talk discusses the problem of frequency regulation in islanded ac microgrids with no inertia, i.e., those consisting entirely of generators interfaced through power electronics. The control architecture we propose to achieve this is designed to drive the average frequency error to zero while ensuring that the frequency at every bus is equal and that the operating point that results is stable. We also introduce a distributed implementation of the proposed control architecture that relies on a combination of several distributed algorithms.  Collectively, these algorithms eliminate the need for a centralized entity with complete knowledge of the network, its topology, or the capabilities or properties of the generators and loads therein. Moreover, the distributed implementation we propose relies on minimal measurements, requiring only that the power injection at each bus be measured. Additionally, by eliminating the need for a centralized processor and a communication network connecting it to each generator, these distributed approaches can achieve higher system-level reliability, adaptability, and resilience.

Title: Nonlinear Decentralized Control for Future Grids

Abstract: In this talk, we will outline fundamental advances that link nonlinear control, circuits, and power systems. The aim is to show how nonlinear oscillator circuits can be used to realize digital controllers for grid-connected inverters. Experimental and analytical results reveal that these oscillators exhibit properties which enable decentralized control of highly distributed and complex inverter-based grids. Taken together, these features enable scalable, resilient, and robust power-electronics-based systems that align with future settings.

Title: High Frequency Power Electronics at the Grid Edge: Opportunities and Challenges

Abstract: A future electric grid with 100% renewable energy will be supported by billions of power electronics devices located at the grid edge. Medium-voltage solid-state-transformers with high frequency power conversion may serve as the energy router of the future grid. Hybrid multi-input-multi-output (MIMO) power conversion and energy storage systems can provide the needed “active” inertia for a future grid with very low “passive” inertia. The recent advance in wide bandgap (WBG) semiconductor devices and power magnetics opens opportunities to greatly increase the switching frequency of power electronics to reduce the size, enhance the control, and reduce the cost of power conversion systems. This talk will provide an overview of the recent development of high frequency grid-interface power electronics, and highlight a few opportunities and challenges which are associated with power electronics at the grid edge. Novel circuit topologies, system architectures, as well as control techniques will be discussed to foster holistic innovations at the interdisciplinary area of power electronics and power systems.

Title: Impedance-Based Evaluation of Stability Impacts of Inverter-Based Resources

Abstract: Fast controls and low overloading capacity of inverter-based resources (IBR) make them very different from conventional synchronous generation having slow controls and high overloading capacity. This mismatch has resulted in dynamic stability problems in modern power systems with high penetration of IBR such as control interactions, resonance, low inertia and frequency response adequacy, etc. It is difficult to predict and solve these problems because of the lack of accurate models of IBR using wide variety of controls from different manufacturers implementing both grid-following and grid-forming functionalities. This talk will present impedance-based methods for addressing these problems by characterizing IBR from their terminals and treating them as black-box. The talk will present major research and development efforts at NREL focusing on understanding the behavior and impact of IBR on stability using impedance measurements.
