Contemporary Short-Circuit Analysis of DC Systems: Components and System Models
Duration: 120 minutes
Abstract. The efficient and reliable design of DC systems is one of the main roadblocks to large-scale deployment of these emerging systems. Despite the fact that the DC systems were used in special applications for over a decade, the knowledge and lessons learned remained often in the application silos. This tutorial aims to bring the latest knowledge from academia on DC systems and their protection and fuse it with industrial experience. The tutorial will first give an overview of the protection components needed in the DC systems and the emerging design methods and criteria. It will also provide important information from the IEC standards that should be considered. Approximately half of the tutorial will be dedicated to using numerical simulations to analyze the severity of various short-circuits and the performance of the system during the fault. The state-of-the-art simulation approach will be applied to shipboard power systems. The use case will be used to demonstrate the lessons learned in designing and operating DC systems in the marine industry.

Solid-State Circuit Breakers – Discussion on Emerging Topologies, Challenges, and Applications
Duration: 90 minutes
Abstract. The solid-state circuit breaker (SSCB) is renowned for its ultra-fast fault tripping speed and arc-free current interruption, which are highly desirable for applications including battery energy storage systems, renewable energy systems, and DC microgrids. WBG power semiconductor devices (SiC or GaN power devices) further facilitate the popularity of SSCBs due to their superior performances, like low conduction resistance and high blocking voltage capability. In this tutorial, the speakers will discuss the potentials and opportunities of DC systems, SSCB technology, and the possible applications where SSCBs could find their living space. The emerging standards governing SSCBs will also be briefly outlined. In addition, barriers that limit the wide application of SSCBs will also be discussed. Although SSCB topologies seem simple and easy to design, some technological challenges still exist, which will be highlighted.

Emerging Power Converters Topologies for DC Buildings Applications
Duration: 90 minutes
Abstract. DC power distribution is gaining increasing attention in residential and commercial buildings due to its potential for significant energy savings — up to 30% by eliminating losses associated with reactive power and rectification needed in traditional AC systems. This shift towards DC grids for buildings not only enhances energy efficiency but also aligns with the growing adoption of renewable energy systems, increasing the self-consumption of buildings as energy can be generated and used on-site. The emergence of DC-powered buildings drives the need for new power conversion technologies, including DC-DC converters for photovoltaic (PV) systems, DC electric vehicle (EV) chargers, and grid-interface converters to integrate AC grid with DC electrical installations inside homes, offices, and other buildings. This tutorial will delve into emerging power converter topologies, offering detailed insights into their design, operation, and requirements for DC building applications.

Tutorial 4 - Components for Lighting in local DC Microgrids
Components for Lighting in local DC Microgrids
Duration: 90 minutes
Abstract. LEDification leads to significantly lower energy demand for lighting, which could be verified during the last 15 years, but power grids and power distribution is still designed to be compatible with traditional light source types and power demands. Considerations in other power-hungry building infrastructure and industrial applications led to the design of the DC-Supply Grid for these more demanding sectors. Lighting can benefit in two ways from following the DC considerations laid down by industry. First, seamless integration into existing DC grids allows savings in installation effort, transformation cost and planning volume. Next, DC integration of lighting allows a small saving in energy consumption (when done right) and component count. Thus, in terms of energy efficiency, but more in therms of resource efficacy and effort reduction, going for DC lighting is the obvious path.

Tutorial 5 - Resilient and Secure DC Microgrids
Resilient and Secure DC Microgrids: Decentralized Control, Stability, and AI-Driven Cybersecurity
Duration: 120 minutes
Abstract. In recent years, DC microgrids have gained increasing attention due to the widespread utilization of DC power sources, such as photovoltaics (PV), fuel cells (FC), and various energy storage systems (ESSs), and the increasing penetration of DC loads, such as computing devices, data centers, motor drive systems. Unlike their AC counterparts, DC microgrids avoid issues related to synchronization, reactive power flow, and harmonics. As a result, DC microgrids have been extensively deployed in renewable energy systems, high-efficiency households, and electrified transportation systems, including naval ships, spacecraft, aircraft, submarines, and electric vehicles. However, DC microgrids face challenges, including the critical demand-supply power balance under intermittent renewable generations, the stability issue emerged from the high penetration of power electronic converters, and vulnerabilities to cyberattacks due to the employment of communication systems. Moreover, the rapid advancement of artificial intelligence (AI) introduces both new challenges and opportunities for its application in DC microgrids. This tutorial will explore decentralized power management strategies, stability analysis and stabilization strategies, and AI-enabled cybersecurity framework to address the stability and cybersecurity issues in DC microgrids. The tutorial will begin with an overview of control strategies for DC microgrids. Next, decentralized power management strategy is developed for hybrid energy storage systems to compensate for power fluctuations. In addition, stability analysis and stabilization methods are introduced. Finally, machine learning-based cyber-attack identification and detection framework is developed to enhance the cybersecurity of DC microgrids.

Microgrids: Modeling, Stability and Control
Duration: 120 minutes
Abstract. The microgrid concept provides an effective solution for integrating renewable energy sources and distributed energy resources (DERs) into power grids. Microgrids are small-scale systems that interconnect customers, DERs, and storage, serving as key components of modern power grids. Their ability to operate in grid-connected and islanded modes enhances resilience and energy efficiency. This tutorial covers the modeling, stability, and control of microgrids, focusing on off-grid applications. It begins with a comparative analysis of DC vs. AC microgrids, discussing their advantages, challenges, and suitability for various applications. The tutorial then explores microgrid dynamic modeling, including small-signal and nonlinear modeling techniques and methods for interconnecting sub-models for efficient simulation. Microgrid stability is addressed, covering stability classification methods and small-signal stability analysis techniques such as eigenvalue analysis and sensitivity analysis. Key parameters affecting stability are examined. The session also addresses transient stability and power-sharing challenges in AC MGs and stability enhancement techniques for DC microgrids. The control of microgrids is explored, with a focus on hierarchical control structures and strategies for stable and cost-effective operation in both modes. Linear and practical control solutions are highlighted. This tutorial offers a comprehensive understanding of microgrid structures, dynamics, stability, and control, supported by theoretical analysis, simulations, and practical examples, making it valuable for researchers, engineers, and practitioners in smart grids and power electronics.
