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.
