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.

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.

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.

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.

Supercapacitor techniques for protecting future DC systems, DC appliances and DC microgrids: New Zealand experiences with FAN project outcomes  

Duration: 120 minutes 

Abstract. DC systems are proliferating as the renewable energy systems are propagating rapidly. Reliability of these systems are dependent on two main factors (a) energy storge to buffer fluctuations of renewable energy (b) protection against transient over-voltages and over-current situations. Traditional and common energy storge systems are based on rechargeable battery systems. However, the battery systems come with short life cycles and environmental issues. Within the last two decades supercapacitors (SC) have emerged as an alternative to batteries for limited applications where lower energy density of SCs are acceptable. Within the last two decades University of Waikato power electronics research team has come up with a unique set of power converters and protection systems based on supercapacitors which are now known as Supercapacitor Assisted (SCA) techniques. SCA surge absorbers are one of the successful techniques to protect systems against lightning and transient inductive voltage surges. Within the last 5 years they have joined the Future Architecture Network project funded by the NZ govt and expanded their work to develop SCA protection techniques such as SCA- DC circuit breaker. This tutorial will present the unique properties of commercial supercapacitor families and how these new device families could be used beyond simple energy storage and design transient over-voltage protection systems and transient over current protection systems.
