Tutorial 1A
Title: Infrastructure Asset Management with Power System Application and Tools (Part A, Part B)
Summary:
The electric power system is in a huge transition to enable sustainable developments and meet goals for circular economy. New developments include possibilities and challenges with the generation, delivery, and usage of electricity as an integrated part of the energy system. At the same time, the digitalization of society is creating new opportunities for control and automation as well as new business models and energy-related services. The overall trend for technology developments is new possibilities for measurement and control. An example is Phasor Measurements Units (PMUs), generally located in the transmission network, which provide measurements of voltage and current up to 30-120 times per second. Another trend is the development of diagnostic measurement techniques for assessing the insulation condition and prediction of the life of physical assets, and new methods for condition monitoring. These different trends have in common an overall development towards access to large volumes of data for handling and analysis which provides new means for infrastructure asset management (AM).
This tutorial will include three parts. Firstly, an introduction to AM providing definitions, terminology, and basic theories. This part of the tutorial will include a detailed presentation of the reliability-centered maintenance (RCM) framework and the proposed quantitative method of reliability-centered asset management method (RCAM). Secondly, a set of examples from a wide range of applications for the electric power system and its components will be presented including recent results from a CIRED working group on Life time extension of electrical equipment. Finally a computer tool will be presented for novel AM of electrical equipment resulting from the EU project ATTEST and an open source tool for AM using machine learning algorithms.
Prof Lina Bertling Tjernberg and Mr. Gopal Lal Rajora will be the speakers for this tutorial.

Title: Reliability in Power Electronics -Dominated Power System (Part 1, Part 2)
Summary:
Power electronics are the underpinning part of future power systems. Reliability as the long-term performance indicator is of paramount importance for design and manufacturing of power electronic converters in different applications, in particular for design and planning of future power grids with dominated power electronic devices. This tutorial aims to address the basics of reliability modeling, evaluation and enhancement taking into account the physics of failure mechanisms from device-level up to system-level in power electronic systems. Model-based hierarchical reliability assessment and enhancement in power electronic based power systems will be presented. Different applications including microgrids, PV systems, wind systems, etc. will be discussed. This will help both power electronics and power system engineers to design, strengthen, and maintain power electronic converters as well as to perform optimal planning and operation of modern power systems.

Tutorial 2A
Title: Reliability Evaluation of Active Distribution Systems
Summary:
With the penetration of large-scale distributed generation into the distribution grid, the traditional distribution network has gradually transformed into an active distribution network. The active distribution network is a complex distribution system composed of loads, various distribution generations, energy storage, energy conversion devices, and monitoring and protection devices. The traditional reliability assessment model and method are significantly influenced, and there are a variety of challenges in the reliability assessment of active distribution networks.
This tutorial introduces reliability assessment techniques for the distribution grid, including renewable generations' uncertainty and failure probability. It is designed for graduate students and post-doctorate fellows and will mainly include the following sections:
• Reliability block diagrams and approximate system reliability evaluation in a traditional distribution grid,
• Distribution system reliability indices
• Reliability assessment for (passive) radial distribution feeders
• Reliability assessment of distribution feeders comprising renewable generation and energy storage units.
• Inclusion of renewable energy uncertainties in reliability assessment.

Tutorial 2B
Title: Managing Uncertainty in Load Forecasting: An Australia – New Zealand Case Study
Summary:
The tutorial session aims to provide a comprehensive overview of the challenges and strategies associated with handling uncertainty in the context of load demand forecasting. The session will delve into the critical importance of accurate load forecasting and demand trends while exploring the various sources of uncertainty, such as weather forecasting errors, economic/policy changes, and unforeseen events. Participants will gain insights into state-of-the-art forecasting models, data analytics techniques, and methodologies designed to enhance load forecasting accuracy in the face of uncertainty. Practical case studies and real-world examples from Australia and New Zealand will be presented, illustrating the impact of uncertainty on forecasting outcomes and showcasing effective strategies for uncertainty quantification. The tutorial will feature a live demonstration showcasing the tools used by various stakeholders, including system operators and energy traders, to manage uncertainty. Through interactive discussions, participants will examine the limitations of current forecasting models and explore avenues for future research and improvement. The tutorial will also introduce probabilistic load forecasting and explain how to evaluate them. Overall, the tutorial aims to equip electrical power system professionals with practical insights into effectively managing uncertainty in load forecasting, setting the stage for ongoing exploration and innovation in this critical aspect of power system operations.
