As the State with the largest production of electricity and the largest commercial hydrogen infrastructure, the Texas industry is actively exploring effective synergies. The tutorial will begin with an introduction to hydrogen to provide a common understanding for the remainder of the presentations. The talks and panel discussions will describe how the production, use, and storage of hydrogen have the potential to improve and decarbonize power system operations. Technical, cost, and regulatory realities will be highlighted to provide a perspective on what are short-term opportunities and what are likely many longer-term possibilities.

There is a consensus in the industry that deep decarbonization in the electric power system will not be achieved without a combination of storage technologies, with durations ranging from short-term to emerging, advanced long-term technologies. This decarbonizing the power system will likely require high penetration of variable renewable technologies such as wind in solar. The intermittent nature of these technologies, at high penetration levels, has the potential to create gaps in power delivery. These gaps can be from short-term fluctuations with over/under supply, or long-term issues related to weather patterns. Energy storage can fill these gaps with technologies that can align with each of the power gaps that may arise when efforts to decarbonize the power sector lead to renewable penetration levels in the range of 70-100%. Hence, this tutorial will focus on energy storage technologies and help participants understand storage technologies and how best to apply short-term and long-term technologies to the challenges created by high penetration of renewables. The tutorial will help attendees understand all aspects of short and long-duration storage in a session that covers (1) technologies – short and long duration, (2) challenges created by high penetration of renewables, (3) applications for energy storage and markets that can support those technologies in a deeply decarbonized power system, (4) latest updates on standards for deploying storage, and (5) a review of safety issues with the technologies.

This tutorial introduces the audience to the mathematical background and the implementation of distribution systems dynamic models within open-source power system simulators in the frequency domain. The mathematical content of this tutorial is reviewed for the audience’s awareness of the existing models for representing traditional equipment, such as synchronous machines, and non-traditional devices, such as Inverter Resources (IBR). This introduction will reveal the constraints and requisites for their implementation in computational simulation tools. The implementation of both traditional and non-traditional equipment will be examined using EPRI’s open-source distribution system simulator, OpenDSS, describing the sequence of events for obtaining a successful dynamic simulation, which later is verified with a practical example.

Global concerns for sustainable decarbonization encompass all sectors including the maritime one which comprises inter alias ships and their hosting places, ports. Thus, the decarbonization of inland power grids needs to comply with the maritime one and serve one another in a mutually beneficial way. Within this context, electrification is proven to be the ultimate means, esp. in the case of “shore-to-ship” electrical interconnection (often met as “cold ironing”) which means that the ships while at berth in ports, shutdown their engines and are supplied from the inland Grid, the energy of which is based on environmental friendly Renewable Energy Sources (RES). Major challenges consist of the huge amounts of power a ship needs (varying from 200 kW up to 15 MW) as well as voltage transformation, frequency conversion, and earthing compatibilities. Anyhow, the existing or under-development-related technology is proven to, from the maturity point of view, be readily available. This maturity is enriched and supported via the set of IEEE standards for ships (IEEE 45.1-.8 series developed within IEEE/PES/MSCC), while for ports with ship interconnections (IEC/ISO/IEEE 80005-1/2/3). Moreover, IEEE/EPPC has just launched a new policy document on “smart and sustainable ports” providing the roadmap towards the successful implementation and operation of the decarbonization of ports, while the ICA-22-13 keeps identifying gaps and missing links. Hence, the tutorial aims at presenting the partial objectives of the electrification of ports in terms of planning from the TSO and DSO point of view, designing the high-power networks needed and integrating them into the existing infrastructure of the ports as well as connecting them to the main Grid, operating them via well-trained personnel and using appropriate business models with viable pricing policy of electricity while complying with the free market frameworks. Within this context, the specificities of the emerging challenge of port electric distribution networks in combination with modern ship electric networks will be analyzed and discussed. In all cases, the parallel developments of power grids (smart grids, microgrids, smart metering, flexibility, demand side response, and resilience) will be commended.

As utilities around the world begin to explore the potential of IEC 61850 through pilot projects, this standard is emerging as a key enabler for modernizing substation protection, automation, and control. IEC 61850 offers unparalleled interoperability, flexibility, and scalability, transforming how utilities design, manage, and upgrade their systems. This tutorial will provide a comprehensive introduction to the fundamentals of IEC 61850, explaining its core principles, including object modeling, the communication stack, and key communication services. Attendees will learn about the benefits of interoperability that IEC 61850 brings to digital substations, such as reduced engineering efforts, increased system reliability, and seamless multi-vendor integration. Additionally, we will explore the practical challenges of implementing IEC 61850. The tutorial will offer actionable insights on how attendees can apply these concepts to their systems, helping to modernize operations while ensuring future-proof scalability, performance, and reliability.

State Estimator technology has been in use in Control Centers for over 3 decades. It is still a challenge to support the State Estimator (SE) 24 x 7 due to its critical role in ensuring Grid reliability and in supporting operational decision-making tools in real-time, more so due to the extensive penetration of renewables. Due to its scope and complexity, it is still perplexing to many who are involved in supporting the tool. The tutorial provides several key aspects including the criticality of SE, the extent of network model choice of detail, solution quality, tuning, and 24 x 7 support system all of them in a nutshell. This tutorial provides a basic understanding of State Estimator as used in the industry, its criticality in control centers in operating the grid reliably and provides insights into industry practices to support 24 x 7 and provides the challenges due to renewable penetration. This tutorial is taught by industry practitioners beginning as frontline engineers and managing the technology over years of experience. The tutorial is suitable for students, engineers, managers, and researchers to provide support and practical solutions.

The IEEE Std 2800 was published in April of 2022 which specified technical minimum capability and performance requirements for Inverter-Based Resources. This tutorial will provide insights into the origination, details, interpretation, and application of some of the included requirements in the standard. Some lessons are learned as the industry adopts this standard and the corresponding recommended practice for test and verification procedures are being developed in IEEE P2800.2. This tutorial will also highlight these lessons learned which may inform the next revision of the standard. This may include example requirements that may need further clarity and requirements that may need to be fully revised. An informed audience may help in the faster adoption and timely revision of this standard.
