Transmission Planning Course

How to integrate a long-term view to the development of transmission systems? This is the challenge of transmission planning: to take into account future uncertainty, new power technologies and economic and operating realities in order to come up with a plan for transmission development.

In the new and emerging competitive markets, transmission planning needs to demonstrate relevance by providing applicable solutions to anticipated problems. In doing so, planners must provide answers to questions that have not yet been asked.

We will cover the various methodologies that have been tried, and point out the ones that work, and don’t work in the new competitive environment. We will discuss the methodologies for developing the strategic plan, and software-based approach to developing the implementation plan. We address the least-cost methodology, and how this is applicable to modern power systems. Finally, the course will discuss the possible future impacts in increasing penetration of renewable energies into the bulk power system, how to address them and how to plan for them.

Understanding Location-Based Energy Pricing

Nodal pricing is the emerging method for determining the impact of transmission congestion and losses on the price of electric energy. The method involves an optimization solution of costs subject to transmission constraints. This method bears more resemblance to the power flow than to a bidding program. Nodal pricing is applied, in varying forms, to energy markets, congestion rents, firm transmission rights, and others. For anyone participating in such markets, understanding the fundamentals of nodal pricing is a must.

This course provides an introductory coverage of the basics of modeling and calculating nodal pricing, starting from power flow models and cost curves. Case studies and exercises help bring home the concepts while providing real-life examples. The investment of your time and focus will surely be rewarded with a jump start on this important concept of nodal pricing.

Aspects of Underground Power Cable Systems Course

Utilities, architect-engineers, developers and industrials are often faced with considering an underground cable option either as a portion of an otherwise overhead line, to connect nearby substations, as entry to an already congested substation, or in urban setting where underground transmission or distribution is the only alternative. The student attending this course will gain an overall understanding of the major cable system types including extruded, self-contained fluid-filled and pipe-type, as well as an understanding about elements of design, manufacturing, installation and operation of underground transmission and distribution cables. More often, transmission cable systems are engineered on a case-by-case basis, so much of the 3-day course focuses on transmission with relevant references to distribution voltage cables. The instructor will discuss topics that are relevant for both voltage classes.

Linear Power Flow Analysis and Applications

In the accelerated environments of today’s electric energy markets, fast analyses of power flows are a must. Emerging real-time and day-ahead markets require that analysis of infrastructure capacity be performed in a compressed timeframe. In this context, approximate but fast and consistent power flow solutions are preferred over accurate but unwieldy ones. Hence, the increasing popularity of linear approximations to the power flow. The reason for widespread use may have to do with the fact that linear methods are much easier to apply, are not subject to convergence issues, and require less data.

In this introductory course, learn about the technology of linear power flows and apply them to real-world practical problems. Use this technology in applications such as anticipatory analysis of pricing and demand signals, transactional analysis of power interchange and delivery, transmission loading relief and feasibility analysis. In addition, learn about the limitations to these methods and the pitfalls to watch out for when applying these methods. Come away with a working knowledge of the technology of linear power flows.

CO2: Dynamic Simulation Analysis and Applications

Power system stability is an essential aspect of modern power systems. The assessment of stability, both transient and voltage, requires a detailed representation of control response from power system equipment in the millisec to minutes timeframe. The time-domain dynamic simulation is the basic tool for stability assessment. We will introduce the basic concepts of stability and dynamic simulation and illustrate them through hands-on case studies. We will use commercial software for instruction and provide coaching for the software you actually use at work. Come away with a stronger understanding of stability and the use and application of dynamic simulators.

CO3: Developing User Models for Dynamic Simulation

From time to time it is necessary to develop user models for equipment which do not have representation in commercial software packages for stability assessments. Emerging technologies and new equipment are typical bases for user models. This course introduces the basis for dynamic models, the range of responses they are intended to simulate, and then goes right into the mechanics of developing your own dynamic model.

Learn about power system controls and how these can be translated into special user models that work with today’s commercial simulation software. Be able to write your own models, debug other’s models and modify an existing model to suite your analytical needs. This is an advanced applications course. It is recommended that participants have prior experience with dynamic simulations and software programming to gain the most benefit from attending this course.

CO5: Applications in Voltage Stability

The industry, by experience and research, now understands more about voltage stability than it did just a few short years ago. Phenomena such as slow and fast collapse, the voltage ledge, self-restoring loads and composite load-voltage relationships have become a part of the practical operating experience rather than abstruse theoretical concepts. The course brings you to the actual indicators, analytical methods and operating bases for voltage instability, still based on sound theory, but focused on models, measurements and controls that are rooted in the practical power system. Speak and apply voltage stability with a new confidence with knowledge you bring to work from this course.
