Transmission System – The Interconnected Bulk Electric System
Instructor: Douglas A. Bowman, Southwest Power Pool Description: (Prerequisite for this course is Power System Basics or a familiarity with basic formulas and power system equipment.) The focus of this course is to provide participants with knowledge of how electric power is transferred from generation sources to distribution systems via the interconnected electric bulk power system known as “the grid.” Basic physical laws governing the grid will be introduced, as well as the regulatory agencies involved in its governance. The great blackouts will be explored. This course is intended to increase participant’s understanding of the electric grid and how it functions in the electric power system. Topics covered in the course include an introduction to the fundamental concepts of power, energy, and power system stability as they relate to the grid. The grid is explored in terms of its interconnections, power flow, North American interconnections, and governing bodies such as NERC/ERO, ISOs, and RTOs. Reliability standards and contingency analysis are addressed. Issues related to the planning and operation of the grid, such as transmission and economic constraints, determining transmission transfer capability, and dealing with congestion are reviewed. The course also discusses the great blackouts, their root causes, and lessons learned.
IEEE PES Live Online: Modeling and Stability Analysis of Inverter-based Resources
Presented by: Dr. Lingling Fan, University of South Florida This one-hour webinar will present a few highlights of a recently published book: L. Fan, Z. Miao, Modeling and Stability Analysis of Inverter-Based Resources, CRC Press 2023. The webinar will be useful for undergraduate and graduate students who aim to learn dynamic modeling of inverter-based resources (IBRs), converter control design, stability analysis, and electromagnetic transient simulation (EMT). This talk focuses on a few highlights of the book: 1. Per unit-based computation and parameter configuration for converter controls – this approach facilitates developing engineering intuitions and insights. 2. Testbed building and control validation through EMT environments. Different from many programming-intensive approaches, EMT environment makes testbed building easy and bug free, saving us tremendous time to focus on analysis instead of entangled with numerical integration, coding and debugging. 3. Feedback system analysis –By thinking in feedback systems, we naturally conduct simplification based on needs. It is no surprise that control design and control implementation should be treated separately. This separation simplifies the task of controller parameter tuning. In summary, dynamic modeling and analysis is intriguing and full of fun, if the above strategies are adopted.
