Jay Giri

Jay Giri

Jay Giri, PhD is Director of Power Systems Technology and Strategic Initiatives at GE Grid Software Solutions in Redmond, Washington, USA. He is a group manager for engineers who deliver software applications to utility control centers for: electricity market systems, generation monitoring and control and synchrophasor/phasor measurement unit (PMU) analytics. He is a liaison for university research activities and an affiliate professor at the University of Washington. Jay and 11 other engineers co-founded Energy System Computer Applications (ESCA) in 1978. After numerous corporate mergers, ESCA became part of GE Grid Software Solutions in 2015. Jay designed and implemented the original software for the ESCA automatic generation control (AGC) and dispatcher training simulator (DTS) power system simulation functions. Today this AGC controls over 50% of North American generation as well as generation in many other countries, and the DTS is one of the predominant simulators used by control centers worldwide.

He has a PhD from Clarkson University in New York and a B.Tech from the Indian Institute of Technology (IIT), Madras. He was elected IEEE Fellow: “For contributions to the design and implementation of power system control centers” in 2002. Since 2011, Jay has been a member of the IEEE Power &Energy Society (PES) Governing Board – now focussing on Industry Outreach. Jay was appointed Alstom Grid Senior Fellow in 2013 and a member of the Washington State Academy of Sciences in 2015.

Executive Vice President, Open Access Technology International (OATI)

Title: Secure Visibility and Control

The US energy sector is one of the most targeted industries in the world for cyber-attacks. Any device with an IP address can potentially be hacked, and these odds increase dramatically when Smart Grid systems are poorly protected. This presentation covers these security challenges and demonstrates that technological capabilities exist today that can prevent these threats by creating a highly secure connected grid.

Kash has been with OATI since the company was founded 20 years ago. He has been engaged in various product developments and in recent years in Smart Grid applications, Grid Secure connection, and Microgrids. He received his BS, MS, and Ph.D. degrees in Electrical Engineering from Iowa State University in Ames, Iowa.

Dr. Vahid Madani

Title: Synchrophasor Systems and Wide-area Control

With nearly 2 years since large scale deployments of synchrophasor systems have gone into production and data streaming into control centers in place in many parts of the world, discussions on deployment of production grade open and closed loop control applications are gaining renewed grounds. At the same time, the academic initiatives have been continuing in several areas. Control functions generally involve assets of one or more power company depending on the measurements and purpose of the scheme while synchronized measurements data may be based the application for the respective business case. This presentation is focused on technical and functional requirements and business case drivers and for such applications including control-oriented dynamic models, data quality, and supervisory functions for successful implementations closed loop controls, and a discussion on the initial types of feasible and practical applications.

Dr. Vahid Madani is a Principal scientist and protection and control Engineer for advanced power systems applications at Pacific Gas & Electric Co., headquartered in San Francisco, California, USA. His experience spans across System Planning, Operation, Protection and Control Engineering, Asset Strategy and Compliance.

An industry leader, Vahid contributes to innovation and maturing technologies for grid modernization while maintaining reliable service to more than 16 Million Customers.

Dr. Madani has many publications and has co-authored text books and reference handbooks. He is a Fellow of IEEE and an IEEE PES Distinguished Lecturer and has many publications and citations and awards from IEEE and the US DOE.

Title: Wide-Area Transmission System Data Analysis and Visualization

The installation of vast quantities of additional new sensing and communication equipment, in conjunction with building the computing infrastructure to store and manage data gathered by this equipment, has been the first step in the creation of what is generically referred to as the Smart Grid for the electric transmission system. With this enormous capital investment in equipment having been made, attention is now focused on developing methods to analyze and visualize this large data set. One direct use of this large set of new data will be in data analysis and visualization. This presentation covers some of the newer techniques that have been deployed for visualizing this data. These techniques include display animation, contouring, time-varying graphs, geographic based displays, image blending, and data aggregation techniques.

Thomas J. Overbye is currently the Fox Family Professor of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign (UIUC). He received his BS, MS, and Ph.D. degrees in Electrical Engineering from the University of Wisconsin-Madison. Prior to joining UIUC he was employed with Madison Gas and Electric Company. Dr. Overbye is the original developer of PowerWorld Simulator, an innovative, widely used software package for power system analysis and visualization, a co-founder of PowerWorld Corporation, and is a member of the US National Academy of Engineering.

Title: Advances in Integrating Synchrophasors into Modern Energy Management Systems and Grid Operations

The utility industry at large has made significant investments in deployment of production grade Wide Area Monitoring Systems (WAMS) and synchrophasor technology in recent years with now well over 4,000 Phasor Measurement Units (PMUs) globally. In North America alone the PMU installations have expanded from approximately 200 research-grade units to over 1,700 production-grade devices in less than five years. The growth is further expanding to large scale generation units as well as distribution systems. A wide range of PMU measurement-based analytics such as model validation metrics, post event analytics and power system performance signatures, oscillatory stability monitoring, islanding detection and resynchronization, system disturbance characterization are now available for System Planning, Operational Engineering, and real-time operation use.

As utilities look at operationalizing synchrophasor application, improving PMU data quality, providing operator guidance on the new synchrophasor applications, having an effective training program for operators, and arming operations and planning engineers with offline analysis tools, are some of the common hurdles that have been identified in operationalizing this technology. GE along with our utility partners has been collaborating on augmenting the existing PMU measurement-based analytics within the synchrophasor platform with model-based analysis and simulation capabilities available within today’s Energy Management Systems (EMS) and Dispatcher Training Simulator (DTS) to overcome these challenges, and help transition the technology into Grid Operations.

Manu Parashar is the Senior Software Manager, responsible for the Wide Area Monitoring Systems (WAMS) and Grid Stability product line at GE Grid Solutions (formerly known as ALSTOM Grid Inc). He has been involved in the Research and Development activities of GE’s Stability Solutions, including synchrophasor applications, and was the technical lead in delivering these applications to the North American customers. Prior to joining GE, he was with Electric Power Group where he was responsible for all synchrophasor related research & development initiatives, including leading the development of the real time and offline synchrophasor applications. Manu received his BS, MS, and PhD degrees in Electrical Engineering from Cornell University, Ithaca, NY, in 1997, 1999, and 2003, respectively.
