Description

In this course, explore the design principles and practical applications of modern energy management systems, Independent System Operators (ISOs), and Regional Transmission Organizations (RTOs). You will examine hardware, software, communications, and user interfaces. Develop a clear understanding of the philosophy of modern power system operations and the role of energy management systems, their design, and actual implementation. You will survey past and current practices, as well as trends in the state-of-the-art design of energy management systems. You will also discuss new requirements imposed by deregulation, open access, and competition.

What You Will Learn

  • Modern energy management systems
  • State estimation
  • Economic operation
  • Network security
  • The smart grid
  • Modern scada systems
  • Distribution management system
  • Practical overview

How You Will Benefit

  • Study the control and operation of modern power systems.
  • Review hardware architectures (SCADA, IEDs, computers, and communication components), communication software, applications software, and user interfaces.
  • Examine real-time control functions performed by modern energy management systems.
  • Review modern user interfaces and visualization methods and discuss new needs and emerging practices imposed by deregulation and open access.
