Modern Energy Management Systems

Course 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.
