EE362G Smart Grids: Introduction Ross Baldick, Department of Electrical and Computer Engineering Spring 2019 Copyright © 2019 Ross Baldick

Outline Definition of smart grid. Course overview. Homework exercise. Copyright © 2019

Definition of smart grid. Application of information and communication technologies (ICT) to the power grid. Smart grid discussions are often focused on the distribution system, Consistent with the US Energy Independence and Security Act of 2017, we will initially take a more expansive definition of “grid:” Include transmission and generation, Include end-use of electricity.

Definition of smart grid. Long-standing applications of ICT to the generation and transmission system include: Supervisory Control and Data Acquisition (SCADA) Systems, which provide telemetry of generation and transmission data and control of bulk generation and transmission assets (beginning 1970s), Energy Management Systems (EMS), including Independent System Operator EMS in restructured markets.

Definition of smart grid. More recent additions to transmission system monitoring: Phasor measurement units, Telemetry of temperature and related measurements of transmission lines. Generation and transmission-related ICT is not typically obvious to end-users. Copyright © 2019

Definition of smart grid. Smart grid has received considerable hype: Particularly regarding end-user implications. We will endeavor to clarify various concepts: smart grid, self-healing grid, microgrid, digital grid. Evaluate costs and benefits. Copyright © 2019

Homework Exercise: Due Thursday, Jan. 31. 1 a) Without looking at a dictionary or a search engine, define what you would mean by “self-healing.” You might use an example in terms of healing of a cut or wound, but try to make the definition generic. b) Use a search engine to obtain a definition of “self-healing grid.” Avoid circular or self-referential definitions such as “a self-healing grid is a grid that can heal itself.” Define specifically what is meant by the webpages that refer to self-healing grid. c) Compare the two meanings of self-healing. Is the definition of self-healing grid a reasonable one, given your prior understanding (as described in part a)) of what it generically means to be self-healing. d) Find as many definitions as you can of: (i) smart grid, (ii) microgrid, (iii) digital grid.
