Introduction to Electricity Markets

2.0 Introduction

PrintPrint

In the previous lesson, you learned that the North American power grid is an immensely complex machine capable of delivering electricity over many hundreds of miles, and a lot of different technologies and fuels are used to produce the power that we use every day. In this lesson we'll get deeper into the physics of how electricity moves through the transmission grid from the power plant to your home or business. This trip through the physics of electric power transmission is not a detour. It is actually one of the most important lessons in the whole course, because electricity has some physical properties that make it very different from other energy commodities like crude oil or coal. These physical properties make it possible for huge electric power grids to be economical, but also make it very hard to design commodity markets for electricity.

Learning Outcomes

By the end of this lesson you will be able to:

  • Describe the difference between electric power and electric energy, and provide appropriate units for each.
  • Identify the most important physical quantities associated with electric power production.
  • Calculate equivalent resistances for series and parallel circuits.
  • Calculate power transfer distribution factors for electric transmission grids.
  • Solve power flow problems in two-node and three-node networks.
