Energy and Power Systems: The Big Picture
Understand how primary energy becomes electricity, how electric power moves through networks, and how supply must continuously match demand.
Where this fits
Understand how primary energy becomes electricity, how electric power moves through networks, and how supply must continuously match demand.
Core system ideas
Energy is the ability to do work, while power is the rate at which energy is transferred or used.
Electricity is an energy carrier produced by converting primary energy sources and delivered through generation, transmission and distribution systems.
The power system is a synchronized network: generation, networks, storage, demand, controls and markets or operating rules all interact.
Interfaces and tradeoffs
The most useful way to understand this topic is to place it in the chain from energy conversion to customer service. Definitions, units and system boundaries should be explicit before comparing technologies.
What organizations measure
Energy, power, peak demand, generation output, losses, reliability and service interruptions.
