Energy System Modeling
How simplified mathematical representations help explore power-system behaviour and planning scenarios.
Systems note: terminology, market structures, voltage classes and reliability rules vary by jurisdiction. Use current local standards and utility information for real projects.
Where this fits
How simplified mathematical representations help explore power-system behaviour and planning scenarios.
Core system ideas
Models deliberately simplify reality to answer a specific question.
Capacity-expansion, production-cost, power-flow and stability models operate at different timescales and levels of detail.
A model should be validated against observed data and its assumptions documented.
Interfaces and tradeoffs
Planning uses scenarios because demand, resource additions, retirements, weather, project timing and technology are uncertain. Models are decision aids rather than perfect predictions.
What organizations measure
Model error, scenario range, sensitivity, constraints and validation.
