Power system simulation models are a class of computer simulation programs that focus on the operation of electrical power systems. These computer programs are used in a wide range of planning and operational situations including:
- Long-term generation and transmission expansion planning
- Short-term operational simulations
- Market analysis (e.g. price forecasting)
These programs typically make use of mathematical optimization techniques such linear programming, quadratic programming, and mixed integer programming.
Key elements of power systems that are modeled include:
- Load flow (power flow study)
- Short circuit
- Transient stability
- Optimal dispatch of generating units (unit commitment)
- Transmission (optimal power flow)
Layered on top if this physical framework are models of competition such as Cournot, Bertrand competition, and Supply Function Equilibrium. Before the advent of large scale digital computers, power system simulation was carried out on network analyzers, which were essentially miniature scale models of power systems with scaled generators, loads, and line simulators.

Famous quotes containing the words power, system and/or simulation:
“To get power over is to defile. To possess is to defile.”
—Simone Weil (1909–1943)
“I need not say what match I would touch, what system endeavor to blow up; but as I love my life, I would side with the light, and let the dark earth roll from under me, calling my mother and my brother to follow.”
—Henry David Thoreau (1817–1862)
“Life, as the most ancient of all metaphors insists, is a journey; and the travel book, in its deceptive simulation of the journey’s fits and starts, rehearses life’s own fragmentation. More even than the novel, it embraces the contingency of things.”
—Jonathan Raban (b. 1942)
