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:
“I have no hesitation in saying that although the American woman never leaves her domestic sphere and is in some respects very dependent within it, nowhere does she enjoy a higher station. And ... if anyone asks me what I think the chief cause of the extraordinary prosperity and growing power of this nation, I should answer that it is due to the superiority of their women.”
—Alexis de Tocqueville (1805–1859)
“Social and scientific progress are assured, sir, once our great system of postpossession payments is in operation, not the installment plan, no sir, but a system of small postpossession payments that clinch the investment. No possible rational human wish unfulfilled. A man with a salary of fifty dollars a week can start payments on a Rolls-Royce, the Waldorf-Astoria, or a troupe of trained seals if he so desires.”
—John Dos Passos (1896–1970)
“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)
