A short/mid-term power system dynamic simulation is formulated with detailed models of generating plant and nonlinear loads. A linear network model is used and an outline of the computational algorithm for its solution is given. In the formulation of the models of dynamic components, a modular approach is adopted which facilitates the partitioning of the power system. Included is the solution of the set of nonlinear algebraic and differential equations which describes the dynamics of a power system. The numerical problems in time integration such as the treatment of discontinuities, control of round-off and truncation errors, and numerical stability are discussed, and various approaches are investigated
