Generalized Generation Distribution Factors for Power System Security Evaluations

A set of Generalized Generation Distribution Factors (GGDF´s) is developed to replace the conventional Generation Shift Distribution Factors (GSDF´s). This model relates the line flows with generations for a given network configuration. Being in an integral form, new flows on lines can be obtained directly without running load flows when total system generation changes. Conforming load change is also demonstrated. These new factors are especially suitable for constraint formulation in mathematical programning, such as optimal generation dispatch with security contingencies considered
