Security-constrained multiobjective generation dispatch using bicriterion global optimisation

The paper is devoted to the dynamic performance assessment and model reduction for longitudinal interconnected power systems. Based on this, simple expressions are established to represent variations of security levels with the power transfer between subsystems. These expressions are used to extend the authors´ work on a bicriterion optimisation approach for determining the most appropriate generation-dispatch solution taking into account the fuel and environmental costs, and to provide security constraints/checks during optimisation
