Modern power systems are operated much closer to their stability limits owing to economical and environmental constraints. Deregulated operation has increased variability of loading patterns many folds compared to limited operating scenarios of vertically integrated power system. In the existing operational environment, online monitoring against possible voltage collapse has become all the more important...
Economic Load Dispatch is one of the most important tasks to be performed in the operation and planning of a power system that decides the generation schedule of generating units with an objective of minimizing the total fuel cost. Normally, the fuel cost of generators can be treated as a quadratic function of real power generation. In fact, valve point loading effect in thermal power plants introduces...
