ABSTRACT
Power system operating or control decisions involve taking into consideration possible impacts on power system reliability and environmental performance. Possibly the best way to begin to understand operating economics and the related issues of control, reliability, and environmental performance is to begin by considering a power system consisting of a single generating unit attached to a single variable load. After this, a power system with multiple generating units is considered, and the classical “economic dispatching” problem and the classical “unit commitment” problem defined. A power system consisting of a single generating unit attached to a single variable load is considered. Of course, in actual power systems, power generators generally have three-phase output voltages in the range of 10 to 24 kV, and it is necessary to use step-up transformers to reduce the losses associated with long-distance transmission.
