Introduction to Optimal System Operation: The optimal system operation, in general, involved the consideration of economy of operation, system security, emissions at certain fossil-fuel plants, optimal releases of water at hydro generation, etc. All these considerations may make for conflicting requirements … (Read More)

Optimal Operation of Generators on a Bus Bar: Optimal Operation of Generators on a Bus Bar – The major component of generator operating cost is the fuel input/hour, while maintenance contributes only to a small extent. The fuel cost is meaningful … (Read More)

Optimal Unit Commitment (UC): As is evident, it is not economical to run all the units available all the time. To determine the units of a plant that should operate for a particular load is the problem of unit commitment (UC). … (Read More)

Reliability Consideration in Power System: With the increasing dependence of industry, agriculture and day-to-day household comfort upon the continuity of electric supply, the Reliability Consideration in Power System has assumed great importance. Every electric utility is normally under obligation to provide … (Read More)

Optimum Generation Scheduling: Optimum Generation Scheduling – From the unit commitment table of a given plant, the fuel cost curve of the plant can be determined in the form of a polynomial of suitable degree by the method of least squares … (Read More)

Derivation of Transmission Loss Formula: An accurate method of obtaining a general derivation of transmission loss formula has been given by Kron. This, however, is quite complicated. The aim of this article is to give a simpler derivation by making certain … (Read More)

Optimal Load Flow Solution: The problem of optimal real power dispatch has been treated in the earlier section using the approximate loss formula. This section presents the more general problem of real and reactive power flow so as to minimize the … (Read More)

Optimal Scheduling of Hydrothermal Processes: The earlier sections have dealt with the problem of optimal scheduling of a power system with thermal plants only. Optimal operating policy in this case can be completely determined at any instant without reference to operation … (Read More)
