Optimal Load Flow Solution

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 instantaneous operating costs. It is a static optimization problem with a scalar objective function …

Optimum Generation Scheduling

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 fit. If the transmission losses are neglected, the total system load can be optimally …

Reliability Considerations

Reliability Calculation: With the increasing dependence of industry, agriculture and day-to-day household comfort upon the continuity of electric supply, the Reliability Calculation of power systems has assumed great importance. Every electric utility is normally under obligation to provide to its consumers a certain degree of continuity and quality of service (e.g. voltage.and frequency in a …

Optimal Unit Commitment

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). This problem is of importance for thermal plants as for other types of generation such …

Introduction to Optimal System Operation

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 and usually a compromise has to be made for optimal system operation. Here we …
