Solving economic load dispatch with reliability indicators

Abstract EN

Due to the great importance of reliable indicators in electrical operating systems in all its different parts, it has been considered the most important factors in the design and maintenance of the electrical system, especially during its operation.

The main reason for attention to reliability indicators relates to interruptions in the power system that are provided to consumers.

The introduction of reliable indicators to solving an economic load dispatch (ELD) issue increases the possibility of providing customers with a required load with the highest degree of reliability.

The ELD issue has been solved with reliability indicators.

This means that the ELD problem with reliability is combined into one problem called combined the economic load dispatch with reliability (CELDR).

Solving the above problem lowers the fuel cost while increasing the reliability of the generators while preparing the required load.

The exchange market algorithm (EMA), in this work, has been implemented in a system of 26 generating units to solve the CELDR issue.considering system reliability, inequality, and equality constraints.

The results obtained show the direct effect of using reliability indicators in solving the above problem, where the best results were obtained using the EMA algorithm to solve the mentioned problem, compared to other algorithms.
