Economic power dispatch for an interconnected power system based on reliability indices

Falah Abodahir Athab, Wafaa Saeed Majeed

Abstract


Reliability indices are always one of the most important factors in the  power systems.In this paper,the problem of the economic load dispatch(ELD) and the problem of economic emission load dispatch(CEELD) have been improved taking into account reliability indices.That is,the problem and reliability of ELD are proposed as  combined economic load dispatch reliability(CELDR) and the problem CEELD is suggested as (CEELDR).In solving CELDR and CEELDR problems,tried to use power generators in a very reliable way to save system load,as well as minimum fuel and emission costs.In this effort,the ELD of power plants is successfully implemented in a single system containing 6 generating units, taking into account the reliability and emissions of the system with and without system power loss,inequality and inequality constraints,and valve point effects using the exchange market algorithm(EMA).The results suggest that reliability indicators in ELD can be used to create greater reliability in providing consumers with uninterrupted power.
