Outlines Introduction ELD by considering Transmission line loss 2
➢ The main objective of this section is to introduces techniques of power system optimization.
INTRODUCTION • Consider N - numbers of thermal-generating units connected to a single bus-bar serving a received electrical load. • The input to each units is Fi, which represents the cost rate of the unit and • the output of each unit is pi, which is the electrical power generated by particular unit. • The total cost rate of this system is, the sum of the costs of each of the individual units
