1. Introduction
.
Optimal Power flow(OPF) is allocating loads to plants for minimum cost while meeting
the network constraints. It is formulated as an optimization problem of minimizing the
total fuel cost of all committed plant while meeting the network(power flow ) constraints.
The variants of the problems are numerous which model the objective and the constraints
in different ways.
The basic OPF problem can described mathematically as a minimization of problem of
Minimizing the total fuel cost of all committed plants subject to the constraints.
F( P
i
) is the fuel cost equation of the ‘i’th plant. It is the variation of fuel cost ($ or Rs)
with generated power (MW).Normally it is expressed as continuous quadratic equation.
The total generation should meet the total demand and transmission loss. The
transmission loss can be determined from power flow.
