POWER FLOW SOLUTION BY USING MATLAB

Performance of power systems under steady-state operation can be analyzed by studying
power flow study. Gauss-Seidel iteration method was used to solve the power flow
equations. The power flow programming was made with help ofMATLAB software. The
voltages, currents, and real and reactive power flows in the power system under a given
set of load conditions were determined as well as the line current, line flows and line
losses. With all information available, the user of power flow study can determine
whether any of the components in a power system will be overloaded by the particular
conditions of the study. If the ratings of any components are exceeded, then the
conditions of this study are an unacceptable steady state operating condition and
something else must be tried. With load studies, the engineers are able to plan ahead the
operation of the power system under normal conditions by fulfilling the economic and
security requirements.
