Here at http://powerflowcalculation.blogspot.co.uk, you'll find the blog for our year 2 project blog titled "Optimisation Technique for Power Flow Calculation", by Chengbin Hou and Khamil Mumuney (Group 23), supervised by Prof QH Wu.
The ultimate purpose of our project is to provide a more advanced technique for the power flow calculation as well as the optimal power flow (OPF) calculation. The motivation of doing research in this field comes from the immediate benefits in sustainable development (e.g. improve the efficiency in power dispatch). However, at the present stage, the main objective is to be able to work out some significant parameters (i.e. voltage magnitude, phase angle, real power and reactive power) in a given power system under the normal AC steady-state operation.
Up to now, we have been able to:
1.) distinguish the bus type, draw a one-line diagram, change quantities in per unit basis and construct the bus admittance matrix;
2.) deduce the basic power flow equations in theory;
3.) develop a flowchart and thus, design a pseudo code (algorithm) to solve power flow problem based on Gauss-Seidel method;
4.) apply Gauss-Seidel method to solve a simple power system by hand, using the algorithm and the equations we formulated;
5.) employ the MATPOWER (a MATLAB package) to perform power flow calculation on the IEEE 14-bus testing system.
