Load Flow Calculation

The introduction of distributed generation (DG) into distribution network will greatly impact on its operation and security inevitably, load flow calculation with distributed generations is the basic premise for the optimization planning and operation of distribution network, so the power flow in distribution network containing DG should be calculated .This paper analyzes several common DG in the former back flow calculation and mathematical model, with the first generation method fail to deal with PV node problem, improves back/forward substitution method based on node-layer, the branch search method is presented to form node impedance matrix to modify the PV node reactive injection. so that it can effectively deal with PV nodes, and the program written by matlab7.1, several schemes are designed for the different modes of DGS and are tested in IEEE33 node system and verifies the feasibility of the method, the reliability of the program.

Raphson Method

This thesis implements power flow application, Newton-Raphson method. The Newton-Raphson method is mainly employed in the solution of power flow problems. The network of Myanma electric power system is used as the reference case. The system network contains 90 buses and 106 brunches. The weak points are found in the network by using Newton-Raphson method. Bus 16, 17, 85 and 86 have the most weak bus voltages. The medium transmission line between bus 87 and bus 17 is compensated by using MATLAB program software. The transmission line is compensated with shunt reactors, series and shunt capacitors to improve transient and steady-state stability, more economical loading, and minimum voltage dip on load buses and to supply the requisite reactive power to maintain the receiving end voltage at a satisfactory level. The system performance is tested under steady-state condition. This paper investigates and improves the steady–state operation of Myanma Power System Network.
