dc.description Objective is to discover new methods that overcome the Jacobian singularity, develop programs that perform the new methods, and finally test these programs on some well known testing systems such as IEEE-14-Bus testing system. en_US
dc.description.abstract Load flow Analysis is probably one of the most important studies of the performed on a power system since it evaluates steady state operating conditions of the system. Principal information obtained from a load flow is the voltage angle and magnitude at each bus hence the flow of active and reactive power in each line. Load flow analysis is required by other power system studies such as transient stability, contingency analysis and voltage stability. Numerical analysis is the main tool used to solve the load flow problem to obtain the desired results. A problem that faces the numerical methods is that they do not converge near the voltage stability limit, this lead to the emergence of what‟s known as Continuation Power Flow, which is a method that performs load flow beyond the voltage stability limit. A numerical technique is employed to achieve this task. Continuation Power Flow employs arrives at the full PV curve which is vital to the voltage stability analysis. Project scope is to discover and implement new methods and techniques of load flow that overcome the problem of Jacobian singularity and arrive at the full continuation curve. New methods were discovered; their mathematical expressions were derived and programmed by MATLABTM. For the sake verification, the programs were tested on IEEE -14-bus test system and results were compared with other results obtained by PSAT, Power System Analysis Toolbox used on MATLABTM and they were satisfactory. en_US
