This thesis sets forth a computational framework of probabilistic loadflow analysis taking into consideration of high penetration of variableenergy resources, such as the wind generation. The framework enablesa faster and more precise estimation of the impact of variable energyresources in load flow analysis.This thesis consists of six chapters: introduction, probabilistic load flowalgorithms, computer program for PLF calculations, conclusion andfuture work, appendices and reference.The second part contains the mathematical development of theframework based on Sequence Operation Theory newly established.The formulation is novel in that it provides an improved computationalalternative to the existing simulation based frameworks.The third part contains information about program written in Fortran90/95 environment like format of reading data etc. Include the studiesbased on the standard IEEE 9-bus system. Data obtained as a resultof program’s work in debugging process are compared with manualcalculations for the same network to check if the program is workingin proper way. Moreover comprise the results obtained in the programfor largest tested network 96-RTS (24 buses).Appendices include content of two input files (random generation,system configuration for 96-RTS) and intermediate result calculated forthe 24-bus system.
