Streszczenie:

This thesis investigates two algorithms for the steady state analysis of HVDC convertor plant. The first is an already well established frequency domain technique, known as IHA (Iterative Harmonic Analysis), and the investigation centres on the nature of the algorithm under divergent conditions. In particular, a mathematical analysis of the algorithm is used to prove that divergence of the algorithm is not necessarily indicative of a physical harmonic instability. The second algorithm is developed to exploit the IHA technique within the context of the three phase a.c.-d.c. loadflow as an alt

This thesis presents a comprehensive solution technique for power system harmonic analysis with unbalanced load flow conditions. It is based on multiphase modelling of the system in phase quantities. Two of the most important features of this technique are the multiphase approach to the harmonic load flow problem, and the capability to add component nonlinearities easily. The first feature allows the technique to be used for either single-phase or three-phase, and for either balanced or unbalanced harmonic analysis. The second feature allows the later addition of power electronic device mode

This increases the level of uncertainty witnessed within the power system as such, as the penetration of renewable energy systems continue to increase, their effects cannot be trivialised.

Quando se trata de redes isoladas, a disseminação de geração baseada em renováveis é ainda mais desafiante. A presente dissertação tem como objetivo analisar, com recur

碩士<br>義守大學<br>電機工程學系<br>89<br>Since the features of distribution systems are different from transmission systems, the solution techniques for load flow problem need to be modified. Comparing with transmission systems, distribution networks are commonly: (a) three-phase unbalanced oriented; (b) radial with sometimes weakly-meshed topology; (c) with high resistance to reactance (r/x) ratio; (d) unbalanced distributed load; (e) extremely large number of branches/nodes. Those features make the traditional load flow method, such
