]]> power quality. Nowadays, interest in power quality has increased since it has become a very
important issue in power system delivery. One of the major problems of ensuring a certain level of
power quality are harmonics. The aim of this project is to investigate an impact of photovoltaic
(PV) on harmonic voltage distortion (HD) in real MV distribution network. Different scenarios will
be implemented where solar power plant is going to be modelled with high variability of load and
generation to see their effects on the systems power quality (PQ). Those scenarios are when PV is
disconnected from the grid and PVs are connected with 2 different powers. Results presented below
showed that PV improves power quality of the system, because their inverters are source of
harmonics and they increase HD. However, that impact is not very significant and harmonic limits
are not violated. A load flow analysis is done for the model of test system 110/35/10kV in which a
distributed generator is added, that is on-grid or off-grid. The network modelling and simulation is
done in DIgSILENT PowerFactory software.]]> success factors in the context of information systems (IS) projects. Through the process of review of
88 books, relevant studies and scientific works 72 success factors were detected, with a total of 689
appearances, which are then classified into six factor groups: Planning, Project team, Project
management, Development, Customer, Project facilitation. The paper reveals that factors that were
recognized as the most critical ones for the success of information systems projects by majority of
authors belong first to Planning, and then to Project team and Project management groups of factors.
Findings in this paper are expected to serve as a valuable theoretical basis for future empirical
research of success and failure of projects in modern information technologies (IT) organizations,
and development of related IS project success models.]]>
