Evaluating power trading in selected countries of the Southern African development communityLukamba Muhiya, Jean-Marc January 2008 (has links)
Thesis (DTech (Public Management))--Cape Peninsula University of Technology, 2008 / The research explores an evaluation of cross-border electricity trading among
countries of the Southern African Development Community (SADC).
Understanding this trading achieve through an analysis of various global electricity
markets. The research disclose that in the electricity markets in Europe, North
America, South America and Asia analysed in this thesis, none managed to
successful eliminate power shortages. Their situation, however, is different from
that of the Southern Africa Power Pool (SAPP). The apparent poor design of the
SAPP as a regional power pool impacts negatively on power trading within its
region.
A strategic public management model was used to analyse the organisational
dynamics of the electricity companies of the three countries selected for this
research (Democratic Republic of Congo, South Africa and Zimbabwe). A
Strength Weakness Opportunities and Threats (SWOT) analysis carried out on
these markets indicated that there are problems among different electricity
companies, each requiring a solution. Each country's evaluation highlighted a
need for an accountable government to implement a goal-directed policy to militate
against any dysfunctional operations by the electricity companies.
The quantitative and qualitative data analyses of the fieldwork results showed the
SAPP had struggled hard to increase the capacity of members' power trading.
The study indicated internal problems in terms of increasing trading volumes. The
time series analysis showed power trading in the short-term electricity market had
decreased annually. Linear regression analysis also indicated a decline in the
capacity of the SAPP. A number of factors could explain the reduction of capacity
in the SAPP, but the research results suggested a strong probability that electricity
capacity would decrease further, as the countries, trading in the power pool have
experienced decreased electricity volume annually because of internal demand.
In addition to a number of. recommendations, the research proposes a normative
model that could be used by nations to manage and assess the electricity market.
An understanding of the input as adapted from Easton inpuUoutput normative
11
transformational systems model, in terms of different governments, should assist
policy-makers to transform the power trading generating distribution industry.
Global experience shows the need to establish a normative transformation of the
electricity industry in the SADC region. It is clear from the results of this study
that the SADC electricity markets have been poorly transformed in terms of a
particular normative guideline.
The situation has also disadvantaged the SAPP, which, in recent times, had less
electricity capacity with which to trade. Implementation of the normative model in
the context of this study sought to analyse all aspects that might influence the
transformation of the electricity sector, and to grow a currently dysfunctional state
to that of functionality and reliability. While each country faced its own reality in
terms of the transformation of its public enterprises, the study recommends the
normative model be implemented in the same way in each selected country.

The Development of a Composite Transmission Electrical Network Utilisation Comparative Study IndexAuditore, Frank Anthony 12 1900 (has links)
Thesis (PhD)--University of Stellenbosch, 2004. / 242 Leaves printed single pages, preliminary pages i-viii and numberd pages. Includes bibliography. Tables and figures. / ENGLISH ABSTRACT:The aim of the proposed study was to develop an electrical utility organisational
performance measure indicator that measures electrical network utilisation (U)
for the actual maximum demand and total energy transferred. The scope of the
study extended itself to include reliability and exogenous considerations. The
scope of the research study included three primary variables with secondary
variables as the performance measures.
The available data was screened and filtered from outliers, and thereafter,
multivariate analysis was applied in deriving the overall linear equation for each
of the above primary variables. The statistical process included the application
of principal component analysis and factor analysis, a comparison between the
two, and the derivation of linear equations. The study produced linear equations
relating to the former.
The primary variables were presented in the form of a 3-Dimensional scatter
plot. Each variable was inspected for linearity and clustering to validate the
results and include any previously excluded outliers that complied with linear
functionality. A practical application of the research findings was included. This
included the extremes of linearity and clustering. The research concludes with
further research opportunities in this study direction. / AFRIKAANSE OPSOMMING:Die doel van hierdie ondersoek was om 'n maatstaf te ontwikkel wat
elektrisiteitsverskaffers in staat stel om die effektiwiteit en benutting van die
elektriese transmissienetwerk te meet. Dit sluit die maksimum aanvraag en totale
hoeveelheid energie wat deur die transmissienetwerk oorgedra word in. Die
omvang van die studie is uitgebrei om ook eksterne faktore en
betroubaarheidsoorwegings in te sluit.
Die beskikbare inligting is gekeur en gefilter om uitskieters uit te skakel en daarna
is multivariate analise gebruik om 'n lineêre vergelyking vir elk van die primêre
veranderlikes te ontwikkel. Die statistiese analise het onder andere van
hoofkomponente analise en faktor analise gebruik gemaak. 'n Vergelyking tussen
die twee metodes is gemaak en liniêre vergelykings is afgelei.
Die primere veranderlikes was gesamelik getoon in n’ 3-dimensionele grafik. Die
lineariteit en groepering van elke veranderlike is egter ondersoek om die resultate
te staaf en enige uitskieters wat voorheen uitgesluit is maar wel aan die lineêre
verband voldoen het in te sluit. 'n Praktiese toepassing van die bevindings was
uitgevoer en het die uiterstes van lineariteit en groepering ingesluit. Die
ondersoek word afgesluit met 'n bespreking van moontlike verdere
navorsingsgeleenthede.
