Abstract:

This study presents a multi-attribute decision making (MADM) framework in support of strategic resource planning of electric utilities. Study efforts have focused on four technical issues identified to be essentially important to the process of strategic resource development, i.e., decision data expansion, MADM analysis with imprecise information, MADM analysis under uncertainty and screening applications. Main contributions from this study are summarized as follows. First, an automatic learning method is introduced for decision data expansion aiming at reducing the amount of computations involved in the creation of decision database. Test results have shown that the proposed method is feasible, easy to implement, and more accurate than the techniques available in the existing literature. Second, an interval-based MADM methodology is developed, which extends the traditional utility function model with the measure of composite utility variance, accounting for individual errors from inaccurate attribute measurements and inconsistent priority judgments. This enhanced decision approach would help the decision-maker (DM) gain insight into how the imprecise data may affect the choice toward the best solution and how a range of acceptable alternatives may be identified with certain confidence. Third, an integrated MADM framework is developed for multi-attribute planning under uncertainty which combines attractive features of utility function, tradeoff/risk analysis and analytical hierarchy process and thus provides a structured decision analysis platform accommodating both probabilistic evaluation approach and risk evaluation approach. Fourth, the application of screening models is investigated in the context of integrated resource planning of electric utilities as to identify cost effective demand-side options and robust generation expansion planning schemes.

Abstract:

The thesis aims to introduce an efficient resource development strategy in electric utility long term planning under uncertainty considerations. In recent years, electric utilities have recognized the concepts of robustness, flexibility, and risk exposure, to be considered in their resource development strategy. The concept of robustness means to develop resource plans that can perform well for most, if not all futures, while flexibility is to allow inexpensive changes to be made if the future conditions deviate from the base assumptions. A risk exposure concept is used to quantify the risk hazards in planning alternatives for different kinds of future conditions. This study focuses on two technical issues identified to be important to the process of efficient resource development: decision-making analysis considering robustness and flexibility, and decision-making analysis considering risk exposure. The technique combines probabilistic methods and tradeoff analysis, thereby producing a decision set analysis concept to determine robustness that includes flexibility measures. In addition, risk impact analysis is incorporated to identify the risk exposure in planning alternatives. Contributions of the work are summarized as follows. First, an efficient resource development framework for planning under uncertainty is developed that combines features of utility function, tradeoff analysis, and the analytical hierarchy process, incorporating a performance evaluation approach. Second, the multi-attribute risk-impact analysis method is investigated to handle the risk hazards exposed in power system resource planning. Third, the penetration levels of wind and photovoltaic generation technologies into the total generation system mix, with their constraints, are determined using the decision-making model. The results from two case studies show the benefits of the proposed framework by offering the decision makers various options for lower cost, lower emission, better reliability, and higher efficiency plans.

Abstract:

Electric utilities engaging in integrated resource planning face a variety of uncertainties which complicate the development of robust plans. These uncertainties occur in variables such as demand growth, energy price, green house gas regulations, and water inflows for hydroelectric-dominated utilities, just to name a few. This study examines the current planning methods in use among (largely North American) utilities with a particular focus on the features of each method that manage or mitigate uncertainty. The two most common planning methods (portfolio-based and scenario-based planning) are analysed and their advantages, disadvantages, potential alterations, and circumstances of best application are evaluated. These findings are then applied to the case of BC Hydro, one of the largest electric utilities in Canada, with recommendations for changes to their current planning process.

Abstract:

Many electric utilities have been tapping such energy sources as wind energy or conservation for years. However, the literature shows few attempts to incorporate such non-dispatchable energy sources as decision variables into the long-range planning methodology. In this dissertation, efficient algorithms for electric utility capacity expansion planning with renewable energy are developed. The algorithms include a deterministic phase which quickly finds a near-optimal expansion plan using derating and a linearized approximation to the time-dependent availability of non-dispatchable energy sources. A probabilistic second phase needs comparatively few computer-time consuming probabilistic simulation iterations to modify this solution towards the optimal expansion plan. For the deterministic first phase, two algorithms, based on a Lagrangian Dual decomposition and a Generalized Benders Decomposition, are developed. The Lagrangian Dual formulation results in a subproblem which can be separated into single-year plantmix problems that are easily solved using a breakeven analysis. The probabilistic second phase uses a Generalized Benders Decomposition approach. A depth-first Branch and Bound algorithm is superimposed on the two-phase algorithm if conventional equipment types are only available in discrete sizes. In this context, computer time savings accrued through the application of the two-phase method are crucial. Extensive computational tests of the algorithms are reported. Among the deterministic algorithms, the one based on Lagrangian Duality proves fastest. The two-phase approach is shown to save up to 80 percent in computing time as compared to a purely probabilistic algorithm. The algorithms are applied to determine the optimal expansion plan for the Tijuana-Mexicali subsystem of the Mexican electric utility system. A strong recommendation to push conservation programs in the desert city of Mexicali I results from this implementation.

Abstract:

Recent scientific findings have generated considerable concern about the adverse effect of greenhouse gas (GHG) emissions on the world's climate in general and global warming in particular. In Canada and many other countries, this concern has led to the adoption of legal and political steps with the aim of curbing GHG emissions. The first part of this thesis describes the steps taken by Canada in this regard.
Such steps provide a strong incentive to Canadian power systems to incorporate reduction of GHG emissions in their planning process. Thus, in the second part of the thesis, a long-term supply mix planning model is developed. Since significant decrease in GHG emissions is unlikely to occur without removal of highly polluting power plants, this model allows for decommissioning these power plants.
Finally, the supply mix planning model is applied to evaluate the strategy of joint planning (as opposed to separate planning) of the power systems of Quebec and Ontario. Results obtained from the model leads to the conclusion that joint planning is preferable from the point of view of overall social and financial cost.

Abstract:

Energy efficiency stands out with its potential to address a number of challenges that today's electric utilities face, including increasing and changing electricity demand, shrinking operating capacity, and decreasing system reliability and flexibility. Being the least cost and least risky alternative, the share of energy efficiency programs in utilities' energy portfolios has been on the rise since the 1980s, and their increasing importance is expected to continue in the future. Despite holding great promise, the ability to determine and invest in only the most promising program alternatives plays a key role in the successful use of energy efficiency as a utility-wide resource. This issue becomes even more significant considering the availability of a vast number of potential energy efficiency programs, the rapidly changing business environment, and the existence of multiple stakeholders. This dissertation introduces hierarchical decision modeling as the framework for energy efficiency program planning in electric utilities. The model focuses on the assessment of emerging energy efficiency programs and proposes to bridge the gap between technology screening and cost/benefit evaluation practices. This approach is expected to identify emerging technology alternatives which have the highest potential to pass cost/benefit ratio testing procedures and contribute to the effectiveness of decision practices in energy efficiency program planning. The model also incorporates rank order analysis and sensitivity analysis for testing the robustness of results from different stakeholder perspectives and future uncertainties in an attempt to enable more informed decision-making practices. The model was applied to the case of 13 high priority emerging energy efficiency program alternatives identified in the Pacific Northwest, U.S.A. The results of this study reveal that energy savings potential is the most important program management consideration in selecting emerging energy efficiency programs. Market dissemination potential and program development and implementation potential are the second and third most important, whereas ancillary benefits potential is the least important program management consideration. The results imply that program value considerations, comprised of energy savings potential and ancillary benefits potential; and program feasibility considerations, comprised of program development and implementation potential and market dissemination potential, have almost equal impacts on assessment of emerging energy efficiency programs. Considering the overwhelming number of value-focused studies and the few feasibility-focused studies in the literature, this finding clearly shows that feasibility-focused studies are greatly understudied. The hierarchical decision model developed in this dissertation is generalizable. Thus, other utilities or power systems can adopt the research steps employed in this study as guidelines and conduct similar assessment studies on emerging energy efficiency programs of their interest.

Abstract:

Generation and transmission investment planning in deregulated markets faces new challenges particularly as deregulation has introduced more uncertainty to the planning problem. Tradi- tional planning techniques and processes cannot be applied to the deregulated planning problem as generation investments are profit driven and competitive. Transmission investments must facilitate generation access rather than servicing generation choices. The new investment plan- ning environment requires the development of new planning techniques and processes that can remain flexible as uncertainty within the system is revealed. The optimisation technique of Stochastic Dual Dynamic Programming (SDDP) has been success- fully used to optimise continuous stochastic dynamic planning problems such as hydrothermal scheduling. SDDP is extended in this thesis to optimise the stochastic, dynamic, mixed integer power system investment planning problem. The extensions to SDDP allow for optimisation of large integer variables that represent generation and transmission investment options while still utilising the computational benefits of SDDP. The thesis also details the development of a math- ematical representation of a general power system investment planning problem and applies it to a case study involving investment in New Zealand’s HVDC link. The HVDC link optimisation problem is successfully solved using the extended SDDP algorithm and the output data of the optimisation can be used to better understand risk associated with capital investment in power systems. The extended SDDP algorithm offers a new planning and optimisation technique for deregulated power systems that provides a flexible optimal solution and informs the planner about investment risk associated with uncertainty in the power system.

Abstract:

While the utilization of energy efficiency has grown in recent years, it has not been distributed evenly across the country. In some states, over 2% of a utility’s budget is spent on energy efficiency; in other states that number is 0. Much of the growth in energy efficiency has been due to state policies and the development utility-level energy efficiency programs. Yet, all utility programs are not created equal. Because they are often exempt from state regulation (and therefore state energy efficiency policy), publicly-owned utilities have traditionally lagged behind IOUs when it comes to EE programs. This research quantifies energy efficiency programs in four Midwestern states: Iowa, Indiana, Michigan and Wisconsin. The first part of the thesis evaluates 474 electric utilities as to whether they had an energy efficiency program in 2010. The second part of the thesis evaluates each utility’s EE program spending in terms of energy and utility specific factors, as well as socio-economic, housing stock and political variables. Through descriptive statistical analysis and the creation of a predictable linear regression model, this thesis identifies relationships between the dependent variable (EE program spending as a % of a utility’s total revenue) and commonly cited barriers to EE program development. Through the analysis, this study finds widespread EE program coverage in Iowa, Michigan and Wisconsin. Also, it finds states are the greatest predictor of utility energy efficiency program spending. A utility’s ownership type and the share of homes that heat with electricity are also significant predictors of program spending.

Abstract:

This report evaluates the business plan at Eskom's Matla power station by comparing it to grounded theory to establish whether the strategies selected prepare the station to be competitive in a commercialised environment. It is assumed that the key success factors in a commercialised environment would be low cost operation and service delivery to meet customer demands. It is shown that the business plan is deficient in many regards, but the strategies selected are adequate in preparing the station for operation in a commercial environment. A questionnaire is used to determine management buy-in to the strategies selected to gauge support for the strategies. Reasons for strategies not meeting all objectives are also looked at and recommendations are made to improve· the business plan and the implementation of the strategies selected. The question of whether the strategies support corporate strategy is answered by comparing the vision, mission and strategies selected by the station to the vision and mission of Eskom Holdings and Eskom Generation. The findings here were that, although long and awkward, the mission statement supports corporate mission, while the vision contradicts corporate vision. Matla's vision supports growth through diversification while Eskom Holdings and Eskom Generation focus on core business.

Abstract:

M.Com. (Business Management)
In February 1990 the State President of the Republic of South Africa unbanned the political organisations that were previously banned. This set the scene for full and free elections. It also brought new role players to the fore. Parastatal institutions, including Eskom, now faced the problem of having to adapt to the new environment. or face the possibility of serious intervention from a new Government. During 1990 Nedcor and Old Mutual formed a team of experts, including one specialist from Eskom, to seek alternative paths that South Africa may embark on in an attempt to foster an environment that would enhance the possibility of a successful transition to a democratic South Africa. The team produced a scenario, which became known as the "change of gears" scenario. One of the cornerstones of this scenario is a kick-start of the economy, inter alia through supplying with electricity those citizens who do not yet have access to electricity. With a view to this the Nedcor/Old Mutual scenario suggests an electrification rate of one million houses per annum. This figure was criticised because of the negative effect it would have on the balance ofpayments. The Nedcor/Old Mutual scenario was presented to many parties, including the Cabinet and the ANC Executive. Although criticism was expressed against this scenario, it served a meaningful purpose in that it was probably one of the impetuses for the ANC's national meeting on electrification and the creation of other scenarios, such as that of Van der Berg. as well as other studies such as this dissertation. This dissertation, comprises an environmental scan of the needs and wants of the parties affected by electricity and electrification. These parties were identified as: Eskom; the local authorities; the people who currently do not have access to electricity; the central government; the unbanned political parties; and the consumers ofelectricity. It has been ascertained that South Africa, in the form of Eskom, has an excess power generating capacity of approximately 25 percent; that 65 percent of the population does not have access to electricity; and that the price of electricity is low as compared to that ofthe rest ofthe world. It has also been established that in South Africa the percentage ofhouseholds (ii) electrified is approximately twice as high as that of any other country on the sub-continent. From this it was concluded that the issue of electrification is a political one, nevertheless an opportunity to improve the economy. The views of the interest groups were studied, with particular emphasis on the views expressed at the ANC's first national meeting on electrification. The views of the parties were reduced to a list of sixteen requirements/expectations. These were divided into two groups, these on which there are a high degree of consensus and those on which agreement would have to be obtained. The latter included the pricing issue for prepaid meter customers versus the other small power users; the effect of poor load distribution on the price paid by black local authorities; the gross underutilisation ofmanpower in the industry, due to the fragmented structures; the redistribution of wealth; strong Government intervention; and the question of the level ofprofits in the industry. From this follows the recommendation that the electricity supply industry be onsolidated under the Eskom structure and that the issue around electrification be depoliticised.It is also recommended that a stable rate of electrification of approximately 250 000 houses per annum be maintained.

Abstract:

This thesis relates to a study of abnormal conditions on a threephase distribution feeder of industry like State Electricity Commission of Victoria (SECV) with several loads and a capacitor bank. An induction generator, which plays the role of a dispersed storage and generation unit, driven by a hydraulic turbine, which is a common form of renewable energy scheme, is connected to the distribution feeder through a Δ/Y transformer. Transients caused switching of the induction generator, by single line-to-ground fault, double line-to-ground fault through contact resistances, broken conductor touching the ground through a small resistance, isolating the induction generator to form its own supply domain (islanding) etc are investigated and interesting conclusions of practical importance are derived. The IBM PC version 4 of the Electro-Magnetic-Transient Program - Alternative Transient Program (ATP), was used to solve this problem. The program also gives output results for automatic plotting in time domain. Accordingly, transient voltages at several nodes and transient currents at interesting points were plotted from the output results. Planning and operational aspects like voltage control, reliability, harmonics, earthing, and contractual matters between the private generator and the utility are also considered. Technical aspects interconnections between the private generation and the utility has been considered. Interesting conclusions, valuable for insulation co-ordination, interrupting duty on circuit breakers, effect on response of protective relays and automatic control systems are pointed out. It also considers security to personnel and protection of metering equipment. The thesis also offers guide for contractual matters between the utility and the private generation.

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.
