Traditionally electrical power industry has been regulated and monopolized. However, since 1980s it has undergone a period of restructuring throughout the world. This privatization procedure has made the planning and operation of the generation, transmission and distribution parts of power system relatively more independent and disconnected. The transmission system planners lost their direct control over plant investments. As a result, planning of the transmission system became more complex than it ever was. This created a need for mechanisms to assess the economics and reliability of transmission expansion planning. This thesis presents a methodology to determine the maximum amount of new generation that can safely be connected from a region to the transmission system. Two new indices are developed to monitor impact of additional generation in a specific region. The first index examines the effect of additional generation to the transmission system as a whole by taking into account the overloading amount and possibility of each line in the region. The second index identifies the weak points in that region that needs to be strengthened by evaluating the impact of the additional generation on each line separately. The proposed methodology was applied to Turkish Transmission Network model of 2026 considering four different case studies. These are peak demand and minimum loading scenarios where high and low wind energy investments are considered separately.

On the parametric and nonparametric prediction methods for electricity load forecasting Erişen, Esra; İyigün, Cem; Department of Industrial Engineering (2013) Accurate electricity load forecasting is of great importance in deregulated electricity markets. Market participants can reap significant financial benefits by improving their electricity load forecasts. Electricity load exhibits a complex time series structure with nonlinear relationships between the variables. Hence, new models with higher capabilities to capture such nonlinear relationships need to be developed and tested. In this thesis, we present a parametric and a nonparametric method for short-term ...
Short term electricity price forecasting in Turkish electricity market Özgüner, Erdem; Güven, Ali Nezih; Tör, O. Bülent; Department of Electrical and Electronics Engineering (2012) With the aim for higher economical efficiency, considerable and radical changes have occurred in the worldwide electricity sector since the beginning of 1980s. By that time, the electricity sector has been controlled by the state-owned vertically integrated monopolies which manage and control all generation, transmission, distribution and retail activities and the consumers buy electricity with a price set by these monopolies in that system. After the liberalization and restructuring of the electricity powe...
Demand, supply and partial equilibrium analysis of electricity energy pricing for Turkish market Özdemir, Asena; Kestel, Sevtap Ayşe; Department of Actuarial Sciences (2013) Electricity energy is a fundamental commodity for all sectors of the economy. For this reason, estimating the factors and their impacts on electricity consumption and production are important to maintain sustainability in electricity energy market. The aim of the study is to determine the association between main macroeconomic and sectorial indicators with electricity consumption and production. For estimating electricity demand, annual electricity consumption, Gross Domestic Product (GDP), electricity tran...
The impact of photovoltaic power plant penetration level on security constrained unit commitment and an approach for reducing curtailment of PV energy Kahraman, Özgür; Ünver, Baki Zafer; Department of Electrical and Electronics Engineering (2016) As a main rule of electricity grid, the balance of generation and demand must be maintained. The system operators execute “Unit Commitment (UC)” process in day-ahead market in order to fulfill this aim. The Security Constrained Unit Commitment (SCUC) algorithm creates optimal hourly schedules for generators with minimum total electricity generation cost considering the forecasted hourly demands for the next day and the generation offers while satisfying the constraints of generators and transmission system....
Performance based ratemaking in electric distribution services Uğuz, Mustafa; Sevaioğlu, Osman; Department of Electrical and Electronics Engineering (2006) Regulation is one of the main elements in electric distribution services. The objective of the regulation is to maintain the balance between the rates and the service quality of electric distribution on behalf of both utilities and customers. In rapidly changing world the regulation regimes are also changing .In this thesis, an increasingly implemented regulation model in electric distribution, performance based ratemaking is studied. Its advantages and disadvantages, implementing methods and its quality ef...
