Alternative models for markets with nonconvexities
Fuller, J. David; Çelebi, Emre (Elsevier Science Bv, 2017)In many electricity markets, the market operator solves a social welfare maximization (SW) model to determine market prices and generation (and consumption) "dispatch" instructions to firms participating in the market. ... -
Co-optimization models of generation and transmission investments with market-clearing equilibrium
Uyan, Zeki (Kadir Has Üniversitesi, 2018)Methods for co-optimizing transmission and generation investments including bi-level or multi-level problems consider trade-offs with market operations and interactions in electric power supply and demand. Under fairly ... -
A Comparative Study of Energy Models for Turkish Electricity Market Using LEAP
Massaga, Daniel Julius; Kirkil, Gökhan; Çelebi, Emre (IEEE Computer Society, 2019)Fossil fuel thermal power plants constitute a large part of the Turkish electricity generation capacity. Turkish government has been developing several energy policy documents to evaluate how various renewable energy sources ... -
Determination of time-of-use prices in electricity markets using clustering analyses
Hussain, Mohsan (Kadir Has Üniversitesi, 2016)in this thesis a clustering analysis to determine the blocks (clusters) of hours for time-of-use (TOU) pricing scheme is proposed and different clustering algorithms are compared using different measures i.e. change in ... -
Electricity market equilibrium models with dynamic demand functions
Çelebi, Emre (2013)Many electricity market models have either mostly ignored the demand response to changing prices (e.g. day-ahead models with mostly fixed demand) or at the other extreme they assumed that the full demand response occurred ... -
Gamma-Robust electricity market equilibrium models with transmission and generation investments
Çelebi, Emre; Krebs, Vanessa; Schmidt, Martin (SPRINGER HEIDELBERG, 2021-03)We consider uncertain robust electricity market equilibrium problems including transmission and generation investments. Electricity market equilibrium modeling has a long tradition but is, in most of the cases, applied in ... -
Generation/transmission investment planning integrated with market equilibrium models in electricity markets
Çelebi, Emre (IEEE Computer Society, 2017)This paper introduces integrated models for transmission investments anticipating the generation investments and market-clearing equilibrium. Market-clearing models for deregulated electricity markets can inform decision ... -
Market price simulations for Turkish electricity market using equilibrium models
Çakır, Hande (Kadir Has Üniversitesi, 2014)Electrical energy which is known as secondary energy sources is generated by the conversion of renewable energy sources to potential and chemical energy or is generated by variety processes of fossil fuels. Electricity is ... -
Market-clearing simulations and analyses for Turkish electicity market market
Şentürk Eker, Cansu (Kadir Has Üniversitesi, 2017)in this thesis current market structure of the Turkish electricity market which uses a uniform pricing system is analyzed and new market-clearing mechanisms (e.g. single or nodal pricing) are investigated for the market ... -
Master problem approximations in Dantzig-Wolfe decomposition of variational inequality problems with applications to two energy market models
Çelebi, Emre; Fuller, David J. (Pergamon-Elsevier Science Ltd, 2013)In this paper a modification to Dantzig-Wolfe (DW) decomposition algorithm for variational inequality (VI) problems is considered to alleviate the computational burden and to facilitate model management and maintenance. ... -
Models for long-term electricity price forecasting for Turkish electricity market
Özçelik, Sirun (Kadir Has Üniversitesi, 2017)in this study we have developed models for long-term electricity price forecasts for Turkish electricity market using multiple regression and time series forecasting methods. For the regression models we have firstly ... -
Reformulations of a Bilevel Model for Detection of Tacit Collusion in Deregulated Electricity Markets
Çelebi, Emre; Şahin, Güvenç; Esmaeili Aliabadi, Danial (IEEE Computer Society, 2019)In this study, we consider a collusion model for competitive pool based electricity markets operated by an independent system operator (ISO), where it aims to prevent tacit collusion among generators. In order to determine ... -
A 'Regional Energy Hub' for achieving a low-carbon energy transition
Güler, Burak; Çelebi, Emre; Nathwani, Jatin (Elsevier Sci Ltd, 2018)The transition to a low-carbon energy economy will remain a cornerstone of national energy policies of countries committed to the climate change accord for decades to come. We think that transmission investment is one key ... -
Risk constrained self-scheduling for a power producer using power to hydrogen storage in day-ahead markets
Nur Küçük, Nida (Kadir Has Üniversitesi, 2019)In this thesis, optimal weekly self-schedule of a natural gas power plant with a hydrogen storage system is determined by using a stochastic model with risk constraints in a day-ahead electricity market. Different electricity ... -
Turkey - Romania subsea transmission cable investment: Time for reconsideration?
Transmission investment is important for integrating electricity markets operated by different countries/transmission system operators (TSOs). Turkey and Romania have proposed a transmission cable linking the transmission ... -
Turkish public preferences for energy
Ediger, Volkan S.; Kirkil, Gökhan; Çelebi, Emre; Ucal, Meltem Şengün; Kentmen-Cin, Çiğdem (Elsevier Science, 2018)Public concern over energy supplies prices sustainability and efficiency has emerged as a major issue around the world. Yet most of what we know regarding public opinion on energy comes from North America and Europe. This ... -
Türkiye Elektrik Piyasası İçin Ekonomik Denge Modelleri: Piyasa Denge Modelleri İle Üretim/İletim Yatırım Modellerinin Bütünleştirilmesi
Uyan, Zeki; Eker, Cansu Şentürk; Çelebi, Emre (2018)Dünya ve Türkiye elektrik piyasalarındaki yeniden yapılanma (ve de serbestleşme) sürecinde, tekelci ve dikey yapıdaki kamu elektrik şirketi yerini özel üretim/dağıtım şirketleri ile düzenleyici ve denetleyici üst kurumların ...
