In this study, we develop approaches for the market clearing problem in European day-ahead electricity markets. We first present the surplus maximization problem and extend it with pricing constraints that limit market loss or missed surplus associated with paradoxically accepted and rejected bids. We develop a Benders decomposition algorithm with price-based Benders infeasibility cuts to solve the problem. Our algorithm outperforms the state-of-the-art Benders decomposition algorithms and the primal-dual approach on practical-sized market instances. Then, we develop a multi-objective formulation of the problem with market surplus, market loss and market missed surplus objectives where the first one is to be maximized, and the last two are to be minimized. We develop a cone-based search algorithm to solve three-objective mixed-integer linear programming problems where at least one objective takes discrete values, and apply the algorithm on the three-objective day-ahead electricity market clearing problem. We examine the characteristics of the nondominated set of the problem and derive insights for market operators related to the design of the market rules.

Extensions for Benders cuts and new valid inequalities for solving the European day-ahead electricity market clearing problem efficiently
Ceyhan, Gökhan; Köksalan, Mustafa Murat; Lokman, Banu (2022-07-16)
© 2021 Elsevier B.V.We study the day-ahead electricity market clearing problem under the prevailing market design in the European electricity markets. We revisit the Benders decomposition algorithm that has been used to solve this problem. We develop new valid inequalities that substantially improve the performance of the algorithm. We generate instances that mimic the characteristics of past bids of the Turkish day-ahead electricity market and conduct experiments. We use two leading mixed-integer programmi...
A novel methodology for medıum and long-term electricity market modeling
İlseven, Engin; Göl, Murat; Department of Electrical and Electronics Engineering (2020-11-15)
In the electricity market, there is a considerable degree of uncertainty in electricity demand, supply, and price due to the uncertainty in parameters such as economic growth, weather conditions, fuel prices, and timing of new investments, etc. These factors in return affect the predictability of the electricity market. This thesis aims to increase the predictability and observability of the electricity market by means of a suitable and validated electricity market modeling methodology designed for medium a...
An integrated day-ahead market clearing model: Incorporating paradoxically rejected/accepted orders and a case study
YORUKOGLU, Sinan; Avşar, Zeynep Müge; Kat, Bora (2018-10-01)
In the electricity day-ahead markets (DAMs), market participants place their orders in the form of desired/accepted price levels for the submitted quantities. The market operator evaluates these orders and announces the clearing quantities and market clearing prices (MCPs) within an hour. In this paper, a mathematical model is proposed for the exact solution of clearing electricity DAM with a focus on the current Turkish system. The model is a non-linear programming (NLP) problem that maximizes total social...
Measuring the efficiency of the turkish electric distribution sector using stochastic frontier analysis
Çelen, Aydın; İyigün, Cem; Department of Industrial Engineering (2011)
This study analyzes the technical efficiencies of Turkish electricity distribution companies (21 in total) throughout 2002 and 2009. For this aim, we used six different model specifications, all of which are generated from two different Stochastic Frontier Analysis (SFA) models (Battese ve Coelli (1992&1995)). At the end of the estimations of the models, it has been seen that the signs and significance levels of the coefficient estimations are very consistent and satisfactory in all models. We also observed...
Day ahead markets
Kütaruk, Kaan; Sevaioğlu, Osman; Department of Electrical and Electronics Engineering (2013)
Day Ahead Market is a mechanism in electricity markets for adjusting the supply-demand energy and capacity balance by providing bids one day before the clearing. Market operator needs to know the available energy and capacity for reaching minimal-cost supply-demand balance one day earlier than the market has been cleared. Minimizing cost of the electricity and capacity during 24 hours of a day requires accurate information concerning the available electricity and capacity. Day-ahead marketing activity is pe...
