energy system, unit commitment, system reliability, wholesale electricity and capacity marketAbstract
The study aims to analyze unit commitment models and mechanisms within the wholesale electricity and capacity market in Russia and other countries, considering the methodology and criteria for assessing system reliability. The object of the study is the wholesale electricity and capacity markets in Russia, the United Kingdom, the European Union, Australia, and the United States of America. The main principles that govern the electricity markets and regulatory mechanisms within the unit commitment optimization problem are examined and the regulatory framework is analyzed. The main areas for the wholesale electricity and capacity market development with regard to unit commitment are outlined, highlighting the strengths and weaknesses of the regulatory framework that influence this process.
