Electricity market model of the Czech Republic
Kubát, Jan ; Pelikán, Jan (advisor) ; Kodera, Jan (referee) ; Marvan, Miroslav (referee)
A competitive electricity market has been established in many European countries including the Czech Republic. The electricity market includes a limited number of significant producers and traders, which can be described by oligopoly model. Since the electricity transmission and distribution are regulated, I consider two types of players performing in the electricity market: producers of electricity and traders, who buy electricity from producers and sell it to final customers. I derive oligopoly model with producers and traders "a la Cournot" and calculate a formula of equilibrium strategies. I use these theoretical findings to build a dynamic oligopoly model Ele. Ele is formulated as a mixed complementary problem and calibrated on data for the Czech Republic and neighbor states for several scenarios. The model was specified and calculated in GAMS software by the PATH solver. The results represent a Nash equilibrium. That means for individual producers: electricity generation, investment in new power plants construction and emission permits purchases. For traders the results are: equilibrium purchases, sales and cross-border transfers of electricity in each particular time period. Ele derives also equilibrium regional wholesale and retail electricity prices, emission permit prices and prices of cross-border auctions. Ele results point to an economic profitability of new nuclear power plants constructions. Further, I formulate a game in short-term electricity market, where I advise to Czech market participants, subjects of settlement, how much and in which circumstances to buy or sell electricity. Equilibrium results obtained through simulations based on the principle of a fictive game show that the current payment system of imbalance in the Czech Republic does not increase the risk of instability of electricity networks.

Aspects of Czech energy market liberalization in the context of European Union
Bačová, Michaela ; Němcová, Ingeborg (advisor) ; Horák, Jiří (referee)
This bachelor thesis takes a comprehensive overview of the electricity market liberalization emphasizing the impact on households. Despite efforts to create a common energy market, competitive environment is significantly influenced by the presence of natural monopolies in the transmission and distribution sector. Possibility to switch electricity supplier may lead to price savings, but due to high proportion of regulated components in total price of electricity, liberalization itselfs creates only little space for lower price. Electricity price is influenced by many factors, but strong interdependence of Central European region enhances the risk of being influenced by higher prices. This thesis divides electricity market into individual subjects with regard to the proportion on total electricity price for end user.

Electricity market and its regulation
ŘÍHA, Jaroslav
The objective of the Bachelor Thesis is a survey of electricity market and its regulation in the Czech Republic. The fundamental principles of regulation of the electricity market are determined primarily by Act No. 458/2000 Coll., on the Conditions of Business and State Administration in the Energy Industries and Changes to Certain Laws (the Energy Act) as amended. The most significant purpose of the electricity market is price determination based on demand and supply. Also the Energy Regulatory Office contributes to competition within the energy market. The total consumer price consists of several partial amounts: commodity price, transportation price, distribution and contribution for renewable resources. Only the commodity price is not object of regulation. The Bachelor Thesis includes also comparison of two different methods of regulation of the distribution price ? revenue-cap and price-cap.

IS for electricity market domain
Blaha, Jan ; Pour, Jan (advisor) ; Derfler, Václav (referee)
There are many companies operating in the current electricity market and new companies are still forming. This gives every consumer an option to choose a company selling electricity. Electricity dealers can even buy or sell electricity from abroad. Although this situation seems to be natural, it's very complicated to achieve. It's necessary to follow a lot of rules and business processes to be able to establish a functional liberalized market. Because of the amount of business processes it's obvious that liberalized market depends first of all on information systems. However, to develop an information system is usually big investment and it is necessary to find some way to cut the information systems prices. This thesis introduces an effective way of system development for the electricity market domain. This method is introduced as Model Driven Development (MDD) methodology. The idea promoted by MDD is to use models to describe programs and automation code generators to transform models into source code. Model creation is obviously much faster than writing source code, which makes software development more effective. In the category of supporting MDD tools, Damas Energy platform is introduced. The main goal of this thesis is to analyze the usability of Damas Energy with MDD and to show which method to choose when developing information systems for the electricity market domain.

Nuclear energy and its future
Eretová, Kamila ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
This work deals with the potential of nuclear energy in general and in our country. Nuclear energy offers as almost a necessary alternative to fill growing demand for electricity in our country and the world. Increased attention is paid to the electricity market in our country, the role of nuclear energy in the Czech energy mix and the possibilities of its use in the future as an alternative to other energy sources (renewable, fossil resources), and savings and imports from abroad. The author summarizes the main benefits, but also the risk that nuclear energy brings. Does not forget the attitude of environmentalists, opponents and the public to the nuclear issue, which improves long-term, giving scope for the use of nuclear energy.

Electricity Market in the Czech Republic, its definition
Kloubec, Milan ; Koudelka, Jan (advisor) ; Sůva, Jaroslav (referee)
This bachelor thesis deals with the characterization of the Electricity Market in the Czech Republic and its definition. The main part of the thesis is systematically divided into three chapters, where the first chapter addresses the theoretic framework of market definition and marketing distinctiveness in the Electrical Power Engineering Industry. The second chapter approaches the practical part of the thesis wherein the theory of market definition is applied to the Electricity Market in the Czech Republic. In the process, an in-depth definition of individual market participants, as well as of individual types of electricity deals, is -- among many others -- carried out as well. The third chapter focuses on the definition of the market product, i.e. electricity, and its marketing specifics.

Trh s elektřinou v České Republice (teorie a praxe)
Pavlátka, Pavel ; Schwarz, Jiří (advisor) ; Brychta, Pavel (referee)
Liberalization and privatization of the electricity industry is one of the most important processes in the few last years. Even when the electricity market is fully open, substantial barriers to competition often remain. These barriers are refusal of access to the market, the lack of capacity in interconnectors and long-term contracts. The process of liberalization has shown that a third-party access to the network is a critical and important factor in ensuring a real and effective liberalization of the market. The process of liberalization has also supported new ways and forms of energy trading including financial contracts instead of purely physical contracts for the delivery of electricity. It is a question if the benefits of liberalization of the electricity industry compared with a regulated private monopoly or public monopoly were profitable. Someone could argue that the liberalization of electricity tends to bring benefit to monopoly structures and increase prices of electricity in industry. This work tries to present the pros and cons of liberalization in the electricity industry while taking in consideration the best means of making the liberatization as much profitable and useful as possible.
