Abstract:

The Turkish TSO (TEIAS) has been leading a project that aims the synchronous interconnected operation of the Turkish Power System and the ENTSO-E CESA (former UCTE) System. For this purpose, this study concentrates on the specific problems related to the electromechanical systems of large size hydroelectric power plants regarding low frequency inter area oscillations, which are prone to occur once the interconnected operation is established. The expected frequency of inter area oscillations after interconnected operation is close to 0.15 Hz, which is in the frequency range of the speed governi

Abstract:

Through integrated modeling of power system operations and market risks, this thesis addresses a variety of important issues on market signals modeling, generation capacity scheduling, and electricity forward trading. The first part of the thesis addresses a central problem of transmission investment which is to model market signals for transmission adequacy. The proposed system simulation framework, combined with the stochastic price model, provides a powerful tool for capturing the characteristics of market prices dynamics and evaluating transmission investment. We advocate the use of an

Abstract:

Wind generation has emerged as an important renewable resource for power systems in recent years. However, the stochastic availability and variability of wind make scheduled generation dispatch complex. Therefore, a Coordinated Hydro and Wind Generation (CHWG) strategy is proposed to improve scheduled dispatch and thereby contribute to preservation of system stability, while offering access to wind energy at grid level. The CHWG is described in detail and a feasibility study has been conducted. In CHWG strategy, the hydroelectric generation is proposed for energy reserve and compensation in th

The integration of variable renewable energy sources (VRE) is likely to cause fundamental and structural changes to the operation of future power systems.

Wind generation, with near-zero marginal costs, limited predictability, and a limited ability to provide upward dispatch, displaces price-setting thermal power plants, with higher marginal costs, changing flexibility and reserve requirem

The simple gas turbine engine Operates on the basic Joule-Brayton cycle and it is notorious for its poor thermal efficiency. Several modifications have been made to the simple cycle in order to increase its thermal efficiency but, within the thermal and mechanical stress constrains, the efficiency still ranges between 28 and 35%. However, higher values of energy utilisation efficiency have been claimed in recent years by using low grade heat from the engine exhaust either for district heating or for raising low pressure steam for chemical processes.

Energy is increasingly becoming more important in today&rsquo<br>s world. Ascending of energy consumption due to development of technology and dense population of earth causes greenhouse effect. One of the most valuable energy sources is hydro energy. Because of limited energy sources and excessive energy usage, cost of energy is rising. There are many ways to generate electricity. Among the electricity generation units, hydroelectric power plants are very important, since they are renewable energy sources and they have no fuel cost.

Abstract:

A função básica de um sistema de energia elétrica é fornecer aos seus clientes energia elétrica economicamente e tão confiável quanto possível. A importância da confiabilidade dos sistemas de energia elétrica é claramente notada quando as pessoas são confrontadas com a perda de energia elétrica, não importando se a perda provoca parada das linhas de produção ou mesmo impactos financeiros às empresas, o que pode consequentemente causar enorme impacto econômico além de situações que impactam o conforto da população. Dentro deste contexto esta tese apresenta uma metodologia para avaliação da conf

Abstract:

The current model for electricity generation is based on power plants connected to the transmission network. This provides electricity to the distribution network and after that to the consumers. To ensure the security of the electrical network and prevent a blackout, the performance of every electricity generation unit connected to the network is quantified in grid codes. In the case of the French transmission system, the requirements regarding the performance are written in a document produced by the French Transmission System Operator (TSO).

Em março de 2004, o governo brasileiro aprovou as leis 10.847 e 10.848, que alteram as bases da regulação do Setor Elétrico Brasileiro. As leis instituíram novas regras para a outorga de concessões para aproveitamentos hidrelétricos e para comercialização de energia entre agentes de geração, distribuidores e comercializadores de energia elétrica. Diante da contínua demanda por investimentos na expansão da capacidade de geração, este trabalho foi desenvolvido com o objetivo de inferir sobre a capacidade do modelo institucional vigente de atrair capital privado para investimentos em geração de e

Em um cenário de crescente demanda por energia elétrica e em face da possibilidade de crise energética, tem aumentado o incentivo à exploração dos potenciais hidráulicos por meio de Pequenas Centrais Hidrelétricas (PCHs), por representar uma fonte renovável e alternativa de geração elétrica. A construção e operação dos empreendimentos hidrelétricos requerem aprovação técnica pelos procedimentos de licenciamento ambiental, outorga de direito de uso de recursos hídricos e outorga de autorização de exploração do potencial hidráulico.

Abstract:

This master thesis treats the development of a new component in a tidal energy power plant. The technology that the component should be used in extracts energy from tidal an low velocity currents. This is done by that a turbine is placed on a kite which is pushed forward in the water due to the lifting force acting on the wing. A tether connects the kite with a bottom joint that is placed on a foundation at the seabed. The bottom joint used today is heavy and expensive, which was the main reason to that this thesis was initiated. In this work, the possibility of using a polymer based design fo
