  4. 3. Development and validation of a combined heat and power plant model for integration in DYESOPT

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : José Angel García; [2018]
    Keywords : ;

    Abstract : The liberalization of electricity markets and a growing penetration of renewables has led many countries to feel changes in the operation of their grids. The boundary conditions for the operation of conventional power plants are changing and, as such, an improved understanding of the varying loads and prices on the electricity grid is required to assess the performance of emerging combined cycle gas turbine (CCGT) concepts and to further optimize their design for these new markets in the pursuit of increasing their profitability, especially when considering co-generation of heat and power.
