The decrease of fossil fuels resources and an opportunity of being independent from import of fuels led to a situation where more attention is paid to electricity production from biomass. Additional impulses for development of these technologies are law regulations connected with reduction of greenhouse gas emissions. In medium and large scale, combined gas steam cycles integrated with biomass gasification are a very interesting solution. The main advantage of these systems is a relative high energy efficiency. In the paper, model of gas generator and models of gas steam cycles integrated with biomass pressurized gasification are presented. In particular, considered systems consist with gas generator model which use two equilibrium reactors, simple gas turbine, 1-pressure heat recovery steam generator and condensing steam turbine. The simulations include evaluation of the impact of gasification pressure on gasification parameters and the impact of pressure ratio in compressor on efficiency and power of the systems. In the work results of two different configurations of gas cooling are shown.
