The paper focuses primarily on description of the function model, simulating the electrical output of biogas station. The main objective of the model itself is to create a simulation of electric power course which is supplied to 22kV distribution grid from biogas stations. Therefore, the article contains the basic principle of the draft biogas-station model and describes its main functional elements. It also describes the basic parameters of input data. The main objective of the model is to create a simulated course of electric power supply unlimited by time to 22kV distribution grid. Subsequently, a combination of this model output together with other models and simulations of renewable energy sources and 22kV systems is expected. Above all, cooperation with photovoltaic power plant is assumed. The result of the cooperation of each model representing the selected elements of distribution grid, especially renewable sources, should then be a clarification of the possibility of connecting biogas stations to the 22 kV distribution grids. It should result providing additional options of stabilizing grids at 22kV level, possibly with a connection of biogas-station to distributin grid in terms of possible support services. A basic fact identified by both the long-term measurements and the output of the simulator is that biogas-station with conventional combustion cogeneration units are reliable and stable sources of power supply.
