Impact of biogas plant on distribution grid

This paper focuses on biogas plants with combined heat and power production and their impact on line voltage. It provides a description of a specific biogas plant subject to a longer measurement. The description reveals the course of measurement followed by essential statistical data pertaining to selected values. Further indicators include bar charts for voltage showing a certain asymmetry in the grid and describing the distribution of individual voltage readings obtained by measurement. The main body of this paper further contains the regression model of voltage established by the statistical software that describes characteristics of voltage in the grid with respect to the electric current supplied. The dependence of voltage on current implied by the model is fairly low.
