Energy supplied from biogas power station to the distribution network

Biogas stations have become a significant renewable energy source over the recent years. Renewable energy sources are often characteristic for their unpredictable operation and they cause problems within the distribution network. That was why we focused on measurement conducted on a specific biogas station with evaluation of its operation. The measurement ran for two months and involved the automatic measuring gauge ENA 330. The values obtained by measurement were used for evaluation of courses, mainly for output and voltage. The results indicate a certain voltage imbalance, however, it still complies with the applicable standards. Further section deals with spectra of harmonics at higher levels. Those also comply with the standard CSN EN 50 160. The current procedure in progress deals with identification of their potential sources and options for their elimination. This paper forms a part of a long-term research process.
