Economics and Regulatory Criteria for Distributed Generation

Since electricity systems of nowadays are increasingly penetrated by renewable electricity generation, the integration and political support of distributed generation became a main topic. Moreover, the constantly growing installation of distributed generators is supported in order to better meet the national and international agreements on primary energy savings and CO2 reductions. Hereby, the grid connection approach and the balancing method of distributed generators are important issues. Different approaches cause different investment costs resulting in varying electricity generation costs and changing efficiency rates of the grid utilization. These facts have an intensive impact on the social acceptance among the population and play therefore an important role in political decisions.
