Distributed generation – new technical solutions required in the distribution system
Författare
Summary, in English
The share of distributed generation (DG) is expected to grow rapidly in near future. In
addition to the environmental aspects also the shorter construction period can be considered as
a key driving force accelerating the development. However, there are also some severe
barriers before wider employment of DG is possible. One of them is the connection to
network or grid. Especially when we consider distribution networks the situation is totally
new since traditionally there are practically no production units connected in the distribution
network. For this purpose new rules and recommendations are needed. Furthermore, new
technical solutions are necessary to make DG economically more viable.
This paper is based on Nordic research project CODGUNet, where the issues relating to the
interconnection of DG units were studied. In this paper different DG technologies are briefly
introduced focusing on network interconnection. After that the impact of DG on the
distribution network is evaluated considering the issues relating to system operation, control,
and protection as well as power quality.
At the end of the paper some key development areas in the distribution system are pointed
out, considering the new requirements arising from the increased share of DG.
