A case study of a voltage rise problem due to a large amount of distributed generation on a weak distribution network

The paper is a case study about the integration of a relatively large amount of distributed generation into a weak distribution network. The main focus is on a comparison of methods to increase the integration capacity of distributed generation and on technical requirements from the distribution network company's point of view. The methods studied do not require major investments in the network. The paper considers voltage issues and the load transfer capability of a distribution network including wind power mills. The studies are based on real-life distribution network and load curve data.
