Coordinated voltage control algorithms tested in real time digital simulator

To restrict voltage rise problems and to increase the hosting capacity of distribution network for distributed generation, active voltage control methods have been developed. Two coordinated voltage control algorithms previously created at Tampere University of Technology have been tested and compared by the real time software-in-the-loop tests. The paper also proposes test sequences and metrics to be used in the functional and performance testing of coordinated voltage control algorithms. In this article results from real time digital simulator tests of these algorithms are presented and discussed and suggestions for the future development of the algorithms are also given.
