Interconnection of distributed power to the distribution network

摘要

The interconnection of distributed power resources, normally through a power electronic converter, to the distribution network brings challenges of its own. Due to the distributed nature of these resources, they are implemented in large numbers onto the same, sometimes remote, distribution network. These challenges include power quality issues, network stability, power balancing considerations, voltage regulation, protection protocols and unwanted islanding considerations. This paper highlights some of these issues with the aid of two case studies in large-scale PV and wind power interconnections, sensitizing some of the underlying considerations.
