Control and protection of distribution systems with distributed generators

Unquestionably, in the last years, the number of generators connected directly to electric power distribution systems has increased. In addition, the main statistics and signals show that such tendency could become even more intense in the coming years. As a consequence of this policy, many technical factors related to control, protection, operation and analysis of distribution systems should be reformulated and revised in order to allow for these generators to be suitably installed without having the global power quality and reliability indexes network deteriorated. Therefore, the objective of this paper is to present an overview on control, protection, operation and analysis of distribution systems with high penetration level of distributed generation.
