Impact of renewables on relay protection operation

Research output: Contribution to journalArticlepeer-review

Abstract

The current trend in the development of electric power systems is the integration of renewable energy sources in the form of distributed generation. It was revealed that one of the main reasons inhibiting this process is a change in the EPS operating modes, which in turn has a significant impact on the operation of relay protection and automation and, as a consequence, on their setting. A decrease in sensitivity and a violation of relay protection selectivity in distribution network in the case of integration of wind power generation into EPS have been experimentally proved. An important factor is the capacity and location of the wind power generation facilities connection. In addition, the article analyzes the existing approaches to implement the relay protection of such power systems. As a result, it is theoretically proved the need to develop new methods and means for comprehensive setting up of relay protection and automation, since existing approaches either limit the integration of new installations, or they are difficult to implement, or not flexible enough.
