Voltage Variations Originated by the DG Anti-islanding Protection: Evaluation and Mitigation for Maintaining the Power Quality Indices

Anti-islanding protection (AIP) is an important part of the distribution system with distributed generation (DG). Therefore, this protection is required for security purposes. The voltage variations originated by the synchronous DG Antiislanding protection is a recent problem investigated which can violate the power quality (PQ) indices in a distribution system. Moreover, violation of power limits increases with the insertion of more distributed generators in the distribution network. This paper explores the voltage variations while DG anti-islanding protection is activated. Then, we perform a practical solution such as load shedding for maintaining the power quality within its limits, although this is a radical method for distribution companies. Finally, we discuss the results obtained.
