A new method for ferroresonance suppression in an IEEE 33-bus distribution system integrated with multi distributed generation

Abstract

Although integrating a distributed generation (DG) into a distribution system (DS) has several benefits, it may be accompanied by some issues, such as ferroresonance. Therefore, ferroresonance investigations in an integrated DS with multi-DGs have been identified as a research gap. To this end, this paper presents a new method to mitigate ferroresonance in distribution networks, after which ferroresonance in an IEEE-33 bus radial DS integrated with multi-DGs was investigated. Here the RLC shunt limiter is introduced as a method for mitigating ferroresonance, including a design approach for adjusting its dimensions to fit the system. Investigations revealed that this shunt relied on the negative sequence detector to connect it to the system during ferroresonance. Finally, the effectiveness and superiority of the proposed method have been demonstrated by comparing its result with those obtained using other existing ferroresonance mitigation methods used in the literature.
