Area of Science:

• Electrical Engineering
• Power Systems Engineering

Background:

• Integrating distributed generation (DG) into distribution systems (DS) offers benefits but introduces challenges like ferroresonance.
• Ferroresonance in distribution systems with multiple DGs is a significant research gap.

Purpose of the Study:

• To address the research gap by investigating and mitigating ferroresonance in a distribution system with multiple DGs.
• To present and validate a new ferroresonance mitigation method.

Main Methods:

• A novel RLC shunt limiter was designed and implemented for ferroresonance mitigation.
• The RLC shunt limiter's dimensions were optimized for the specific system.
• Ferroresonance in an IEEE-33 bus radial DS integrated with multi-DGs was investigated.
• A negative sequence detector was utilized to activate the shunt limiter during ferroresonance.

Main Results:

• The proposed RLC shunt limiter effectively mitigated ferroresonance in the integrated distribution system.
• The RLC shunt limiter demonstrated superior performance compared to existing methods.
• The negative sequence detector successfully triggered the shunt limiter during ferroresonance events.

Conclusions:

• The developed RLC shunt limiter is an effective solution for ferroresonance mitigation in multi-DG distribution systems.
• The proposed method offers a reliable and superior alternative to existing ferroresonance control strategies.
• Further research can explore the application of this method in more complex power system configurations.
