Verification of cooperative control method for voltage control equipment on distribution network simulator considering interconnection of wind power generators

This paper verifies the developed cooperative control method for voltage control equipment on distribution network simulator considering interconnection of wind power generators. The authors have developed a cooperative control method for existing voltage control equipment and newly developed voltage compensating equipment applying power electronics technology. The developed control method can handle various steep voltage fluctuations such as large steep generating power fluctuations of wind power generators and electrical flickers such as little periodical fluctuation by a tower shadow effect of wind power generators. The developed method has been applied to typical distribution models on analog distribution network simulator (15 kVA/200 V). The results indicate that the proposed method can regulate the line voltage within the regulated voltage ranges and can reduce electrical flickers.
