文摘
- •
A new approach is proposed to solve relays miscoordination in interconnected systems arising from DGs.
- •
It deduces the minimum value of FCL impedance in combination with settings change for minimum number of relays.
- •
It studies the possibility to obtain new settings for only one adaptive relay while using minimum value of FCL to achieve coordination.
- •
The proposed approach is extensively tested on IEEE-39 bus test system.
