A　wide-area　damping　control　strategy　comprehensively　considering　synchronous　generators　and　doubly　fed　induction　generators　was　proposed　which　is　based　on　the　interarea　low　frequency　oscillation　problem　caused　by　large　area　interconnected　power　grid　and　massive　grid　connected　doubly　fed　wind　farms.　Also,　a　new　optimization　algorithm　called　Mean-Variance　Mapping　Optimization　algorithm　with　the　advantage　of　fewer　iterations　and　not　easy　to　fall　into　local　optimal　solution　was　adopted　to　coordinate　the　configuration　of　controller　parameters.　And　the　superiority　of　this　new　method　is　proved　by　contrast　with　the　traditional　intelligent　algorithms.　At　last,　interarea　low　frequency　oscillation　problem　in　interconnected　power　systems　with　massive　grid　connected　doubly　fed　wind　farms　was　effectively　solved　by　the　proposed　method,　which　is　validated　by　the　simulation　results　a　four-machine　and　two-region　test　system　with　a　doubly　fed　wind　farm.　©,　2015,　Editorial　Department　of　Electric　Machines　and　Control.　All　right　reserved.
