In　view　of　the　shortcomings　of　traditional　stochastic　programming　and　interval　optimization　methods　for　handling　wind　power　uncertainty,　a　two-stage　robust　cooperative　scheduling　model　for　the　electricity-gas　integrated　energy　system　with　PtG　facilities　is　proposed,　and　the　influence　of　natural　gas　network　operation　constraints　on　the　scheduling　power　output　and　reserve　capacity　configuration　by　gas-fired　units　and　PtG　facilities　is　considered.　The　sum　of　the　day-ahead　dispatch　cost　under　wind　power　benchmark　scenario　and　the　real-time　dispatch　cost　under　the　worst　wind　power　scenario　is　regarded　as　the　objective　function,　and　a　bi-level　optimization　model　with　max-min　structure　is　established.　Then　the　solution　is　obtained　by　using　the　column-and-constraint　generation　method　through　the　master-sub　problem　solving　framework.　Finally,　a　simulation　example　is　built　on　Mathlab　platform　to　verify　the　effectiveness　of　the　proposed　two-stage　robust　cooperative　scheduling　model.　©　2022,　Solar　Energy　Periodical　Office　Co.,　Ltd.　All　right　reserved.
