There　is　a　certain　difference　between　the　ultra-short-term　wind　power　forecast　and　the　actual　output　power　in　the　real-time　market,　though　it　is　smaller　than　that　in　the　day-ahead　market,　therefore,　the　influence　of　wind　power　uncertainty　on　the　output　power　regulation　of　real-time　market　should　be　researched.　According　to　the　normal　distribution　characteristics　of　wind　speed　in　short　period,　the　expression　of　wind　power　distribution　and　its　error　probability　are　deduced,　and　the　dispatch　model　of　output　power　regulation　based　on　the　quoted　price　is　built　for　real-time　market,　which　takes　the　minimum　sum　of　regulation　cost　of　general　generator　and　error　cost　of　wind　power　forecast　as　its　objective　function.　A　specific　case　is　taken　to　analyze　the　influence　of　normal　distribution　parameters,　wind　power　forecast　and　penalty　coefficient　on　the　output　power　regulation　cost,　the　error　cost　of　wind　power　forecast　and　the　error　expectation　is　analyzed　for　the　real-time　market.　Simulative　results　verify　the　effectiveness　of　the　proposed　model.　©,　2015,　Electric　Power　Automation　Equipment　Press.　All　right　reserved.
