針對迎峰度冬期間用電負荷持續(xù)增長、電力內供外送形勢偏緊的情況，國家電網有限公司西北分部超前謀劃，多措并舉，精心安排電網運行方式，確保電網安全穩(wěn)定運行和電力可靠供應。
國網西北分部加強供需形勢分析研判，密切關注天氣變化，滾動負荷預測分析，狠抓新能源出力預測準確率，優(yōu)化機組開機方式，確保全網電力電量平衡；重點針對負荷高峰時段的送出能力進行安全校核，統(tǒng)籌全網電力資源，發(fā)揮備用共享與跨區(qū)跨省支援優(yōu)勢，確保電力內供外送安全。
同時，國網西北分部強化主網安全管控，針對冬季頻發(fā)的極端惡劣天氣編制反事故預案，提前做好預控措施；創(chuàng)新應用一體化安全管控平臺，實時感知電網運行態(tài)勢，評估電網運行風險，提供輔助控制策略，實現電網精準柔性調節(jié)；嚴控網內重要輸電通道潮流，嚴禁超穩(wěn)定限額和設備能力運行，嚴格執(zhí)行電壓控制曲線，加強樞紐變電站無功電壓監(jiān)視和控制。此外，國網西北分部統(tǒng)籌做好黃河防凌工作，合理安排龍羊峽、劉家峽水庫出庫計劃，科學利用劉家峽防凌庫容，滿足負荷高峰時段發(fā)電與綜合利用需求。
