Value-Based Evaluation of Power System Planning Alternatives with Large-Scale Wind Power
摘要: 從全社會成本視角出發，構建了含大規模風電的電力規劃方案評估的總體框架．其中，為計及風電出力波動性的影響，針對給定的規劃方案和全年時序的風電出力與負荷數據，通過內嵌機組組合優化模型、計及靜態和動態安全約束的經濟調度模型(動態安全域邊界的超平面形式可使動態安全約束處理難的問題變得十分簡易)及校正性控制模型，實現系統運行過程的模擬，從而可詳細評估全年每小時的系統燃料、環境、網損成本以及系統可靠性成本．再結合電源的容量成本和電網成本，則可獲得方案的全社會成本，實現規劃方案的全社會成本評估．最后通過示例分析驗證了方法的有效性．

摘要:
- Abstract:
- From the perspective of the total social cost，the overall framework of evaluation of power system plan-ning with large-scale wind farms was established. According to the annual chronological hourly data of wind power and load，for a given power system planning alternative，its system operation simulation was carried out，wherethe variability of wind power was considered. In the simulation process，daily-ahead(or week-ahead)unit commitment model，steady state and dynamic secutiy constraints based economic dispatch model and remedial control model were included. It was emphasized that based on the hyper-plane description of the bounary of the practical dynamic securityregion(PDSR)，the difficulty of dealing with stability constraints in the problem of solving for steady state and dy-namic secutiy constrained economic dispatch can be overcome easily. Hence the hourly fuel，environmental and net-work loss cost in the year for the given planning alternative could be calculated. These costs were to be combined with generation capacity cost，power network cost and system reliability cost，so that the total social cost of the alterna-tive could be determined. Therefore the evaluation of the total social cost of an alternative was achieved. Finally，the proposed method was validated by means of the case studied.
