Based on netomac, a software package for power system simulation, the model and algorithm of pre - dispatch schedule in generation markets, excitation system parameter setting, and power system small signal stability anaylsis are studied in this thesis. the main work is as follows : a model of pre - dispatch schedule is proposed, whose target is to minimize the market purchasing price ( mpp ) in the whole pre - dispatch period. then according to the characteristics of pre - dispatch schedule, the model of pre - dispatch schedule is simplified to minimize the mpp in each pre - dispatch time, and a three - step algorithm of pre - dispatch schedule is designed : dealing with the optimal problem in the whole period of pre - dispatch with static planning method, solving the problem of combination of machines with pr1 method, resolving problem of optimal power flow ( opf ) with modified powell method
本文基於netomac模擬軟體,以發電市場預調度計劃模型及演算法、勵磁系統參數整定和電力系統小擾動穩定性分析為研究內容,主要做了以下工作:建立了以整個預調度計劃周期內的市場購電價格最小為目標的發電市場預調度計劃模型,並根據預調度計劃問題狀態數多、變量多、混合整數、非解析的特點,將預調度計劃模型的目標函數簡化為各時段的市場清算電價最小,設計了三段式預調度演算法:用靜態規劃法求解整個預調度計劃周期內的優化問題;用優先級法求解機組組合問題;用改進的powell法求解最優潮流問題。
