nonanalytic
Examples
- 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
本文基于netomac仿真软件，以发电市场预调度计划模型及算法、励磁系统参数整定和电力系统小扰动稳定性分析为研究内容，主要做了以下工作：建立了以整个预调度计划周期内的市场购电价格最小为目标的发电市场预调度计划模型，并根据预调度计划问题状态数多、变量多、混合整数、非解析的特点，将预调度计划模型的目标函数简化为各时段的市场清算电价最小，设计了三段式预调度算法：用静态规划法求解整个预调度计划周期内的优化问题；用优先级法求解机组组合问题；用改进的powell法求解最优潮流问题。
