摘要
本文从提高电力系统静态稳定性、改善电压和减少网损出发,提出了一个综合性能指标和相应的目标函数。综合性能指标体现了无功/电压控制的安全目标,目标函数体现了经济目标。为避免灵敏度法的求逆运算,以便提高速度、减少内存量,应用直接法并采用适合于经济运行的对偶单纯形法求解。变步长和松驰技术的应用使寻优速度更快。
For improving steady-state stability and voltage profiles and minimizing transmission loss, a comprehensive index together with a corresponding comprehensive objective function is proposed, which represent the objective of security and the economic respectively. To avoid any matrix inversion in sensitivity method, i.e., to save computing time and memory space, a direct method is used to form optimal problems. The simplex dual method with changing step size and constraint relaxation strategy saves the optimal searching time.
