电力系统中的混沌研究与混沌应用

Chaos Studies and Its Applications in Electric Power Systems

混沌作为一个新的研究方向,已渗透到自然科学和社会科学的各个领域。混沌在电力系统的研究虽然只有近20年,但已有大量的混沌现象被研究,如机电系统混沌振荡,以及分叉、混沌与电压骤降,电力经济中的混沌,水轮发电机组调速系统中控制器参数诱发的混沌等。人们在研究和分析、抑制混沌的同时,又在电力系统中应用混沌,如混沌应用于电站经济运行最优负荷分配、静态负荷模型辨识、模糊电力系统稳定器的参数优化以及短期负荷预测,从而全面开创了电力系统混沌的研究、分析与利用新局面。对电力系统中混沌的研究与利用进行了较为全面的分析和总结,对于推动电力系统的混沌研究具有一定的意义。

Although chaos has been studied in electric power systems for only two decades, plenty of chaotic phenomena have been found in power systems, such as chaotic oscillation, bifurcation, voltage collapse, chaos in electric economy, etc. Besides of researching, analyzing and controlling chaos, people are utilizing chaos in electric power systems too, e.g. chaos optimization of economic dispatch, parameter estimation of static load model, fuzzy power system stabilizer, and shortterm load forecasting. The paper analyses and reviews the chaos studies and applications in electric power systems.
