Research on Damping Control Index of Ultra-Low-Frequency Oscillation in Hydro-Dominant Power Systems

wind farm impact on generation adequacy in power systems

در سال های اخیر به دلیل افزایش دمای متوسط کره زمین، بشر به دنبال روش های جایگزین برای تامین توان الکتریکی مورد نیاز خود بوده و همچنین در اکثر نقاط جهان سوزاندن سوخت های فسیلی در نیروگاه های حرارتی به عنوان مهم ترین روش تولید توان الکتریکی مطرح بوده است. به دلیل توجه به مسایل زیست محیطی، استفاده از منابع انرژی تجدید پذیر در سال های اخیر شدت یافته است. نیروگاه های بادی به عنوان یک منبع تولید توان...

Synchronization of Low-Frequency Oscillation in Power Systems

This paper presents the well-documented concept of synchronization of low frequency oscillation occurring in power systems and describes the characteristics of sync occurring in basic electrical circuits. The theory of sync, observed in basic circuits, is extended to analyze the dynamic characteristics of low-frequency oscillation in power systems.

Optimal Adjustment of Three-Term Controller and Two-Term Compensator Performances in Hydro Power Systems for Load Frequency Control

An important issue with respect to the hydraulic power systems is the frequency stabilization. To design Load Frequency Control (LFC) with high efficiency, control parameters need to be adjusted so that the system frequency remains stable even under changeable conditions. Controlling the frequency and changes in the turbine time constant requires that three term control parameters of Proportion...
