Abstract

This study investigates the time-delayed frequency control of a 14-bus power system incorporating wind turbine (WT) deloading through rotor overspeed control (RSC), modeled using DIgSilent PowerFactory. To enable frequency regulation, variable-speed WTs operate under a power–rotor speed-based deloading scheme, while rotor kinetic energy control is employed to provide virtual inertia support to the power system. In addition, to support the inertia to the power systems by WTs, the kinetic energy control of the rotor is utilized. However, communication network-induced time delays arise from the transfer of measurement and control signals between generating units and the control center. These delays may degrade the dynamic performance and negatively impact system stability, making delay-dependent stability analysis essential. Therefore, this study examines the delay-dependent stability characteristics of the frequency control system with WT deloading in the DIgSilent PowerFactory environment. The results demonstrate that the participation of deloaded WTs with rotor kinetic energy control enhances both the stability and dynamic performance of the time-delayed frequency control system.

Özet

Bu çalışmada, DIgSilent PowerFactory ortamında rotor hız kontrolü (RHK) tabanlı rüzgâr türbini rezerv güç kontrolü içeren 14 baralı bir güç sisteminin zaman gecikmeli frekans kontrol sistem modeli incelenmiştir. Değişken hızlı rüzgâr türbinleri frekans kontrol sistemlerine dahil edilebilmeleri için güç-hız eğrisi üzerine dayalı rezerv güç oluşturulmaktadır. Bununla birlikte güç sistemine atalet desteği sağlamak amacıyla rüzgâr türbinlerinde rotor kinetik enerji kontrolü kullanılabilmektedir. Ancak, güç sistemlerinde üretim birimleri ile kontrol merkezi arasında ölçüm ve veri transferlerinden kaynaklı olarak sistemin dinamik performansını olumsuz etkilenen zaman gecikmeleri görülebilmektedir. Bu durum, güç sistemlerinin çalışmasını olumsuz etkileyerek sistemin zaman gecikmesine bağlı kararlılık analizini gerektirmektedir. Bu çalışmada, DIgSilent PowerFactory ortamında oluşturulan rezerv güç kontrollü rüzgâr türbini içeren frekans kontrol sistemlerinin zaman gecikmesine bağlı kararlılık analizi incelenmiştir. Rüzgâr türbinlerinde rotor kinetik enerji kontrolü ve rezerv güç kontrol tekniklerinin güç sistemlerine ilave edilmesiyle zaman gecikmeli frekans kontrol sisteminin kararlılığının iyileştiği ve daha iyi bir dinamik performans ile çalıştığı görülmüştür.
