Q-v Curve Interpretations of Energy Measures for Voltage Security
Energy methods have shown promise as measures for quantifying the vulnerability of power systems to problems of voltage instability and collapse. However, to make such measures more useful as a security assessment tool in an operational environment, it is important to provide physical interpretations of the quantitative measure. This paper will demonstrate that for certain basic load models, th...
متن کاملsupply and demand security of energy in central asia and the caucasus
امنیت انرژی به معنی عرضه مداوم و پایدار همراه با قیمت های معقول در حامل های انرژی، که تهدیدات امنیتی، سیاسی، اقتصادی، محیط زیستی و روانی را کاهش دهد. امروزه نفت و گاز تنها، کالای تجاری نیست بلکه بعنوان ابزار سیاسی مورد استفاده قرار می گیرد.اختلاف میان روسیه و اکراین بر سر انرژی در ژانویه 2006، تهدیدی برای امنیت انرژی اروپا ایجاد کرد. در این تحقیق ما تلاش کردیم که نقش انرژی آسیای میانه و قفقاز ر...
15 صفحه اولVoltage Stability Analysis comparing Generator Sensitivity based Method with V-Q Curve Method for Optimal Placement of STATCOM
This paper compares the coherent groups of load buses based on Reactive Reserve Margin (RRB) obtained from the V-Q curve analysis and a novel generator sensitivity based method for optimal placement of STATCOM. The V-Q curve is one of the popular methods to study voltage instability problems in power systems during the post transient period or critical peak loads. The reactive reserve margin ob...

متن کاملStudy on P-V Curve and V-Q Curve of an Unbalanced Three- Phase System with Different Static Loads
P-V curve and V-Q curve (often term as Q-V curve) are widely used for planning and operation studies. The P-V curve and V-Q curve of an unbalanced three-phase system, unlike the balanced three-phase system, may not have similar loading margin (LM) and reactive power margin (RPM) on each phase. Therefore, DIgSILENT Programming Language (DPL) has been used to study the maximum loading point (MLP)...
