Observability and state estimation of electrical power networks (sinusoidal signals)
The aim of this article is to extract the totality of determinable parameters (measured or deduced) of an electrical power network in stationary state, in view to estimate their true values. These systems, different from conservation-law systems, are described by linear and bilinear equations which involve the complex intensities Ir and Ic, the impedances Zr and Zc, and voltages across the asso...
متن کاملPower System Observability and Dynamic State Estimation for Stability Monitoring Using Synchrophasor Measurements
Growing penetration of intermittent resources such as renewable generations increases the risk of instability in a power grid. This paper introduces the concept of observability and its computational algorithms for a power grid monitored by the wide-area measurement system (WAMS) based on synchrophasors, e.g. phasor measurement units (PMUs). The goal is to estimate real-time states of generator...
متن کاملPower System State Estimation by Novel Approach of Kalman Filter
The electrical network measurements by measuring device Phasor Measurement Device (PMU) are usually sent to the control centers using data acquisition system and other communication protocols available. However, these measurements contain uncertainties due to the measurements and communication noise (errors), incomplete metering or unavailability of some of measurements. The overall aim of stat...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولPOWER SYSTEM STATE ESTIMATION A. Power System State Estimation The conventional method for power system state estimation is the weight least squares (WLS) state estimation
This paper proposes the stochastic tabu search (STS) for improving the measurement scheme for power system state estimation. If the original measured scheme is not observable, the additional measurements with minimum number of measurements are added into the system by STS so that there is no critical measurement pair. The random bit flipping and bit exchanging perturbations are used for generat...
