John's University, , Sec. An overview of new and current developments in state of charge SOC estimating methods for battery is given where the focus lies upon mathematical principles and practical implementations. As the battery SOC is an important parameter, which reflects the battery performance, so accurate estimation of SOC cannot only protect battery, prevent overcharge or discharge, and improve the battery life, but also let the application make rationally control strategies to achieve the purpose of saving energy. This paper gives a literature survey on the categories and mathematical methods of SOC estimation. Rising crude oil prices and worldwide awareness of environmental issues have resulted in increased development of energy storage systems. The battery is one of the most attractive energy storage systems because of its high efficiency and low pollution [ 1 ]. There are several kinds of batteries currently being used in industry: lead-acid battery, Ni-MH battery, Ni-Cd battery, and Li-ion battery.

A phasor measurement unit PMU is a device used to estimate the magnitude and phase angle of an electrical phasor quantity such as voltage or current in the electricity grid using a common time source for synchronization. PMUs are capable of capturing samples from a waveform in quick succession and reconstructing the phasor quantity, made up of an angle measurement and a magnitude measurement. The resulting measurement is known as a synchrophasor. PMUs can also be used to measure the frequency in the power grid. A typical commercial PMU can report measurements with very high temporal resolution, up to measurements per second. This helps engineers in analyzing dynamic events in the grid which is not possible with traditional SCADA measurements that generate one measurement every 2 or 4 seconds.

Zanni, Lorenzo. An increasing number of phasor measurement units PMUs are being deployed in power systems in order to enhance the situational awareness and, in the near future, we expect that many networks will be extensively equipped with PMUs. PMUs are commonly associated with transmission systems, but are gaining consideration also in the context of distribution networks in order to implement fast control schemes due to the presence of highly-volatile distributed generation and for fault location purposes. Power-system state estimation SE is a functionality that might largely benefit from the use of synchrophasor measurements. Best current practice consists in estimating the state every few tens of seconds or even minutes by using asynchronous measurements of RTUs.

Metrics details. With the rapid development of the smart grid and increasingly integrated communication networks, power grids are facing serious cyber-security problems. This paper reviews existing studies on the impact of false data injection attacks on power systems from three aspects. First, false data injection can adversely affect economic dispatch by increasing the operational cost of the power system or causing sequential overloads and even outages.

Клушар приложил руку ко лбу. Очевидно, волнение отняло у него все силы. Его лицо залила мертвенная бледность. Беккер предпринял последнюю попытку: - Мистер Клушар, я хотел бы получить показания этого немца и его спутницы. Вы не скажете, где они могли остановиться. Клушар закрыл глаза, силы покинули. Он едва дышал.
