In this paper Static Synchronous Compensator (STATCOM) is used for improving the performance of the power grid with wind turbine that drives synchronous generator. The main feature of the STATCOM is that it has the ability to absorb or inject rapidly reactive power to grid. Therefore the voltage regulation of the power grid with STATCOM device is achieved. STATCOM also improves the stability of the power system after occurring severe disturbance such as faults, or suddenly step change in wind speed. The proposed STATCOM controller is a Proportional-Integral (PI) controller tuned by Genetic Algorithm (GA). An experimental model was built in Helwan University to the proposed system. The system is tested at different operating conditions. The experimental results prove the effectiveness of the proposed STATCOM controller in damping the power system oscillations and restoring the power system voltage and stability.
distributed generation resources near the load centers. The
connection of distributed generation to the distribution grid may influence the stability of the
power system, i.e. angle, frequency and voltage stability. It might also have an impact on the
protection selectivity, and the frequency and voltage control in the system. This paper presents a
low cost FACTS based Dynamic Distribution System Compensator (DDSC) scheme for voltagestabilization and power transfer and quality enhancement of the distribution feeders connected to a
dispersed wind generator, using MATLAB
In this note the ratio of the second to the first order reflection is determined for the KAP and PbSt crystals, for wavelengths corresponding to the Al K-line emission. The source of the radiation was a low-voltage stabilized X-ray tube. The X-rays were detected with a Bragg spectrometer equipped with a proportional counter detector. The signal measured by the proportional counter was subsequently pulse height analyzed.
Development of smart grids for power supply to rural consumers assumes the creation of adaptive voltage regulation systems in 0.38 … 10 kV electrical networks as one of the directions. This paper considers a new approach to create an algorithm for controlling the technical means of regulation and voltage stabilization. The proposed adaptive voltage regulation system allows collecting and processing information on the actual voltage at the consumer inputs and automatically determine the voltage regulation coefficient. The developed mathematical model allows calculating the voltage regulation coefficient depending on the voltage at various points of the 0.38 kV electric network. In the paper there are also new methods of adaptive automatic voltage regulation in the 0.38 kV electrical networks and the requirements to the functional capabilities of this system. The article suggests technical solutions for the implementation of adaptive automatic voltage regulation system. The successful tests of experimental model of this system have been carried out.

However, increased penetration of dispersed and distributed wind energy
creates a new serious uncontrollable scenario in electric power grid system. On
one hand, dynamic variations and wind velocity excursions cause excessive
changes in prime mover power and the corresponding electrical power injected
into the grid utility network. Depending on intensity and rate of wind changes,
difficulties with generator output frequency variations and severe generator
voltagestabilization could result in possible loss of
