The mathematical model of the three-phase grid-side PWM converter in d-q synchronous reference frames is thoroughly investigated. Comparing with the tradition control way of PWM converter. this method doesn’t demand high accuracy of mathematic model. and has little sensitivity of parameter change and the external perturbation. which can control a …

This work has been devoted to modeling. simulation and analysis of a wind turbine operating at variable speed. A stable operation of the wind energy system is obtained with the application of nonlinear Backstepping Adaptive control. The overall operation of the wind turbine and its control system were illustrated by …

The second meeting of the working group is planned to be held in Moscow.

The increasing development of large-scale offshore wind farms around the world has caused many new technical and economic challenges to emerge. The capital cost of the electrical network that supports a large offshore wind farm constitutes a significant proportion of the total cost of the wind farm. Thus. finding the …

Randomness of wind speed around a short-durationstable mean value is commonly referred to as short duration wind variation. This paper investigates the effect of substantial windbased capacity inclusion on optimal load dispatch. with the source wind susceptible to short duration variations. Analytical formulation of the economic load dispatch (ELD) problem …

The private power producers are increasing rapidly to meet rising load demand in domestic. commercial. and industrial sectors. In this scenario. the distributed generation systems (DGs) play an important role over fossil fuel generation. Among different distributed generation technologies such as fuel cell. wind power. and solar. the fuel-cell-based distributed …

This paper proposes a method of modeling and simulation of photovoltaic arrays. The main objective is to find the parameters of the nonlinear I–V equation by adjusting the curve at three points: open circuit. maximum power. and short circuit. Given these three points. which are provided by all commercial array …

We present a non-traditional CMOS inverter composed a junctionless (JL) NMOSFET and an N+ -N–P transistor which with simple process and high integration density in this paper. In the non-traditional CMOS inverter the JL NMOSFET serves as driver and the N–P transistor serves as load. respectively. Based on the measurement …

The battery energy storage station (BESS) is the current and typical means of smoothing wind- or solar-power generation fluctuations. Such BESS-based hybrid power systems require a suitable control strategy that can effectively regulate power output levels and battery state of charge (SOC). This paper presents the results of a wind …

This book has two purposes. The first is to examine the electromagnetic theory behind many of the calculations relevant to the design of high voltage overhead transmission lines. These include electromagnetic propagation on multiple parallel wires above the earth and their associated fields. electrostatic fields near more complicated geometries. limitations …
