“…of nominal one, undergoes maximum relative error of stabilization module of equivalent load eqv Z equal to 10% and equivalent phase ϕ eqv -17%. Such stabilization error of hydro-generator load may lead to the frequency stabilization error of the generated voltage in the range of 50 ± 2.5 Hz [6]. Applying the generator with armature winding taps enables to improve stabilization module of the plant equivalent load.…”

In the paper operating mode simulation of a hydro-generator with armature winding taps, running under standalone load with thyristor auto ballast stabilization system of magnitude and frequency of the output voltage of a hydraulic unit has been conducted. The created model enabled to investigate steady-state operation of the plant when connecting ballast load to various winding taps of the hydraulic generator subject to power change of the plant workload. Stabilization of the magnitude and phase of hydro-generator equivalent load as well as the distortion degree of output voltage for each stage of ballast have been evaluated. Ballast stage control algorithm and control laws of gate switching angles of ballast regulator have been proposed. Studies were undertaken within the scope of the RFBR grant entitled “Research and development of micro hydro power plant control systems for the power supply of standalone consumers”.

“…Due to all the inputs and all the outputs of the system are coupled, a decoupling operation at the plant input can be implemented using the inverse matrix of H R [13], which is denoted as J, see equation (15). Equation ( 16) shows the interaction of the control loops can be eliminated, where I e , defined as the estimated value of the current vector, is the new input of the system.…”

“…Although it is possible to decide if the battery is charging or discharging by controlling the port current, which is already done, the ripple currents can cause severe problems, LC filters are added to the ports and a controller is designed in order to avoid abrupt changes in the current. The battery current reference value could be calculated from a management algorithm [15]. For this case, a lead-lag compensator is used.…”

In a solid state transformer (SST), one of the most important roles is played by the dc-dc converter interfacing the high voltage port and the low voltage port while providing galvanic isolation. This paper proposes a quad-active-bridge (QAB) converter as the basic cell of a Modular Multilevel Converter (MMC) based solid state transformer for the integration of distributed energy resources (DER) and distributed energy storage systems (DESS) into the grid. This study comprises power transfer analysis, modeling and control of the QAB for this application. Furthermore, this paper shows an alternative method based on the star-mesh transformation to built the multiwinding tranformer equivalent circuit, that relates any two ports of the multiple-active-bridge (MAB) converter through a link inductance, which allows to describe power flow. Results are obtained by simulations in PLECS.

“…Graphene is a molecule which is thick, two dimensional, and one of the allotropic kinds of carbon arranged every so often in a honeycomb framework. Graphene is less expensive and use less energy in electronics like smart phones because of its superior optical and thermal properties [13].The most popular IBM exhibit graphene transistor which having special features than previous experimental transistors [14][15][16]. These transistors can perform 155 billion cycles per second and about 50% faster.…”

This paper studies that graphene is one of the best option for sustainable future energy requirements of world. Utilizing the blend of natural and inorganic cells makes graphene cell having uncommon highlights which encourages us to get super properties. The transparent and conductive films based on grapheme were shown to be financially savvy with high thermal and electrical conductivity. Graphene is comprised of a solitary layer of carbon atoms that are fortified together in a rehashing example of hexagonsIt is a 2 dimensional material with astounding qualities like amazingly solid and primarily transparent and furthermore incredibly conductive and adaptable. Graphene is made of carbon, which is bounteous, and can be a generally economical material.. Graphene has an apparently unending potential for improving existing items just as rousing new ones. In this article, need of graphene material, advantage over PV material, structure, properties and utilizations of graphene are reviewed.
