Renewable energy deployment through distributed resources is among the central goals of future power systems. Microgrids have proven to be an economically viable solution for resources’ integration into system and benefits customers with uninterrupted supply. In this context, provisional microgrids been introduced main goal rapid renewable resource deployment. Since a considerable portion resou...

A novel topology of three-phase hybrid converter (TP-HC) which can supply simultaneously both DC and AC loads is presented. This obtained by adding three switches to T-type three-level inverter. Consequently, this achieve one group DC/DC power transformation another voltage outputs with adjustable amplitude. The operation modes the proposed are introduced. Then working principle available switc...

With the increase of power load and access distributed generation, AC/DC hybrid distribution network will become development trend urban in future. The core generation are voltage source converters based on full control switches. This paper simply analyzes operation principle mode converters, a flow calculation method system is proposed, optimization model with minimum loss deviation DC establi...

Most of the ac-ac converters used in home-appliances are based on single-output dc-link inverters, which provides a cost-effective and straight-forward solution. However, this twostage power conversion decreases power density and efficiency. Direct ac-ac conversion has been thoroughly studied in the past. However, the complex control scheme and higher cost has prevented it from being used in lo...

The hybrid micro gird is growing due to the potential benefits in providing safe, reliable and sustainable electricity from renewable energy sources. In this paper, we are discussing the multiple energy sources i.e. PV/Fuel cell and wind based hybrid microgrid with help of simulation approach to improve the power quality in microgrid with ANN control. The artificial neural network control is us...

Two aphidicolin-resistant cell mutants (AC 12 and AC 41) with a fourfold increase in spontaneous frequency of sister chromatid exchanges (SCEs) were obtained out of over 400 aphidicolin-resistant mutants isolated from mouse lymphoma L5178Y cells. They also exhibited three- to fourfold increases in spontaneous frequency of chromosome aberrations (CAs). To determine whether the high level of SCE ...

In this paper a new method is proposed for determining PID controller parameters in order to decrease losses in levitation system of magnetic trains. It is assumed that this system is a hybrid system and it consists of electric and permanent magnet. For optimization of losses initially AC losses of magnetic levitation system are calculated. Linear model of levitation system as well as modeling ...
