The Z-source concept has many advantages it can be applied for any type of power conditioning system this paper propose a Z-source based three level inverter system for the photo-voltaic array or system. A comparison of traditional system and new Z source three level inverter configuration is performed. In this paper present the SPWM technique for controlling the neutral clamped three level inverter...
In this paper design and application of bidirectional push pull converter in Microgrid Systems has been discussed. A push-pull converter is suitable for boost applications, because the step up ratio of high frequency transformer is high. It is possible to use Push pull converter for achieving higher voltages on input side of inverter. The proposed push pull converter is designed to operate in Bidirectional...
This paper focus on specially designed DG based Power Quality Conditioner for Micro Grid applications. Three leg inverter coupled with solar PV with MPPT used as Compensator can be used for distinct DGs in the micro grid for power quality improvement of the entire system. Optimum control can be achieved to avoid detraction for voltage, current and Power flowing between Grid and DG. By adjusting power...
Back to back (B2B) voltage source converter is used for HVDC system and ac drive system to control active-reactive power. In this paper reduced switch back to back converter is used for induction motor drive system which is operated in unity as well as leading power factor. Active and reactive power flow are independently controlled. The active power transfer is controlled by angle delta; where delta...
This paper presents work related to management of active and reactive power exchange between a distributed generation (DG) source and the grid to which it is connected; for improved utilization of electricity generated by the DG source such as solar energy. This is based on the recently introduced Availability Based Tariff (ABT) concept for the consumer loads, where conventional power grid is available...
There has been a gradual increase in generation of power from renewable energy resources interfaced to existing utility grid to increase its reliability. Tapping of these resources is done in multiple ways like standalone wind generators or photovoltaic plants, microgrids etc. Interfacing DC sources like photovoltaic cells, battery, fuel cells with AC systems requires tie line inverter with robust...
