Description

The evaluation of the smart Grid electrical devices the DC-DC conversion plays very important role. Lot of DC-DC converter in PV was proposed with different topology to obtain Effective Boost voltage with minimum zero steady state error. Among all other converter auxiliary circuit with voltage PV grid system will give significant Boost voltage. In this converter, we implement auxiliary circuit with inverter design in Smart Grid system has switches and Diodes which is controlled by reactive power control by transfer function. In this rectifier circuit has reverse recovery problem in the diode formation. To overcome these drawbacks, VSC blocks are used with Grid system topology. It will be better result among all other conversion method. This Controller design has two different operation modes, one of the systems can serve as master in voltage regulation mode (i.e., selector switch choosing block- B1) and others as slaves in controllable reactive power compensation mode (i.e., selector switch choosing block- B2). All the operational modes can be analyzed and the switching characteristics can evaluated successfully. It can achieve zero steady-state error, integral action must be included in the AC voltage controller with desired phase margin. The Phase shift can be obtained between the primary and secondary side of the FBV-VD-ABR. The power conversion can be obtained using resonant converter design. The output voltage can be compared with the DC reference voltage, which will be feed to the proportional-integral (PI) controller. The proposed strategy is quite simple and goes back to the open loop frequency analysis. If reshaping the amplitude- and phase-frequency response in such a way that dc as well as harmonic frequency .It will give the Phase angel (∅) based on the Error voltage from the output voltage. The output phase angle can be send to the Phase shift modulator. It will modulate the switching operation which will provide the control of the Ac voltage at the primary side. The resultant error DC _DC conversion can be obtain with High gain and zero steady state error. The PV cell is use in many application in present world for its simplicity and advantage. The PV cells output comes DC but in commercial AC is use. In that reasons the DC converts to AC but that conversion there lot of problems are faced like switching loss, conduction loss, harmonic loss, etc. During that loss affect entire output performance of the system. The power loss is major problem today power generation world because in commercial we use the motor in home and use anther heavy nonlinear loads are used in commercial use it reduce the power in grid system. Here we use the renewable energy source for power system. In our proposed we use PV cell for grid system and the power demand rectify by using the Fuzzy logic control system using the auxiliary circuit the fuzzy will desired when the auxiliary circuit is on and off by using the MOFF set switches. The Fuzzy is the rule based algorithm it helps to auto adjust it charterstics based on the rule. If the power demand is analysis by fuzzy it control the switches to activate and deactivate auxiliary circuit.
