Novel Method

This paper proposes a novel method for the analysis of photovoltaic system under unreliable condition. The photovoltaic system is the combination of large number of PV cells connected in series. The photovoltaic system plays a great role in reducing the global warming and maintaining the ecological balance by promoting to the green environment. The photovoltaic system replaces the conventional method of generating electricity to the non-conventional method of generating electricity. This paper focus on distinguishing the performance of photovoltaic system under uniform condition and non-uniform unreliable condition through the solar GIS tool.

Auxiliary Mass

This paper presents the design of an efficient non-linear vibration absorber. The system comprises a linear absorber with the addition of a spring between the two masses, which contacts the absorber mass when its displacement exceeds a certain value. The addition of this snubber stiffness facilitates a reduction in the amplitude of the second resonance peak of the linear absorber, which therefore enables the system to be operated over a wider frequency range without reaching larger amplitudes. The modification also has the effect of attenuating the response of the auxiliary mass. The equations of motion for the system are presented and optimization is carried out. A description of an experimental rig that was built follows. The results from the rig are compared with those from numerical simulation and show good correlation.

<span>Voltage-source converter (VSC) topology is widely used for grid interfacing of distributed generation (DG) systems such as the photovoltaic system (PV). Since the operation of the VSC is essential to ensure quality of active and reactive power injected to the grid, a control approach is needed to deal with the uncertainties in the grid such as faults. This paper presents a non-linear controller design for a three-phase voltage source converter (VSC). The dynamic variables adopted for the VSC are the instantaneous real and reactive power components. The control approach that interface the VSC between the PV system and the grid are subjected to the current-voltage based. PV system injects active power to the grid and local load while utility grid monitors the power compensation of load reactive power. The proposed non-linear control strategy is implemented for the VSC to ensure fast error tracking and finite convergence time. The adaptive nature of the proposed non-linear control provides more robustness, less sluggish fault recovery compared to conventional PI control. The comprehensive numerical model is demonstrated in MATLAB script environment with power system disturbances such as faults in the grid. The simulation of proposed system is being carried out in MATLAB/SIMULINK environment to validate the control scheme. The proposed control system regulates the VSC ac side real and reactive power component and the dc side voltage.</span>

Distributed generators using environmentally friendly energy sources such as wind, small water and solar energy have become an important part of the future smart grid/micro grid concept. Design of an autonomous photovoltaic system to study the reaction of solar modules to variable irradiation conditions and their effect on loads. The autonomous system must include a battery storage system to handle non-linear load responses on the AC side. And improve the output power of the photovoltaic system using the MPPT algorithm specially designed to drive linear and non-linear loads on stand-alone systems. And causing the system to respond to varying levels of radiation in the environment and achieve an uninterrupted regulated output of the system. The system examined the behavior of linear and non-linear loads with constant irradiation of 1000 wb / m2 and then modified it to a value between 1000 wb / m2 and 200 wb/m2. The harmonic content in the line voltage increased to 3.34% with a non-linear load by 0.54% with a linear load.
