In order to solve the problems which are caused by wind power and solar power on-grid, such as power quality, stability, reliability and so on, this paper proposes wind and solar micro-grid including energy storage system(ESS). The micro-grid uses two buses: AC bus and DC bus. Micro-source current is connected to the grid with the same inverter, which can reduce the micro-grid control difficulties. The energy storage system connected to the grid through the inverter could directly absorb energy from the grid. The DC side of the energy storage system using bidirectional DC / DC converter, which can keep the DC side of the battery storage stable.

<p class="Default">In this paper, Vienna rectifier and Z Source Inverter (ZSI) based Wind Power Conversion System (WPCS) has been proposed with less number of switches to provide high quality power to off grid system.  The three phase full bridge converter has six switches for the conversion of AC-DC and also need separate DC-DC boost converter to boost the DC voltage. In the proposed WPCS, three Phase Vienna rectifier has only three switches for the conversion of AC-DC and also it boosts the DC voltage. The ZSI jointly with Vienna rectifier provides higher, boosted AC voltage and high quality power to the off grid system. The ZSI utilizes the shoot-through states to boost the DC link voltage and also, reduces the Electromagnetic Interference (EMI) noise. The combination of Vienna rectifier and Z source inverter shows the good performance which improves the efficiency and reduces Total Harmonic Distortion (THD). The performance of the proposed system is simulated using MATLAB/Simulink software. Simulation and experimental results expose that, this configuration is beneficial with respect to power quality improvement with less number of switches compared to a conventional converter.</p>
