For grid-connected photovoltaic (PV) system, monitoring is considered as a crucial aspect for observing the stability and performance of the system. The simplest method is to have the data collected and transmitted across data cables. Due to the cost and technical limitations of the data cable, the monitoring station needs to be located reasonably close to the monitored plant. Apart being incon...

Performance, quality and reliability issues are becoming more and more important for the emerging photovoltaic markets worldwide. The purpose of this work is comparing and presenting operational performance results of grid-connected PV systems, as collected and elaborated for Task 2 of the Photovoltaic Power Systems Programme (PVPS) of the International Energy Agency (IEA). The data analysed he...

Grid-connected photovoltaic (PV) systems are designed to provide energy the grid. This transfer must fulfil some requirements such as system stability, power quality and reliability. Thus, aim of this work is design control a grid-connected PV via wireless guarantee correct operation system. It crucial monitor supervise and/or detect faults in real time remote way. To do that, DC/DC converter D...

MODULARIZED MULTILEVEL AND Z-SOURCE POWER CONVERTER AS RENEWABLE ENERGY INTERFACE FOR VEHICLE AND GRID-CONNECTED APPLICATIONS By Dong Cao Due the energy crisis and increased oil price, renewable energy sources such as photovoltaic panel, wind turbine, or thermoelectric generation module, are used more and more widely for vehicle and grid-connected applications. However, the output of these rene...

Recently, the regulation of photovoltaic inverters, effectively under imbalanced voltages on grid, has been crucial for operation grid-connected solar systems. In this regard, determining output current reference is an integral aspect managing a inverter with unbalanced voltage. Based evaluations Instantaneous Active-reactive Control (IARC), Positive Negative Sequence (PNSC), Balanced (BPSC), a...

This paper presents a robust multi-input multi-output (MIMO) state-feedback control scheme for photovoltaic (PV) inverter connected to weak grid. For grid, the point of common coupling (PCC) voltage is very sensitive power disturbances and it dynamically coupled PLL dynamics. So far, most methods do not take into accounts these couplings. Therefore, in this paper, MIMO controller was designed t...
