A grid tied photovoltaic (PV) power conversion topology is presented in this study with a novel scheme of re-synchronisation to the grid. This scheme serves the purpose of supplying continuous power to the load along with feeding power to the grid. The control approach helps in mitigation of harmonics and improving the power quality while extracting the optimum power from the PV array. Depending on...
The ever mounting demand of electrical energy and the keen scarcity of conventional energy sources leads to the burgeon of distributed generation (DG) system. The main abstruse is the harmonization of the DG to the utility grid. Generally current regulated PWM voltage-source inverters (VSI) are used for synchronizing the utility grid with DG source in order to meet the following objectives: 1) To...
This paper addresses the issue of the evaluation of how modern and restructured Transmission and Distribution (T&D) infrastructures help accomplish the so-called EU 2020 targets, in terms of efficiency increase, CO2 reduction and a wider employ of renewable energy resources. A methodology is proposed in order to quantify the possible environmental benefits as well as the power quality improvement...
Injection of the wind power into an electric grid affects the power quality. The performance of the wind turbine and thereby power quality are determined on the basis of measurements and the norms followed according to the guideline specified in International Electro-technical Commission standard, IEC-61400. The influence of the wind turbine in the grid system concerning the power quality measurements...
The increasing interest to utilise wind energy as a power source prompted more researches to be dedicated to the efficient integration of this power source into the current grid. In this paper, one avenue to achieve this efficient utilisation, through the use of current- controlled voltage source inverter (CC-VSI) integrated with a permanent magnet synchronous generator (PMSG) wind energy conversion...
