Nowadays, LCL filters utilization to suppress the grid-connected inverter switching harmonics is expanding and various methods such as capacitor current active damping scheme could be investigated to damp out these harmonics. However, the computational delays including control system, and PWM switching delays have significant effect on damping system stability. In most of LCL filter parameter d...
In this paper, a detailed mathematical model of a grid-connected micro-grid including wind-turbine, photo voltaic cells, CHP and Fuel Cell with respective uncertainties in electrical loads, thermal loads, PV and wind outputs are presented. Moreover, the effects of the considered uncertainties on the micro-grid’s operation cost are modeled as risk and this risk is reduced using Monte-Carlo...
A novel current source multilevel inverter is introduced in this paper which is an appropriate alternative to be employed for low/medium power applications. the proposed converter is formed basic modules which paralleling these modules increse output current levels and improve quality of injected current to load or grid. in order to validate advantages of proposed converter versus the several m...
although lcl filters are used widely in the grid connected inverters to reduce high-orderharmonics, such a system increases system order and therefore sustainable design of closed-loopcontroller system will be complicated. recently, the single-loop control strategy has beensuggested for l or lc filter based grid-connected inverters. however, the use of single-loopcontrol directly in lcl filter-...
