Simple digital current control strategy for single-phase grid-connected converters
This study proposes a simple digital current control technique for single-phase grid-connected voltage source converters. Unlike conventional strategies, the proposed method does not require any proportional-integral or proportional...
Adaptive Predictive-DPC for a Grid Connected Low-Cost PV Generator
deadbeat-DPC scheme for the grid connected PWM-VSC which utilizes the adaptive observer in its structure is proposed. States and input disturbances are estimated by using full order adaptive observer in next sampling period and then by using the system...
A Novel Control Technique for Single-Phase Grid-Connected Inverters
A synchronous reference frame controller with a multi-resonant harmonic compensator for single-phase gridconnected inverters is proposed in this paper. The essence of the proposed control strategy is to use a synchronous ...
Low computational burden grid voltage estimation for grid connected voltage source converter-based power applications
This study presents a simple and efficient approach for grid voltage estimation based on the converter equations in the stationary reference frame. The proposed technique is adopted for the sensorless operation of the ...
An optimal power flow control method for grid-connected inverters
Most of the modern renewable energy technologies generate DC electric power, which is incompatible with AC grids. In order to control the power flow from DC bus of such generating units to AC grids, grid-connected inverters are essential. This paper...
Investigation of the possibility of removing the grid side inductance from the LLCL filter circuit
It has been shown in the literature that in the grid connected converters, which uses trap based filters, like LLCL, the grid side inductance and therefore the filter size is effectively reduced. This paper with the goal of further reducing...
Economic analysis and first results of recent feed in tariff scheme for grid connected photovoltaic systems in Iran
This paper discusses the new feed in tariff plan and its effect on grid connected photovoltaic systems in Iran. The well legislated new scheme in 2015 and its remarks, is explained in details. The economic perspective is evaluated through...
