This paper proposes new control strategy for grid connected three-phase Voltage Source Converter (VSC). The strategy is designed to overcome problems of conventional voltage oriented VSC control operating under distorted grid voltage. Proposed control strategy cancels the influence of characteristic distribution grid voltage harmonics, and injects close to sinusoidal current to the grid, with permitted...
A novel control scheme of the grid-connected voltage source converter (VSC) under harmonically distorted grid voltage conditions is proposed in the paper. A dynamic mathematical model of a PWM converter based on the grid voltage-oriented fundamental frequency synchronous coordinate frame under harmonically distorted grid voltage condition is derived. According to the instantaneous active and reactive...
In this paper a power electronic interface (PEI) that integrates up to two renewable energy sources is presented. The generation of the different distributed sources is controlled through the DC link terminal voltage and the AC terminal voltage of the voltage source converter (VSC). The renewable source can be controlled to supply electricity to the local load and export the exceeding energy to the...
In this paper a power electronic interface (PEI) to integrate up to two renewable energy sources is presented. Through the control of the DC link terminal voltage and the AC terminal voltage of the voltage source converter (VSC) the generation of the different distributed sources can be adapted to the grid, supplying the local load and exporting energy to the grid. The system was analyzed under distorted...
