Voltage source converter control under unbalanced grid voltage conditions
2017 XXVI International Conference on Information, Communication and Automation Technologies (ICAT), 2017This paper proposes a novel control method for voltage source converter (VSC) connected to grid under unbalanced voltage conditions. The method is based on utilizing the full control capabilities of the switching converter. The proposed method makes the voltage source inverter (VSI) supply the voltages according to the requirements of the load and/or ...

An Improved Control of D-STATCOM under Unbalanced Grid and Load Conditions
2019 IEEE 28th International Symposium on Industrial Electronics (ISIE), 2019A novel and simple control method is proposed in this paper to improve the operation performance of the distribution static synchronous compensator (D-STATCOM) under unbalanced operating condition. The functional block for extracting positive and negative sequence components is eventually avoided by employing dual current regulators in positive- and ...

Power Control of Grid-Connected Converters Under Unbalanced Voltage Conditions
IEEE Transactions on Industrial Electronics, 2015This paper presents a grid current control technique on the power converter level. The submitted analysis deals with a control method of positive and negative current sequences in a grid-connected converter during voltage sags. The control method should assure the proper exchange of active and reactive powers without power ripple, the mitigation of ...

Fast Delayed Signal Cancellation based PLL for unbalanced grid conditions
2018 IEEE International Conference on Automation/XXIII Congress of the Chilean Association of Automatic Control (ICA-ACCA), 2018Frequency identification is one of the most critical issues for grid-connected power converters, especially when the grid is unbalanced or distorted. Therefore, this paper proposes a novel frequency estimator with fast convergence for balance and unbalanced grid-voltage faults. The proposed algorithm is based on a Phase Locked Loop (PLL), enhanced with
