Control of Active Power Sharing in DG integrated Parallel DSTATCOM

P.V.V. Satyanarayana,P. V. Ramana Rao

Power Quality is a closeness measure of practical power system to ideal power system. Disturbances in power system cause immense damage to the power network and power quality is a study taken up by power engineers to regulate power system. Consequent to power electronic technology for the development of Custom power devices (CPD) to regulate the power system disturbances, DSTATCOM, a renowned CPD for harmonic compensation in power distribution system, has emerged. Disadvantages of fossil fuels led to the development of Distributed Generation (DG). This paper presents a topology of common DC-Link fed parallel DSTATCOM which combines the features of power quality improvement and active power injection. This topology avoids the use of separate VSIs for power quality improvement and DG integration. A new control methodology is presented for controlling the active power sharing between two VSIs of parallel DSTATCOM. The proposed model is developed using MATLAB/SIMULINK software and the results are analyzed.
