Abstract
The main function of Custom Power Devices (CPDs) is to provide Quality Electrical Power per the customer’s requirements in the distribution system. For this purpose, CPDs are connected to medium or low-voltage level distribution systems with high- speed power electronic converters/static controllers. In this paper, a CPD called GUPQC consisting of three voltage inverters connected to a common DC-link energy storage capacitor is used in the three-bus distribution system to address power quality issues. The GUPQC simulation model in a single-phase system is simulated in MATLAB. The p-q theory control strategy is used to obtain the required compensating signal to compensate for harmonics of load current at bus-1, and the UVT control strategy is used to generate compensating signal to mitigate the voltage variations during voltage sag / swell at the source bus.
