A Novel Approach for Distributed Generation in Hybrid Power Systems using PMU Control Networks

Abstract: Distribution Generation (DG) is a renewable energy in small scale near to the load in a distribution system. Installation of DG in power system can reduce the power loss and improve the voltage profile. Thus the DG will serve as an interconnecting network between the Generation and Distribution Units of an Off-Grid Power system. In this project we introduced a novel approach for DG design, modeling and implementation using a widely accepted, universally trusted and highly efficient Phasor Measurement Techniques. The proposed algorithm constructs the PMU Control Network to act as a DG Unit between the generation and the distribution units of the Distributed Generation Off-Grid Hybrid Power System (DG-HPS)s. The PMU Control Network not only serves as DG Unit, but also detects, locates and isolates all types of faults that cause heavy power loss and severe damage to the circuitry in both generation and distribution units of the Off-Grid Power System (OGPS)s. These PMU based DG Units will bridge the generation and distribution units and test on several cases, to find the optimal sizing and location of DG in distributed network to decrease the power loss and to improve the voltage profile. This method has been tested on the standard IEEE-9 bus distribution network using MATLAB R2012a software. The result shows that the proposed DG Units are working well and their performance is well sufficient to meet present application demands of the Off-Grid power systems.
