Determination of penetration limit of solar distributed generation (DG) considering multiple bus integration

Abstract

© 2018 IEEE. Solar distributed generation (DG) integrated into the distribution system has contributed significant effects such as reduced power losses and improved voltage profile. The reliability and power quality of the technology may be affected at high penetration that may result to high voltage fluctuations and reverse power flow. Thus, the maximum allowable penetration level of solar DG must be determined. By using genetic algorithm as an approach, this study determines the penetration limit of solar DG in the network considering multiple bus integration. Simulations were implemented in IEEE 37-bus test system utilizing the Component Object Model (COM) interface of MATLAB and OpenDSS. Results showed that considering the penetration limit of solar DG resulted to significant improvements in power losses and voltage profile. Moreover, the maximum allowable limit of the DG installed to 18 different buses showed the highest reduction of power losses and the lowest average total voltage deviation.
