[IEEE 2018 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC) - Kota Kinabalu, Malaysia (2018.10.7-2018.10.10)] 2018 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC) - Determination of Penetration Limit of Solar Distributed Generation (DG) Considering Multiple Bus Integration
摘要： 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.

[IEEE 2019 IEEE PES Innovative Smart Grid Technologies Conference - Latin America (ISGT Latin America) - Gramado, Brazil (2019.9.15-2019.9.18)] 2019 IEEE PES Innovative Smart Grid Technologies Conference - Latin America (ISGT Latin America) - Local volt/VAr Control in Distribution Networks with Photovoltaic Generators
摘要： The Distributed Generation (DG) is characterized by the production of electricity connected to the distribution network or to the local network consumers, using renewable or non-renewable resources, technology. Excessive use of DG systems connected to the distribution network may regulation, compromising the system control and protection devices and the reliability, due to the voltage increase in the DG connection point. In this context, this work presents an analysis of frequency that performs a photovoltaic data transmission interface with an electric grid, as a new possibility of voltage control and reactive power (volt/VAr) in sets with the usual instruments of control used in electricity distribution networks. The analysis consists of performing the volt/VAr control from the frequency inverters in low or medium voltage networks, where the inverter assists in voltage regulation through the insertion and/or absorption of reactive power in the distribution system. In order to demonstrate the proposed methodology application, tests were performed on a standard IEEE 13 node in the OpenDSS? software, comparing the voltage profiles and position adjustment of voltage control for a given DG penetration index and different inverter operating conditions.
