[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 Workshop on Power Electronics and Power Quality Applications (PEPQA) - Manizales, Colombia (2019.5.30-2019.5.31)] 2019 IEEE Workshop on Power Electronics and Power Quality Applications (PEPQA) - Integration of Photovoltaic System in Low Voltage Electrical Network of the Electrical Engineering Building
摘要： The quantification of the impacts of photovoltaic system (PV) integration in the low voltage (LV) power grid is necessary for the historical evaluation of the electrical network with and without PV penetration. This paper presents the study case of the LV electrical network of a university building (Colombia), which has a 9.1 kW PV system. Specifically, the electrical variables monitored were voltages (V), frequency (f), active power (W), voltage distortion (THDv), and harmonics at the Point of Common Coupling (PCC), to determine impairments according to Std. IEEE 1547-2018. PV systems could change the RMS value of voltage at the PCC, therefore, this variable was analysed. Likewise, the frequency was analysed to corroborate the no affectation of the interconnection of the PV system to the electrical network; it is due to the absence of rotational inertia. The solar irradiation information was measured by a pyranometer and the electrical variables by an smart meter, recording the information every 10 minutes for 32 days. The above is an initial step for a comprehensive evaluation of electrical variables with PV generation and future integration of parameters for the resilience evaluation of the electric network.
