| dc.title | Probabilistic power flow analysis of active distribution networks | en_US |
| dcterms.abstract | As increased number of distributed photovoltaic (PV) units are integrated into distribution network (DN) will cause voltage deviation and violation for its intermittent property, system operators need to consider the integration and security of the DN, and the rationally improve the integration capacity of PV power need to pay attention to. | en_US |
| dcterms.abstract | The constrains of static security index and which factor will fluctuate the voltage is considered, a method named max integrated optimal capacity model of PV units is put forward. | en_US |
| dcterms.abstract | In addition, this dissertation analyzes the influence of vary-size PV grid capacity and the access position, considering deviation of the voltage and the probabilistic of the target valuables exceed the limitations. | en_US |
| dcterms.abstract | Moreover, Institute of Electrical and Electronics Engineers (IEEE) standard node systems are used to analyze accessible capacity maximization problems. | en_US |
| dcterms.abstract | A MATLAB R2019b planform is applied for the evaluation and processing for this proposed dissertation. By the processing of IEEE 4-node system and IEEE 13-node system, both integration capacity range and the max PV power integrated capacity at every node is processed and dealing. And to limit the voltage deviation within limit, 3-phase shunt capacitors are used to tune the voltage level performance. | en_US |
| dcterms.abstract | The result shows that the PDF and CDF curve of the voltage or current angle and amplitude, and their fluctuations and violation can be easily analyzed after increasing the PV capacity and adding the capacitor banks. | en_US |
| dcterms.abstract | Finally, the grid-connected spots affect the PV penetration level and power loss a lot, indicating an impact of directional load flow of PV. | en_US |
