Therefore, the conclusions drawn in these studies are often specific to the study cases, limiting their applicability for generalization. This paper proposes a methodology that can generate a multitude of network topologies that have statistically similar characteristics to a selected cohort of existing networks. Furthermore, a stochastic evaluation based on the Monte Carlo technique is utilized to analyse the impacts of solar PV on generated LVDN models. A case study was conducted on ten networks that were generated statistically similar to existing urban networks to allow for a more generalized study. A total of 1000 Monte Carlo simulations for each network was carried out to accurately identify the most representative parameters that reflect the voltage rise and voltage unbalance in the considered LVDN cohort. Two parameters, namely: the momentum of the PV capacity and the mean absolute deviation, were identified from the case studies as the most representative parameters to analyse the impact of voltage rise and voltage unbalance factor. Thereafter a generalized framework based on these two parameters was derived to determine the impact of PV connections to the selected cohort of networks. This framework facilitates an efficient process for the utility supplier to determine the impact of incorporating new PV connections without the need for extensive studies. � 2020 Elsevier Ltd Final 2023-05-29T08:07:26Z 2023-05-29T08:07:26Z 2020 Article 10.1016/j.ijepes.2020.106058 2-s2.0-85083561346 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85083561346&doi=10.1016%2fj.ijepes.2020.106058&partnerID=40&md5=12f03fe9f1cc7bb7023651045f80578b https://irepository.uniten.edu.my/handle/123456789/25225 121 106058 Elsevier Ltd Scopus |
