| Popis: | 31st European Photovoltaic Solar Energy Conference and Exhibition; 3102-3106 The distributed nature of the solar resource indicates that photovoltaic (PV) generation is particularly suited for distributed generation (DG) and it will be among the major driving forces towards a paradigm shift of the traditional distribution segment. This research proposes an analysis framework to guide engineers in the assessment of PV power sources impacts when connected to distribution networks, to assist in network access studies and to help utilities on defining adequate grid codes. A probabilistic approach based on a probabilistic load flow model suited for radial distribution systems analysis is implemented. Uncertainties about load and generation parameters, which are relevant in order to assess operational and planning issues, can be represented, mainly, uncertainty about system active and reactive power loads and due to PV generation. In this paper, active power losses, voltage unbalance and the influence of R/X parameter are investigated. Simulation results obtained indicate that the approach adopted gives a consistent framework for evaluating the different operation scenarios that arise on practice. |
