ItemAdvanced Planning of PV-Rich Distribution Networks - Deliverable 3: Traditional Solutions(Department of Electrical and Electronic Engineering, The University of Melbourne, 2020)This document investigates the adoption of traditional solutions such as change of off-load and on-load tap changer positions and/or network augmentation to increase the hosting capacity of PV-rich distribution networks considering the new Victorian Volt-Watt and Volt-var settings which mandates that both power quality response modes are enabled. Studies are performed on four fully modelled and significantly different HV feeders (i.e., urban and rural) considering time-series seasonal analyses with growing penetrations of solar PV. Findings show that enabling both Volt-Watt and Volt-var functions with the Victorian settings provides significant benefits to both DNSPs and customers. Voltage rise issues and curtailment are dramatically reduced, making it possible to host 20% of customers without the need for other solutions. Adopting traditional solutions can help increase the solar PV hosting capacity to 40% (excluding HV feeders with long SWER lines). However, beyond 40%, traditional solutions were found to have limited effectiveness in mitigating network issues.

ItemAdvanced Planning of PV-Rich Distribution Networks - Deliverable 2: Innovative Analytical Techniques(Department of Electrical and Electronic Engineering, The University of Melbourne, 2019-10-22)This document presents a smart meter-driven analytical technique proposed by The University of Melbourne to estimate PV hosting capacity in distribution networks. Two significantly different HV feeders, urban and rural, are modelled in detail with growing PV penetrations in a horizon of 5 years to create a large realistic smart meter data set. The analytical technique is then applied to this data set for different PV penetrations. The findings show that the proposed analytical technique provides adequate estimations of PV hosting capacity, making it a faster and simpler alternative to model-based approaches.

ItemAdvanced Planning of PV-Rich Distribution Networks - Deliverable 1: HV-LV modelling of selected HV feeders(Department of Electrical and Electronic Engineering, The University of Melbourne, 2019-06-10)This document first presents the process adopted by The University of Melbourne in collaboration with AusNet Services to select the HV feeders that will be modelled and used throughout the project. Then, the selected HV feeders are fully modelled along with their corresponding LV networks using the software OpenDSS.

ItemDeliverable 1.1 Literature review and initial modelling(Electricity of France (EDF), 2014)This report corresponds to Deliverable 1.1 “Literature review and initial modelling” part of the Work Package 1 “On-load tap changing LV transformers” of the project “Active Management of LV Networks” jointly funded by EDF and EPSRC. The Active Management of LV Networks project has been established in order to investigate the effect of applying active management techniques to increase the ability of low voltage networks to accommodate a higher number of low carbon technologies, in particular photovoltaic (PV) systems and electric vehicles (EV). The project will focus on the utilization of on-load tap changing transformers and coordinated control of low carbon technologies themselves and other technologies to control voltages and congestion in the network. This document presents the initial modelling aspects of LV networks, including the on-load tap changer (OLTC), as well as load and PV profiles. In addition, a control logic for the OLTC is proposed and its performance assessed considering different PV penetrations and also different monitoring approaches. These models provide a solid foundation for the LV network simulations to be carried out throughout the project as well as the further development of control logic. Some parameters which are UK specific will be adjusted to the French standards when appropriate.
