To remove these barriers\, speed up connection times\, and reduce costs\, it is crucial for distribution comp anies to increase the PV hosting capacity of their low and medium voltage networks. Adequately exploiting the capabilities of existing and new netwo rk assets\, PV inverters and batteries will be key.\n\nThis talk presents the benefits from adopting non-traditional solutions such as strict Volt-W att and Volt-Var PV inverter settings\, OLTC-fitted LV transformers\, Batt ery Energy Storage (BES) systems with Off-the-Shelf (OTS) and smarter cont rollers in combination with traditional solutions\, and dynamic voltage ta rget at zone substation OLTC aiming at increasing the solar PV hosting cap acity of PV-rich distribution networks. The study was carried out as part of the project "[Advanced Planning of PV-Rich Distribution Networks](https ://www.google.com/url?q=https%3A%2F%2Farena.gov.au%2Fprojects%2Fadvanced-p lanning-of-pv-rich-distribution-networks-study%2F&sa=D&sntz=1&usg=AFQjCNGY UbcyFuHqv1BiBY7nJ-HOQrVVZQ)" funded by the Australian Renewable Energy Age ncy (ARENA) and the distribution company AusNet Services. It includes the results of one the most advanced\, highly-granular\, detailed studies perf ormed on multiple fully-modelled 22kV feeders (i.e.\, urban and rural\, in cluding pseudo low voltage networks) from Victoria\, Australia considering time-series seasonal analyses and growing penetrations of solar PV. Findi ngs show that the adaptive control of OLTC-fitted LV transformers can effe ctively manage voltages and\, in combination with network augmentation\, c an increase hosting capacity to 100%. OTS BES systems do not change the ho sting capacity as they are unable to reduce peak PV exports (they become f ull early in the day). However\, advanced BES controllers that do reduce e xports (such as the investigated Network Smart controller)\, could help in crease hosting capacity to 100% without much need for network augmentation . The strict Volt-Watt and Volt-Var settings\, as well as the dynamic volt age target at the primary substation OLTC\, are effective in mitigating vo ltage problems. However\, asset congestion can still occur\, limiting thei r ability to significantly increase hosting capacity.\n\nCo-sponsored by: Jahangir Hossain\n\nSpeaker(s): Prof. Nando Ochoa\, \n\nVirtual: https://e vents.vtools.ieee.org/m/278969 LOCATION:Virtual: https://events.vtools.ieee.org/m/278969 ORGANIZER:jahangir.hossain@uts.edu.au SEQUENCE:8 SUMMARY:Solar PV Hosting Capacity of Distribution Networks: The Benefits of Non-Traditional Solutions URL;VALUE=URI:https://events.vtools.ieee.org/m/278969 X-ALT-DESC:Description: <br /><p class="CDt4Ke zfr3Q" dir="ltr">Electricity distribution companies in many countries around the world are finding it challenging to allow residential customers to continue to install photovol taic (PV) systems due to the potential technical impacts resulting from hi gh penetrations.
