It is frequently admitted that the rate of photo voltaic (PV) peak power must not exceed 20% to 30% of the maximum power consumed on a given LV feeder. As a result, the PV hosting capacity remains quite low, or the DSO takes the risk of voltage issue if he decides to exceed. RESA, the Belgian DSO and Odit-e, a French startup have tested a new way to at least double the PV hosting capacity of network feeders. An experimentation was made in an area already overequipped with PV and subject to voltage issues. Results show that it has been possible to tackle existing voltage issues efficiently and to identify a significant additional hosting capacity.
The topology is the corner stone of the analysis of the low voltage grid. However, the current information is often a not-up-to-date GIS storing the bulk of information about the Distribution System Operator’s assets’ characteristics and location. Its content is not complete and accurate enough to perform a modelling of the low voltage network.
Providing the meter – phase – feeder – transformer connection, the topology would pave the way to a greater operation.
This lack can be filled thanks to the analysis of smart meters data. The paper presents the methods available to retrieve the topology, their pros and cons and evaluates a new algorithm using the voltage curve of every meter in a defined geographical area in order to find it out.
