Abstract: In order to assess the typical LV networks and its low carbon technologies accommodation capability, Western Power Distribution

(WPD) in the UK has initiated one of the Low-Carbon Network (LCN) Projects - Low Voltage Network Templates through funding from the Office of Gas and Electricity Markets (Ofgem). In the project, WPD installs monitors along LV networks at selected LV distribution substations and feeders in South Wales, spanning from Newport to Swansea. These monitors will collect real-time network data, which will be used to develop LV network templates that may be applicable for the entire UK network using statistical approaches. The monitoring will provide detailed information about variable data of the monitored LV substations, PVs and LV feeders. This information will better inform the planning and operation of a smarter network and identify areas where low carbon devices can be connected without triggering large-scale reinforcement. One main aim of the project is to provide visibility of LV network. Additionally, the voltage headroom availability and the stresses brought by low carbon technologies, such as PV installations can be checked and identified.

 

The overall aim of this project is to develop a number of common LV substation templates and classify each substation in other areas in the UK to a template with certain statistical confidence. Based on these templates, the available ?In terms of thermal and voltage over time of day and other network will be quantified as to whether further demand and low carbon technologies can be accommodated into these. The research will interrogate the extensive data using statistical approaches with an aim to inform critical conditions in networks in relation to the low carbon technologies, allowing operators to have targeted interventions as required maintaining their quality of supply. Based on the real-time metered data, the first step of the project is to classify and develop basic load clusters to represent customer classes and seasonal variations One important target of the project is to understand the voltage distribution of both LV feeders and substations are essential part of this project. 

This updated understanding will more accurately visualize the demand profiles of different substations, which helps to understand how networks could accommodate different LCTs penetration levels.
