NIE networks low voltage optimisation through active network management

This paper presents findings from trials investigating the implementation of Low Voltage Active Network Management (LV ANM) schemes within Northern Ireland Electricity Networks' licence area. The study evaluates the impact of strategic network reconfiguration, including the closure of normally open positions and the establishment of meshed networks, on voltage and power dynamics. Results demonstrate notable improvements in voltage levels and daily peak power reduction throughout the tested LV networks, addressing issues commonly associated with increased renewable energy integration. Moreover, positive changes in active power within the LV network highlight enhanced visibility, control, and optimisation capabilities afforded by LV ANM. Reconfiguration of feeder networks facilitated more efficient utilisation of available capacity, thereby reducing peak loading of assets. Additionally, the implementation of LV ANM could contribute to deferring network reinforcement costs, showcasing the economic benefits of this approach. These findings underscore the case for integration of LV ANM into regular operations, offering tangible benefits for modern power distribution systems in terms of reliability, efficiency, and sustainability.
