Customer Led Network Revolution — Integrating renewable energy into LV networks using energy storage

Integrating renewable energy into LV networks brings a number of challenges to existing distribution networks, particularly steady-state voltage rise and in some cases voltage unbalance. Electrical Energy Storage (EES) systems can play an essential role in facilitating renewable energy integration by mitigating voltage rise problems and unbalanced issues. As part of the Customer Led Network Revolution (CLNR) smart grid project, this paper describes research relating to the voltage rise issues arising from large-scale PV integration and presents a solution using EES, based on data analysis from a field trial network, PSCAD simulation and laboratory emulation.
