Challenges to voltage regulation in distribution networks from large scale battery energy storage connections
IET Singapore Network Power and Energy Section Networking Seminar
About
Distribution Network Operators (DNOs) own and operate electricity distribution networks in the UK from low voltage up to and including 132 kV. The number of requests to connect large-scale Battery Energy Storage Systems (BESS) to the distribution network is growing. This has accelerated, given BESS can provide a growing number of grid services, including frequency response services.
BESS can change their power input or output instantaneously and frequently. For large-scale BESS, generally sized between 10 MW and 100 MW, this presents a number of challenges to DNOs in terms of their assessment and keeping network voltages within acceptable limits.
This presentation sets out these challenges, particularly in the context of complying with voltage regulation requirements in the Distribution Code and ENA Engineering Recommendation P28, and how guidance on assessing BESS connections is changing to strike the right balance between reducing barriers to connecting BESS whilst minimizing risks to the operation of the distribution network.
