National Grid has a statutory obligation to manage the frequency between pre-defined limits. If there isn't effective frequency response available then the likelihood of a frequency excursion outside of statutory limits will increase. To this end, National Grid are going to trial enhanced frequency response as a mechanism to assist with frequency control in the light of reducing system inertia. This...
This paper describes the operational experience gained from running example Sodium Nickel based batteries on the 11kV UK Distribution Network over the period of a year. The experience gained informs Network Operators on how the batteries behave under different operating conditions including frequency response, voltage control and peak load lopping and discusses availability issues through the presentation...
This paper is part of a project which aims to research the opportunities for the re-use of batteries after their primary use in low and ultra low carbon vehicles on the electricity grid system. One potential revenue stream is to provide primary/secondary/high frequency response to National Grid through market mechanisms via DNO's or Energy service providers. Some commercial battery energy storage...
