Ok, by “stability”, I am meaning that if you have a short circuit, loss of load, or loss of generation, how long does the grid remain stable without collapsing / shedding customers. This is usually measured in seconds, and can range from a second or less for small systems to tens of seconds for a large power system. This “inertia” buys the power system operators time to correct the initial fault that has upset the balance between load and generation.
Thanks - I think I understand now.
So if the system has only a small amount of inertia, would the battery system cutting in quickly - either supplying more power or absorbing extra power - likely help to extend the period available to adjust conventional generation? Presumably the less the difference between generated and consumed power the longer the spinning bits will remain within an acceptable speed/frequency.
