Load Flow Studies
What is the purpose of a load flow study? Load flow studies are one of the most fundamental study types carried out as part of system analysis; but they are often ignored by companies as they are seen as a bit wooly and non-essential. However, they are actually very useful and tell the designer a […]
Battery Energy Storage Systems – Dynamic Containment & P28/2
Grid Connected Battery Energy Storage Systems – Dynamic Containment Part 1: Introduction This post is a follow on to our previous post, which discussed battery energy storage in general, and its application to power arbitrage.In this post we talk about battery storage & P28/2, which is the UK standard on voltage disturbance. This topic is […]

The old G5/4 standard was rather outdated and has been due for an update for a while. The new G5/5 harmonics standard is much more comprehensive, […]
ENA G99 – Type C and D Plants – System Studies Compliance
ENA G99 – Type C and D Plants and Studies Overview This is a follow up post to my earlier one on G99 system studies. This time the post focuses on Type C and D plants (>10MW), which are a lot more challenging. The difference between Type C and D is fairly minor from a […]
ENA G99 – Type B Plants – System Studies Compliance
ENA G99 Type B Plant and Studies Overview ENA G99 has been with us for just over a year now and I think its fair to say it has been a bit of a rocky road so far. We are already on Amendment 6 of G99, as various issues and clarifications keeping coming up and […]
