We just submitted our paper “Performance Limitations of Distributed Integral Control in Power Networks Under Noisy Measurements” to the 2018 ACC.
This paper extends the analyses in my previous work on the performance of distributed PI-control in power networks, and considers how noisy frequency measurements impact performance. It turns out, that measurement noise may have a very large negative impact on performance. We show how this impact depends on the tuning and design of the distributed-averaging filter that aligns the controllers’ integral states.
This work was done together with Hendrik Flamme, who was an M.Sc. student interning in our lab earlier this year.
