Achieving Economic Operation and Secondary Frequency Regulation Simultaneously Through Feedback Control [PDF]

IEEE Transactions on Power Systems, 2016
This article presents an exciting finding for the power industry: the parameters of secondary frequency control based on integral or proportional integral control can be tuned to achieve economic operation and frequency regulation simultaneously. We show that if the power imbalance is represented by frequency deviation, an iterative dual decomposition ...
