Abstract 

The data provided here correspond to the TPWRS paper presenting a novel  filter design procedure to optimally split the Frequency Regulation (FR) signal between conventional and fast regulating Energy Storage System (ESS) assets, considering typical Communication Delays (CDs).  The filter is then integrated into a previously validated FR model of the Ontario Power System (OPS) including Battery and Flywheel ESSs, which is used to analyze the impact of these ESSs, CDs, and limited regulation capacity in the FR process in a real system.  The proposed methodology to split the FR signal is also compared with the existing FR process, with the results showing that the proposed  filter design and signal splitting strategy can improve the FR process performance significantly, in terms of reducing the Area Control Error (ACE) signal, and thus reduce the need for regulation capacity.

Instructions: 

The *.mat files attached include the state-space representation of the Generalized plant, with and without delays, in the paper "Regulation Signal Design and Fast Frequency Control with Energy Storage Systems". By following the instructions in Section III.A of the paper, the state-space matrices of the Generalized Plant GP(z) can be use to generate the controller F(z) proposed in the paper.
