AbstractIn this paper, the concept of analog filter circuit is used for designing of wide area damping controller (WADC) in power system. The designed continuous mode filter based WADC is robust enough to deal with the problem of imperfect communication medium, which include process noise, measurement noise and signal latency in wide area remote signal. Residue method is used for the selection of wide area control signal and controller location. Modelling of imperfect communication network is done using Pade approximation and by inserting Gaussian random noise. The effectiveness of filter based WADC as a power system stability agent is assessed in the frequency domain using two typical test power systems and via appropriate time domain simulations based upon the non-linear model on MATLAB/Simulink software platform.

The cyber-physical nature of electric power systems has increased immensely over the last decades, with advanced communication infrastructure paving the way. It is now possible to design wide-area controllers, relying on remote monitor and control of devices, that can tackle power system stability problems more effectively than local controllers. However, their performance and security relies extensively on the communication infrastructure and can make power systems vulnerable to disturbances emerging on the cyber side of the system. In this paper, we investigate the effect of communication delays on the performance and security of wide-area damping controllers (WADC) designed to stabilise oscillatory modes in a Cyber-Physical Power System (CPPS). We propose a rule-based control strategy that combines wide-area and traditional local stabilising controllers to increase the performance and maintain the security of CPPS. The proposed strategy is validated on a reduced CPPS equivalent model of Great-Britain (GB).
