The control systems in current and future power systems need reliable real-time information transmission. Internet Protocol (IP) based communication systems for wide-area frequency stability predictive control systems are proposed in this paper. The key technologies, such as network topology, communication protocols, and communication modes are studied. The frequency stability predictive control algorithm need the wide-area measurements sampled in plants and substations to be transmitted to a main control node and load shedding commands to be sent to substations from the main control node. A modified IEEE 50-generator test system equipped with the proposed wide-area frequency stability predictive control is established and simulated using the electric power and communication synchronizing simulator (EPOCHS). PSS/E is combined the Network Simulator 2 (NS2) in the EPOCHS simulation environment. The simulation results show the effectiveness of the proposed communication system.
