Dynamic performance improvement of wind power integrated grid using TCP/IP communication network

The increasing penetration of wind power makes the power system more and more complicated, deregulated, and distributed. Thus, the time critical protection needs to be implemented in proper coordination. This requires real time monitoring and controlling of highly non linear modern electric grid, which can be achieved through Wide Area Measurement System (WAMS). Successful implementation of WAMS requires incorporation of fast and reliable modern communication technologies in the power system. In this paper, the system´s dynamic performance is examined with the incorporation of communication technologies. The active power system with 9 MW wind farm is used for the study. WAMS and wind farm communication are based on IEEE standard C37.118.2 and IEC 61400-25 respectively. The different fault scenarios have been simulated and performance is analyzed with the incorporation of communication technologies. The power system has been simulated in MATLAB while communication based simulations have been performed in OPNET. Simulation results clearly show that the incorporation of communication network can avoid wind farm tripping even in severe fault conditions.
