Cyber security solution for wide area measurement systems in wind connected electric grid

Wind energy is considered as the most promising, cost-effective, and green energy among the prevailing renewable energy sources. The integration of wind power with conservative electric grid poses challenges related to power system dynamics due to its intermittent nature. This necessitates the real time monitoring of electric grid, which can be achieved through Wide Area Measurement Systems (WAMS). The real time control operations require cost effective, high speed, and secure communication infrastructure. Modern electric grid has become the integration of WAMS, communication systems, and information technology infrastructure hence, cyber security issue arises. New cyber security challenges needs to be addressed adequately. This paper proposes the cyber security architecture for electrical grid and the functioning of various parts of the architecture has been discussed. We have simulated the proposed architecture to check the impact on latency, due to the introduction of IPSec for securing data while, transmitted over communication channel.
