The probability of a cascading failure in the power grid is small when β and γ are both larger than the thresholds β? and γ?. Find out the thresholds β? and γ? as a guide for the engineers to choose the proper tolerance parameters in order to ensure the stability and low cost of power grid. * Outline Introduction Swarm Dynamics Consensus Protocol Escape Panic Locust Swarming Evolution of Cooperation Cascading Failure in Indian Power Grid Conclusions Conclusions
