Abstract: “This paper deals with soft logic rather than hard logic. Matlab based hybrid model of wind solar and thermal energy generation is developed. Fuzzy logic based controller takes decision As how much non conventional power can be injecting to the conventional system during fault condition so that the rotor angle variation limits and transient stability of system is improved .Large interconnected power system events need careful co-ordination of logical events for complex or catastrophic situations”
