Cascading Failures Assessment in Renewable Integrated Power Grids Under Multiple Faults Contingencies

Cascading overload failures occurred in power systems due to higher penetration of renewable energy resources (RERs), which causes uncertainty a grid. To overcome these cascading failures, proper assessment the form load flow balancing and transients stability is required integrated grids (RIPGs). This problem becomes more critical occurrence multiple intervals faults interconnected RIPGs, tripping several RERs. Due outages various transmission lines, lead system failures. tackle this problem, hybrid probabilistic modeling proposed paper for an RIPGs. For flow, smart node network topology utilized along with integrating unified controller (UPFC), while instabilities are assessed through UPFC alone. Contrary previously algorithms, only suitable compensate case single interval fault, work supported by under not fault but also severe RIPGs that will failure outages. Simulation results verify our algorithm achieved near optimal performance outperforming existing methodologies, confined mitigate effect fails address faults, leads These simulation validated industrial study performed on western Denmark show superiority algorithm.
