Optimal FRT compliance of offshore wind power plants in VSC-HVDC connection based on genetic algorithms

摘要: This paper proposes a new methodology for the optimal compliance of offshore wind power plants in VSCHVDC grid connection with typical Fault-Ride-Through (FRT) requirements. Unlike traditional chopper based solution, an improved AC voltage drop FRT strategy, which is communication free and ensures robust faulted dynamic response proposed to achieve compliance. The calculation best parameters enable successful formulated as optimization problem. objective function aims at minimizing electrical stresses imposed HVDC system during post-FRT period, while simultaneously ensuring plants. tackled on iterative procedure that combines EMT-type modelling VSC-HVDC connected type 4 plants, genetic algorithm search process. Numerical results point-to-point extended three terminal case are demonstrated.
