Versions Notes Abstract The power system is going through a change in its very foundations. More and more power converters are being integrated into the electric grid to interface renewable energy resources and in high-voltage direct-current (HVDC) transmission systems. This article presents a discus...
frequency variations while the transmission lines are modeled as single PI sections.The generator G1, connected to bus 39, represents the aggregation of a large number of generators of the power system of New York that is interconnected with the New-England power system and represented in detail...

Introduction The insulation materials used in the HVDC transformers correspond to the insulation materials in the conventionally used transformers. Mainly mineral oil-based insulating oils are used...
However, several instability issues arising from uneven large power generation requires TSOs (transmission system operators) to complement the grid structure [1]. Moreover, based on References [2,3,4], grid interconnection is emerging as an effective alternative for solving stability problems. For ...
