On the Numerical Accuracy of Electromagnetic Transient Simulation With Power Electronics [PDF]
IEEE Transactions on Power Delivery, 2018 This paper investigates the numerical accuracy of currently employed methods for electromagnetic transient simulation with power electronics. Existing tools often employ the second-order accurate trapezoidal method for numerical integration. However, solution techniques employed to facilitate ideal power-electronic switches do not always preserve this ...

Improved adaptive regularization for simulated annealing inversion of Transient Electromagnetic
Scientific Reports, 2023 Abstract Geophysical inversion usually involves ill-posed problems. Regularization is the most commonly used method to mitigate the ill-posedness faced in geophysical inversions. Adaptive regularization methods have been more widely used in linearized inversion than in stochastic inversion methods.

A relaxation scheme to combine phasor-mode and electromagnetic transients simulations [PDF]
2014 Power Systems Computation Conference, 2014 This paper deals with a new scheme for coupling phasor-mode and electromagnetic transients simulations. In each simulation, an iteratively updated linear equivalent is used to represent the effect of the subsystem treated by the other simulation. Time interpolation and phasor extraction methods adapted to this scheme are presented and compared to ...
