Efficient Transient Simulation of Single-Phase Grid-Feeding Converter System Using Frequency Response Optimized Integrators Considering Second Order Derivative

A novel power system transient simulation scheme based on frequency response optimized integrators considering second order derivative is applied to a single-phase grid-feeding converter system in this paper. The converter system under study is introduced in detail as well as how the different numerical integrators are utilized for each constituting component. Numerical case studies show that the novel transient simulation scheme is able to achieve computational efficiency without sacrificing accuracy.
