要約(英語): The voltage interpolation model of inverters can accurately simulate the harmonics in inverter current even if it is used with the simulation time step five times larger than the conventional modeling method (SW model). This paper reveals the relation between the simulation time steps and the errors of the simulated current waveform. Then, the simulation of a grid-connected inverter for PV generation systems is executed by using the voltage interpolation model, the SW model, and a conventional circuit average model. The results demonstrate that the voltage interpolation model can reduce the computational time by a factor of three comparing to the SW model while it simulates the resonance, that the circuit average model cannot deal with, accurately.
