In recent publications statistical model checking (SMC) has been proposed as a method for verifying the performance of finite-set model predictive control (FS-MPC) algorithms applied to power electronics converters. SMC is a powerful method originating from statistics, which can provide statistical evidence of a system's performance in a stochastic environment. In this paper, SMC is applied to a direct matrix converter, which operates in a grid with different harmonic distortion levels and voltage sags. Using the proposed method it is possible to evaluate not only the performance of the control algorithm in terms of the output current distortion but also evaluate the effects of the weighting factor selection and grid distortions on the device utilization. The obtained results show that high grid distortions and voltage sags increase the number of switching cycles. This information can be of great importance to identify the most stressed devices and how the control algorithm can be adapted to extend the lifetime of the devices and thereby the system during different grid conditions at the very early stage of the converter system design.
