– In recent years, Modular Multilevel Converters (MMC) have been widely used in medium/high voltage applications, such as high-voltage direct current (HVDC) systems, and pointed out as a promising solution for battery energy storage systems (BESS) and static synchronous compensators (STATCOM), according to recent research. Especially, in BESS application, the current and voltage conditions in the battery bank are fundamental to evaluate thermal dynamic, reliability, and lifetime. However, depending on the voltage and power levels, MMC is based on hundreds of SMs. Thus, the full MMC system implementation can be costly and complex for operational and reliability tests. In this sense, the so-called mission profile emulators (MPE), have been developed to emulate the voltage and current in an SM and batteries. The MPE eliminates the need to implement the full converter and contributes to more agile tests of the MMC dynamics, resulting in the design of more reliable converters. In addition, the MPE can be used to obtain battery current and arm current spectrum similar to those obtained in MMC. This work presents a detailed design and implementation of the MPE for an MMC-based BESS. The MPE is validated in simulations and in a reduced-scale prototype.

– The control of grid-connected converters in stationary reference frame has been investigated in several works of literature. One of the challenges of this method is in the computation of the current computing current references as a function of power references. In some works, this issue has been solved based on instantaneous power theory equations described in the stationary reference frame. However, this approach can lead to steady-state errors in the injected power if there is an error in the current control loop, which is the focus of this investigation. Firstly, analytical expressions are derived to investigate the effect of current loop steady-state error in the active and reactive power injected into the grid. Then, this paper proposes a closed-loop power control for grid-connected inverters controlled in the stationary reference frame. This strategy is experimentally investigated in two power conversion system configurations for battery energy storage systems. The results indicate that the proposed scheme guarantees zero steady-state error in the injected power even when the current loop presents an amplitude and phase steady-state error.
