“…The insignificant power losses include (1) blocking losses, (2) driving losses, and (3) the diode turn-on losses [4]. The significant losses consist of (1) the conduction losses related to the desired output (minimizing this part is not attractive), (2) on-off losses in IGBTs, and (3) turn-off diode losses [5]. In this work, the last two terms-switching and recovery losses-are considered as one objective function.…”

Abstract:The performance optimization of the two-level, three-phase, grid-feeding, voltage-source inverter (VSI) is studied in this paper, which adopts an online adaptive switching frequency algorithm (OASF). A new degree of freedom has been added to the employed OASF algorithm for optimal selection of the weighting factor and overall system optimization design. Toward that end, a full mathematical formulation, including the impact of the coupling inductor and the controller response time, is presented. At first, the weighting factor is selected to favor the switching losses, and the controller gains are optimized by minimizing the integral time-weighted absolute error (ITAE) of the output active and reactive power. Different loading and ambient temperature conditions are considered to validate the optimized controller and its fast response through online field programmable gate array (FPGA)-in-the-loop. Then, the weighting factor is optimally selected to reduce the cost of the L-filter and the heat-sink. An optimization problem to minimize the cost design at the worst case of loading condition for grid-feeding VSI is formulated. The results from this optimization problem are the filter inductance, the thermal resistance of the heat-sink, and the optimal switching frequency with the optimal weighting factor. The VSI test-bed using the optimized parameters is used to verify the proposed work experimentally. Adopting the OASF algorithm that employs the optimal weighting factor for grid-feeding VSI, the percentages of the reductions in the slope of the steady state junction temperature profile compared to fixed frequencies of 10 kHz, 14.434 kHz, and 20 kHz are about 6%, 30%, and 18%, respectively.

This paper proposes an efficient hybrid approach-based energy management strategy (EMS) for grid-connected microgrid (MG) system. The primary objective of the proposed technique is to reduce the operational electricity cost and enhanced power flow between the source side and load side subject to power flow constraints. The proposed control scheme is a consolidated execution of both the random forest (RF) and quasioppositional-chaotic symbiotic organisms search algorithm (QOCSOS), and it is named as QOCSOS-RF. Here, the QOCSOS can have the capacity to enhance the underlying irregular arrangements and joining to a superior point in the pursuit space. Likewise, the QOCSOS has prevalence in nonlinear frameworks due over the way that can insert and extrapolate the arbitrary information with high exactness. Here, the required load demand of the grid-connected MG system is continuously tracked by the RF technique.The QOCSOS optimized the perfect combination of the MG with the consideration of the predicted load demand. Furthermore, in order to reduce the influence of renewable energy forecasting errors, a two-strategy for energy management of the MG is employed. At that point, proposed model is executed in MATLAB/Simulink working platform, and the execution is assessed with the existing techniques.

Summary This paper develops model predictive control with a finite control set (FCS‐MPC) for a static synchronous compensator (STATCOM) based on hybrid cascaded H‐bridge and neutral point clamped (HC‐HNPC) multilevel inverter. By applying FCS‐MPC to basic multilevel structures such as the cascaded H‐bridge (CHB), the dynamic performance is improved; but, as the number of output voltage levels increases, the method suffers from a high computation burden as a result of a significant number of switching states. In HC‐HNPC based STATCOM, the number of power switches and switching states is reduced compared to CHB STATCOM for an equal number of output voltage levels. As a result, while keeping the number of output voltage levels the same as CHB, the FCS‐MPC computational burden decreases, and the control objectives are achieved easier. Furthermore, HC‐HNPC STATCOM as a hybrid multilevel STATCOM contains different types of cells with different capacitors voltage. Utilizing the introduced FCS‐MPC, each capacitor voltage is kept balanced without using a complex balancing system. For a detailed investigation, a single‐phase 9‐level HC‐HNPC is employed in this research. The FCS‐MPC control is developed for 9‐level HC‐HNPC STATCOM and the mathematical equations are extracted. Finally, the control performance is verified by simulation and validated with experimental results.
