SummaryThis paper presents the performance of a single‐phase utility‐tied distribution static compensator (DSTATCOM) with nonlinear load operating under weak grid conditions. The DSTATCOM is controlled by a complex kernel risk‐sensitive p‐power (CKRSP) algorithm. Ever‐increasing nonlinearity of the load, rapidly increasing renewable energy system installed capacity, and rising heating loads, especially during the winter season, lead to various power quality issues that worsen during weak grid conditions. An advanced adaptive control scheme, that is, CKRSP, enforces the system to perform various multifaceted operations, including harmonics suppression, handling rapid load variations, voltage sag and swell, and active and reactive power control at the point of common coupling (PCC) during weak grid conditions. The proposed CKRSP algorithm outperforms conventional control algorithms regarding steady‐state error, convergence speed, and accuracy. During weak grid conditions, the proposed system ensures stable DC bus voltage with a reduced second harmonic component. This further assists the CKRSP control in better extracting the fundamental load current component using a smoother loss component of current . The proposed system can handle various power quality issues during weak grid conditions while ensuring the overall system's stability. The laboratory prototype results show that the presented system performs satisfactorily under weak grid conditions per IEEE 519‐2014 standards.

SummaryA nonlinear control strategy for a solar photovoltaic (SPV) integrated three‐phase multifunctional converter (3PMFC) is proposed in this study. The proposed control approach integrates a Lyapunov function controller (LFC) for the voltage control loop and a model predictive controller (MPC) for the current tracking control loop. The required 3PMFC reference currents are calculated using a variable conductance factor (VCF) technique. The key highlights of the proposed control strategy are as follows: (1) LFC with only one control gain provides less steady‐state error than the proportional integrator (PI) with two control gains, (2) MPC generates the optimal switching signals for the associated converters in the system without using modulation stages, and (3) The VCF approach simplifies the mathematical formulation to derive the required reference current. The effectiveness of the proposed control technique was evaluated using different solar irradiation, DC loads, and AC loads (linear balanced, linear unbalanced, and nonlinear loads). The performance of the proposed control technique has been evaluated and validated in a dynamic operation scenario utilizing MATLAB/Simulink and a real‐time simulator (OPAL‐RT OP4510). The simulation results demonstrate that the proposed control approach outperforms the conventional control strategy in terms of grid current total harmonic distortion (THD) improvement, which is in accordance with the IEEE‐519 standard. The performance evaluated through simulation studies indicates that the 3PMFC can perfectly perform all of its grid‐supported multifunctional services, such as current harmonic compensation, reactive power support, and source current balance, along with injecting active power generated by the SPV into the utility system.
