High Efficiency and Full MPPT Range Partial Power Processing PV Module-Integrated Converter

Mohammad Daryaei et al.

Summary: To increase the energy yield of PV systems, MPPT should be performed by module-level converters. However, using module-level converters adds a constant loss. This article proposes the concept of partial power processing and designs a new high-frequency and high-efficiency module-integrated PV converter that can achieve full range MPPT.

A Novel Resilient Control of Grid-Integrated Solar PV-Hybrid Energy Storage Microgrid for Power Smoothing and Pulse Power Load Accommodation

Manoja Kumar Behera et al.

Summary: To tackle the adverse impact of pulse power loads and fluctuating PV power on grid stability, a hybrid energy storage system (HESS) is proposed, which integrates hydrogen/bromine redox flow battery and supercapacitor. The system incorporates an antiwindup mixed-order generalized integrator, an improved sparrow search algorithm tuned tilt integral-derivative with filter controller, and a fast-acting adaptive dc-link power-based energy management control. The effectiveness of the proposed system and control strategies are confirmed through MATLAB simulation and OPAL-RT real-time simulator test bench.

Discrete Multiple Second-Order Generalized Integrator With Low-Pass Filters and Frequency-Locked Loop for DC Rejection

Haoyang Zheng et al.

Summary: This article proposes a modified discrete method to eliminate the dc offset issue in parallel second-order generalized integrators (SOGI) in digital implementation. A discrete low-pass filter (LPF) is introduced to remove the dc offset in the discrete SOGIs, and a discrete multiple-channel SOGI-LPF is formed by paralleling multiple discrete SOGI-LPFs to extract different frequency components. Additionally, a discrete frequency-locked loop (FLL) is proposed to estimate the frequency of the input signal and achieve good dynamics. The stability analysis based on discrete linear-time periodic (LTP) model is provided.
