Haitao Zhang et al.

Summary: This paper mainly focuses on the stability-related issues of a grid-tied interlinking converter system. It analyzes the hybrid AC/DC admittance characteristics and uses the General Nyquist Criterion (GNC) to study the stability assessment, instability root cause identification, and instability mitigation of the system. The study results show that the AC and DC sides of the interlinking converter are decoupled under unity power factor, allowing for independent regulation.

Distributed energy resources on distribution networks: A systematic review of modelling, simulation, metrics, and impacts

Juan Caballero-Pena et al.

Summary: Distributed energy resources (DERs) have attracted much attention due to their rapid deployment and expansion in the power sector. DERs mainly include distributed generation and energy storage systems, and they also involve electric vehicles, demand response strategies, and power electronic devices. DERs pose challenges to the power system due to the heterogeneous energy generation from renewable sources, the probabilistic nature of electric vehicle charging, and the integration of power electronic devices by end-users. Research on DER integration has been conducted in both academic and industrial sectors. DERs are commonly modeled using probabilistic approaches, with the most frequently optimized variables being sizing and location. The key variables to analyze during DER integration into the power grid include voltage profile, frequency response, and charging of lines and transformers. DERs can improve the resilience of energy systems by providing voltage and frequency support, reducing energy losses, enhancing power quality indicators, and enabling energy recovery in extreme scenarios.

Impedance characteristics investigation and oscillation stability analysis for two-stage PV inverter under weak grid condition

Ensheng Zhao et al.

Summary: This paper establishes a complete impedance model of a two-stage PV inverter in order to obtain impedance characteristics and reveal stability issues when connected to a weak grid. The model includes PV arrays, front-end Boost converter, and rear-end inverter with output LCL filter. It is found that the DC output impedance of the front-end circuit behaves as a first-order low-pass filter, mainly influenced by the DC-link capacitor. Additionally, a decrease in the integral gain of the outer voltage loop can cause negative resistance and capacitive impedance in the D-axis impedance component, affecting system stability. The stability issues of the PV inverter connected to a weak grid are evaluated using the impedance analysis method with different divisions of source-load subsystems. It is demonstrated that increasing the PLL bandwidth and decreasing the integral gain of the outer voltage loop both lead to oscillation, and increasing the output capacity deteriorates stability margin.

Summary: This paper presents a comparative analysis of a static synchronous compensator (STATCOM) based on battery energy storage system for stability enhancement of offshore wind power plants. The results show that the grid-forming control offers evident stability margin and damping to the WPPs, especially in weak grids, superior to the grid-following STATCOM. The small-signal models and comparative analysis are validated through electromagnetic transients simulations.

DQ-Frame Impedance Measurement of Three-Phase Converters Using Time-Domain MIMO Parametric Identification

Hong Gong et al.

Summary: The article discusses the use of dq-frame impedance model for grid-converter interactions in three-phase systems and proposes a parametric impedance identification method to mitigate the effect of nonzero grid impedance on impedance measurement accuracy. The method allows for obtaining the parametric impedance model directly from time-domain data without using the fast Fourier transform, and only requires a single measurement cycle with simultaneous wideband excitations. The effectiveness of the method is confirmed through simulations and experimental tests.

Control design and small-Signal stability analysis of inverter-Based microgrids with inherent current limitation under extreme load conditions

A. G. Paspatis et al.

Summary: This paper proposes a novel droop controller that ensures a desired inverter current limitation and stable operation of inverter-based microgrids under extreme load conditions. By aligning the inverter current on the d axis, it achieves two main goals: limiting the RMS value of each inverter current during transients and providing rigorous proof of closed-loop system stability for the entire microgrid. The proposed approach simplifies the stability analysis of the microgrid and demonstrates superiority over conventional droop controllers through simulation and experimental validation.

Wideband Harmonic Voltage Feedforward Control Strategy of STATCOM for Mitigating Subsynchronous Resonance in Wind Farm Connected to Weak Grid and LCC HVDC

Gaoxiang Li et al.

Summary: This study analyzes the impedance interactions among wind farm, weak grid, and LCC HVDC, and proposes a wideband harmonic voltage feedforward control strategy using STATCOM to suppress SSR. A constant voltage amplitude-based harmonic extraction method is designed for the proposed damping controller of SSR, which can automatically counteract a constant error induced by the difference between voltage amplitudes V-n and V-r. The validity of the proposed strategy is verified through experimental results.

Case studies and mathematical proofs validate the relationships between the three modeling methods, and experiments confirm the accuracy of the unified frequency-domain model. Engineering insights and recommendations are provided for practical applications.
