Dynamic Validation of CNN-Based Surrogate Models for Inverter-Based Resources in Open-Source Solvers

IEEE Open Access Journal of Power and Energy
Traditionally, distribution system planning has focused on steady-state analyses, with limited consideration of dynamic behavior. However, as large or medium-scale inverter-based resources (IBRs), particularly grid-following (GFL) inverters in commercial

Adaptive‐saturation‐based transient stability enhancement for grid‐following inverters

IET Power Electronics
Abstract This paper proposes an adaptive saturation module to enhance the transient stability of grid‐following inverters after voltage‐dip inception and fault‐clearance moment. The equal‐area criterion reveals that a large acceleration area will be obtained due to the step change of current reference according to grid codes, which ...

Modeling and Control of Grid Forming Converters: A Systematic Review

IEEE Access
In electrical power systems where the proportion of synchronous generators (SG) is gradually decreasing, grid-forming (GFM) converters need to be installed and controlled to meet all the system requirements that SGs have provided to date.

Simulation and application analysis of a hybrid energy storage station in a new power system

Global Energy Interconnection
As the proportion of renewable energy infiltrating the power grid increases, suppressing its randomness and volatility, reducing its impact on the safe operation of the power grid, and improving the level of new energy consumption are increasingly ...

Angular Stability Analysis of Parallel Connected Grid-following PV Inverters

2023 IEEE Texas Power and Energy Conference (TPEC), 2023
High penetration of distributed generators (DG) in modern power grids creates angle, voltage, and frequency instabilities. Most of the work in the literature has focused on small-signal stability analysis of single grid-connected inverters without thoroughly investigating their transient stability for large disturbances and interactions between ...

Dynamic Interaction and Stability Analysis of Grid-following Converter Integrated Into Weak Grid

CSEE Journal of Power and Energy Systems
The grid-connected converter with grid-following control (GCC-GFL) for renewable energy sources has a risk of instability when integrated into the weak grid. This paper aims to investigate the dynamic interactions and stability characteristics of the GCC-

An energy storage planning method for improving the security of receiving-end system considering the selection of power conversion systems

International Journal of Electrical Power & Energy Systems
China's power demand in high load density areas is satisfied by a centralized feed of several large-capacity HVDC links, forming a typical receiving-end system, which is facing problems such as shortage of dynamic reactive power and increased risk of ...
