Quantifying Heterogeneous Grid-Forming Device Impacts on Power System Dynamics
US & West ·
A decentralized and scalable stability analysis method is proposed for power systems with GFM and GFL converters. Using Davis-Wielandt shells, the impact of heterogeneous GFM integration on system dynamics and stability is analytically derived.
Why it matters
The method enables assessing the impact of new equipment types on large power system stability, crucial for control and planning.
Hanwha Construction, together with E8, Seoul University, and the Korea Institute of Construction Technology, participates in a national project to develop and validate a digital twin-based building energy management simulator using BIM. The project aims to improve energy efficiency.
A four-dimensional framework assesses DeFi decentralization, integrating network theory, agent-based simulation, and longitudinal analysis of 1,956,216 Aave V3 events. The study of GHO issuance on Ethereum and Arbitrum expansion shows varying activity and concentration shifts, highlighting the complexity of decentralization.
A workflow for CPS design-space exploration using reinforcement learning is presented. The RL agent selects subsystem alternatives, and the model is evaluated via simulation with online temporal-property monitors.
