Linear Active Disturbance Rejection Control Strategy Based on Improved Quasi-Proportional Resonance for the Inner Current Loop of a Grid-Connected Inverter

Nonlinear and asymmetrical loads in microgrids cause severe current distortion and phase unbalance, presenting critical challenges for grid-connected energy storage inverters. Conventional dq-frame Linear Active Disturbance Rejection Control (LADRC) suffers from two key limitatio...

A Droop-Based PI-QPR Control Strategy for Islanded Parallel-Inverter Microgrids

Parallel-inverter microgrids are prone to PCC voltage distortion during islanded operation with nonlinear and unbalanced loads. Virtual-impedance methods can reshape inverter output impedance, but they also add control complexity and may introduce extra voltage drops. This paper...

Low‐Carbon Optimal Dispatch Strategy Incorporating Attention‐Based Dynamic Carbon Emission Factors of Thermal Power Units

Traditional scheduling methods fail to accurately capture the dynamic carbon emission characteristics of thermal power units across different operating stages, leading to inefficient unit selection, increased emissions, and higher operating costs. To address these challenges unde...
