Journal ArticleDOI
Impedance specifications for stable DC distributed power systems
TL;DR: In this article, a new forbidden region for impedance ratio Z/sub o/Z/sub i/ on the S-plane is proposed as the system stability margin requirement, based on which the impedance specifications of individual loads are established.
Journal ArticleDOI
A Generalized Droop Control for Grid-Supporting Inverter Based on Comparison Between Traditional Droop Control and Virtual Synchronous Generator Control
Xin Meng,Jinjun Liu,Zeng Liu +2 more
TL;DR: The GDC's controller parameter design is more intuitive and flexible, and this paper provides a distinct design process, and the effectiveness of the proposed control method is validated by the simulation and experimental results.
Journal ArticleDOI
A series active power filter adopting hybrid control approach
TL;DR: In this article, a hybrid control approach for the series active power filter (APF) is proposed, where the reference signal of the compensation voltage needed by the series APF is obtained by detecting both source current and load voltage.
Journal ArticleDOI
A Unified Control Strategy for Three-Phase Inverter in Distributed Generation
Zeng Liu,Jinjun Liu,Yalin Zhao +2 more
TL;DR: In this paper, a unified control strategy that enables both islanded and grid-tied operations of three-phase inverter in distributed generation, with no need for switching between two corresponding controllers or critical islanding detection, is presented.
Journal ArticleDOI
Strategies and Operating Point Optimization of STATCOM Control for Voltage Unbalance Mitigation in Three-Phase Three-Wire Systems
TL;DR: In this paper, the authors proposed control strategies to ensure normal operation of STATCOM in three-phase three-wire systems when severe system voltage unbalance occurs and, furthermore, to mitigate voltage imbalance at the point of common coupling (PCC) whether it is caused by the utility or load.
