With the advance of insulated gate bipolar transistor (IGBT) converters, Multi-Terminal DC (MTDC) based on the voltage-source converter (VSC) has developed rapidly in renewable and electric power systems. To reduce the copper loss of large capacity and long distance DC transmission line, an improved droop control design based on optimal power sharing in VSC-MTDC integrating offshore wind farm i...
In recent years, an ongoing increase of grid-connected distributed and renewable electricity generation technologies is clearly noticeable. From an environmental perspective, the increase of renewable technologies is highly desirable, as they do not emit greenhouse gasses and thus not contribute to climate change. Nevertheless, their increase poses increasing challenges on the reliable operatio...
For islanded microgrids, droop-based control concepts have been developed both in single and three-phase variants. The three-phase controllers often assume a balanced network; hence, unbalance sharing and/or mitigation remains a challenging issue. Therefore, in this paper, unbalance is considered in a three-phase islanded microgrid in which the distributed generation (DG) units are operated by ...
The grid-forming converter is an important unit in the future power system with more inverter-interfaced generators. However, improving its performance still a key challenge. This paper proposes generalized architecture of from view multivariable feedback control. As result, many existing popular control strategies, i.e., droop control, synchronization virtual synchronous generator matching dis...
This letter proposes a general decentralized control of single phase cascaded inverters-power factor angle droop control. Compared to the existing strategies, it has following attractive benefits: 1) is suitable for both grid-connected and islanded modes; 2) Seamless transition between different modes can be obtained; 3) stability condition in mode independent transmission line impedance; 4) su...
This paper presents a resilient cache memory for dynamic variation tolerance in a 40-nm CMOS. The cache can perform sustained operations under a large-amplitude voltage droop. To realize sustained operation, the resilient cache exploit 7T/14T bit-enhancing SRAM and on-chip voltage/temperature monitoring circuit. 7T/14T bitenhancing SRAM can reconfigure itself dynamically to a reliable bit-enhan...
This paper proposes a novel distributed secondary controller for droop-controlled microgrids to regulate the frequency and voltage, autonomously share power mismatch. The proposed scheme is entitled generalized proportional-intergal finite-time (GPI-FTC). GPI-FTC synthesized based on control Lyapunov function method modifying conventional PI by adding consensus term integrand dynamic. provides ...
