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...
A novel scheme of the well-known technique for parallel operation of uninterruptible power supply systems, namely frequency and voltage droop control method, is presented. The innovation relies on active power estimation, together with the use of a piecewise-continuous nonlinear function, in order to eliminate the need for costly cascaded low-pass filters usually employed to estimate the reacti...
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...
11 This paper proposes a new statistical technique for deciding which of two theories is better supported 12 by a given set of data while allowing for the possibility of drawing no conclusion at all. Procedurally 13 similar to the classical hypothesis test, the proposed technique features three, as opposed to two, 14 mutually exclusive data classifications: reject the null, reject the alternati...
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Micro-grid is a novel conceptual power system for smooth installation of many Distributed Generators which is used for distributing the power in order to provide high quality. The most of micro-grids adopt ac distribution as well as conventional po...
Motivated by the recent interest in smart grid technology and by the push towards distributed and renewable energy, we study the parallel operation of DC/AC inverters in a lossless microgrid. We show that the parallel interconnection of DC/AC inverters equipped with conventional droop controllers is precisely described by the Kuramoto model of coupled phase oscillators. This novel description, ...
