Wireless-control strategy for parallel operation of distributedgeneration inverters

by Josep M. Guerrero, José Matas, Luis García De Vicuña, Miguel Castilla, Jaume Miret - IEEE Transactions on Industrial Electronics , 2006
"... Abstract—In this paper, a method for the parallel operation of inverters in an ac-distributed system is proposed. This paper explores the control of active and reactive power flow through the analysis of the output impedance of the inverters and its impact on the power sharing. As a result, adaptive ..."

be properly shared due to the addition of a current harmonic loop in the control strategy. Experimental results are presented from a two-6-kVA parallel-connected inverter system, showing the feasibility of the proposed approach. Index Terms—Distributed generation (DG), droop control method, microgrids

Coil sensitivity encoding for fast MRI. In:

by Klaas P Pruessmann , Markus Weiger , Markus B Scheidegger , Peter Boesiger - Proceedings of the ISMRM 6th Annual Meeting, , 1998
"... New theoretical and practical concepts are presented for considerably enhancing the performance of magnetic resonance imaging (MRI) by means of arrays of multiple receiver coils. Sensitivity encoding (SENSE) is based on the fact that receiver sensitivity generally has an encoding effect complementa ..."

, samples of distinct information content can be obtained at one time by using distinct receivers in parallel (2), implying the possibility of reducing scan time in Fourier imaging without having to travel faster in k-space. In 1988 Hutchinson and Raff (3) suggested dispensing entirely with phase encoding

Self-determination and persistence in a real-life setting: Toward a motivational model of high school dropout.

by Robert J Vallerand , Michelle S Fbrtier , Frederic Guay - Journal of Personality and Social Psychology, , 1997
"... The purpose of this study was to propose and test a motivational model of high school dropout. The model posits that teachers, parents, and the school administration's behaviors toward students influence students' perceptions of competence and autonomy. The less autonomy supportive the so ..."

Transactions on Parallel and Distributed Systems

by Systems C. Special-purpose
"... (MMOGs) can include millions of concurrent players spread across the world and interacting with each other within a single session. Faced with high resource demand variability and with misfit resource renting policies, the current industry practice is to over-provision for each game tens of self-own ..."

Distributed Parallel Operation of Modified Deadbeat Controlled UPS Inverters

by Meng Wang, Fangzheng Li, Yadong Liu, Lipei Huang
"... Abstract- A novel control scheme is proposed for the parallel operation of UPS modules. In this scheme, each UPS in parallel is controlled by a modified deadbeat control method. The traditional deadbeat control has a robust problem to parameter imprecision, which restricts its application. A proport ..."

proportional element is added in the proposed method to solve this problem. The modified deadbeat controlled inverter has good static performance and fast dynamic response and is insensitive to parametric deviation. A distributed control method is used here to realize parallel operation. All the UPS modules

Parallel Planning via the Distribution of Operators

by Dimitris Vrakas, Ioannis Refanidis, Ioannis Vlahavas
"... This paper describes ODMP (Operator Distribution Method for Parallel Planning), a parallelization method for efficient heuristic planning. The method innovates in that it parallelizes the application of the available operators to the current state and the evaluation of the successor states using ..."

A wireless controller to enhance dynamic performance of parallel inverters in distributed generation systems

by Josep M. Guerrero, Luis García De Vicuña, José Matas, Miguel Castilla, Jaume Miret - IEEE Trans. Power Electron , 2004
"... Abstract—This paper presents a novel control strategy for par-allel inverters of distributed generation units in an ac distribution system. The proposed control technique, based on the droop con-trol method, uses only locally measurable feedback signals. This method is usually applied to achieve goo ..."

Parallel-Connected Legs in a Grid-Tied Inverter System for Distributed Generation

by G. J. Capellá, J. Pou, J. Zaragoza, S. Ceballos, I. Gabiola, E. Robles
"... Abstract. Grid-connected high-power inverters are often used in distributed generation and power quality systems. Those inverters have to handle high currents in order to achieve high power values without resorting to higher voltages. Connecting inverter legs in parallel is a proper way to achieve s ..."
