Evaluating load flow capability with thermostically controllable building loads
2015 North American Power Symposium (NAPS), 2015Through demand side management programs, buildings are increasingly being used to provide respite where generation inadequacies exist. Buildings are commonly dispatched as thermostatically controllable loads by adjusting internal temperature setpoints. Thermal load variations can be attributed to the HVAC equipment and are highly dependent on internal ...

Flow Control of Extreme Pressure Loads Associated with Flow Separation
Journal of Engineering Mechanics, 2016AbstractActive flow control is applied at different locations over a surface-mounted prism to reduce extreme pressure coefficient and loads. Different control strategies including blowing, suction, and synthetic jets are evaluated. The full unsteady Navier–Stokes equations are solved to determine the pressure coefficients.

A Load Control Mechanism for Data‐Flow Machines
Systems and Computers in Japan, 1988AbstractThe data‐flow computer is based essentially on parallel computation. Consequently, it is essential in the realization of such high‐level management and control functions as resource management to control the parallelism and parallel expansion.

Flow Stealer: lightweight load balancing by stealing flows in distributed SDN controllers
Science China Information Sciences, 2017Software-defined networking (SDN) introduces centralized controllers to increase network programmability drastically. Distributed control planes, in which multiple SDN controllers work together to manage a network, have been proposed to satisfy the requirements of large-scale networks, and different kinds of load-balancing approaches have been proposed

Control setting of unified power flow controllers through a robust load flow calculation
IEE Proceedings - Generation, Transmission and Distribution, 1999The unified power flow controller (UPFC) provides a promising means to control power flow in modern power systems. Essentially, the performance depends on proper control setting achievable through a power flow analysis program. The paper presents a reliable method to meet the requirements by developing a Newton–Raphson based load flow calculation ...

Study on load frequency control using Redox flow batteries
IEEE Power Engineering Society General Meeting, 2004., 2004Summary form only given. Rechargeable batteries such as Redox flow, which are not aged by frequent charging and discharging, have a quick response equivalent to SMES and outstanding function during overload. The battery efficiency increases when the cycle period of charging/discharging becomes shorter.

Load Sensing Hydraulic Flow Control - A Versatile Controller
SAE Technical Paper Series, 1978<div class="htmlview paragraph">A simple spool valve combined with load sensing principles is used for precision flow control on demand. This type of valve, even though it has been in use for about ten years, received new attention during the energy crunch of 1974 and the subsequent interest in load sensing systems The load sensing flow control ...

The performance of adaptive window flow controls in a dynamic load environment
Proceedings. IEEE INFOCOM '90: Ninth Annual Joint Conference of the IEEE Computer and Communications Societies@m_The Multiple Facets of Integration, 2002The behavior of window flow control schemes that adapt to changing network conditions is studied. A dynamic window scheme, which adjusts the window size based on explicit network congestion indicators, is proposed. The throughput performance of the adaptive policy under both steady-state and nonstationary conditions is studied.

OmniFlow: Coupling Load Balancing with Flow Control in Datacenter Networks
2016 IEEE 36th International Conference on Distributed Computing Systems (ICDCS), 2016In this paper, we propose OmniFlow, a novel transport protocol which combines load balancing and flow control at the transport layer to optimize datacenter transfers. OmniFlow outweighs previous solutions in two aspects. Firstly, it can simultaneously and precisely measure the queueing latencies on multiple paths between two hosts.

Dynamical model of unified power flow controllers in load-flow analysis
2006 IEEE Power Engineering Society General Meeting, 2006Based on the novel concept of interpreting the updated voltage solutions at each iteration in the Newton-Raphson (NR) load-flow analysis as dynamic variables, the paper develops a procedure for representing the unified power flow controllers (UPFCs) in the steady-state evaluation.
