As the design complexity continues to increase, huge peak power has become an important concern. A widely used power management technique is to shut down unused operations. However, an unused operation cannot be shut down, unless all the operations involved in identifying the control/data flow of this operation have been scheduled before this operation. Therefore, operation scheduling has a sig...

Received Jun 19, 2017 Revised Aug 15, 2017 Accepted Sep 7, 2017 This manuscript presents a feeder reconfiguration in primary distribution networks with an objective of minimizing the real power loss or maximization of power loss reduction. An optimal switching for the network reconfiguration problem is introduced in this article based on step by step switching and simultaneous switching. This p...

Network reconfiguration which is constrained non linear optimization problem has been solved for loss minimization, load balancing, etc. for last two decades using various heuristic search evolutionary algorithms like binary particle swarm optimization, neuro-fuzzy techniques, etc. The contribution of this paper lies in considering distributed generation which are smaller power sources like sol...

Power distribution systems face continuous challenges from increased demand and lengthening of feeders, resulting in power loss augmentation unacceptable voltage drops. Thus, to reduce technical losses improve the profile, common techniques such as reactive compensation, network reconfiguration, placing regulators are employed. Distribution reconfiguration (DNR) consists modifying system topolo...

This paper describes a gate-level power minimization methodology using dual supply voltages. Gates and flip-flops off the critical paths are made to operate at the reduced supply voltage to save power. Core technologies are dual-V DD circuit synthesis and P&R. We give a brief overview on existing low-power EDA technologies as background and discuss advantages and challenges of the dual-VDD appr...

Stochastic Dual Coordinate Ascent is a popular method for solving regularized loss minimization for the case of convex losses. In this paper we show how a variant of SDCA can be applied for non-convex losses. We prove linear convergence rate even if individual loss functions are non-convex as long as the expected loss is convex.

2 I. INTRODUCTION Power system economics procedure includes of two aspects: active power regulation and reactive power dispatch. This forms a global optimization problem of a large-scale industrial system.The reactive power problem is less manageable to solve than the active power problem due to its more complicated relationship between variables. The reactive power problem is largelyassociated...

In this paper, a new topology for cascaded multilevel converter based on sub multilevel converter units and full-bridge converters is proposed. The proposed topology significantly reduces the number of dc voltage sources, switches, IGBTs, and power diodes as the number of output voltage levels increases. Also, an algorithm to determine dc voltage sources magnitudes is proposed. To synthesize ma...
