Shipboard power systems (SPS) are complex connecting multiple sources, energy storage (ESSs) and various types of loads. However, the fluctuated propulsion loads may lead to a low quality system. In this paper, management system (PMS) is designed for SPS in framework an optimization-based method. With equivalent consumption minimization strategy (ECMS), proposed method able provide optimal powe...

In the field of new energy vehicles, 4WD PHEVs show strong energy-saving potential. A single management strategy, nevertheless, has difficulty achieving potential due to complex, nonlinear system PHEV. To cope with it, a hierarchical strategy (H-EMS) for is proposed in this paper achieve optimization. Firstly, future speed information predicted by prediction method, and upper adopts model predi...

Plug-in hybrid electric vehicles (PHEVs) are developed to reduce fuel consumption and the emission of carbon dioxide. Common powertrain configurations PHEVs (i.e., configuration combustion engine, motor, transmission) can be operated either in series, parallel, or power split mode, whereas with multimode transmissions enable switching between those modes during vehicle operation. Hence, dependi...

To address the problem that a single energy management strategy cannot adapt to complex driving conditions, in this paper, real-time for different conditions is proposed improve fuel economy. First, order accuracy and stability of condition identifier, feature fusion extreme learning machine (FFELM) used identification. Secondly, equivalent consumption minimization (ECMS) offline optimization c...

Train energy saving problem investigates how to control train's velocity such that the quantity of energy consumption is minimized and some system constraints are satis ed. On the assumption that the train's weights on different links are estimated by fuzzy variables when making the train scheduling strategy, we study the fuzzy train energy saving problem. First, we propose a fuzzy energy ...

We investigate a design strategy for subthreshold circuits focusing on energy-consumption minimization and yield maximization under process variations. The design strategy is based on the following findings related to the operation of low-power CMOS circuits: (1) The minimum operation voltage (VDDmin ) of a circuit is dominated by flip-flops (FFs), and VDDmin of an FF can be improved by upsizin...

The hybrid electric vehicle is equipped with an internal combustion engine and motor as the driving source, which can solve problems of short range slow charging vehicle. Making effective energy management control strategy reasonably distribute output power motor, improve efficiency, reduce battery damage. To consumption excessive discharge at same time, a multi-objective based on particle swar...
