The automatic reconfiguration of electric shipboard power systems is an important step toward improved fight-through and self-healing capabilities of naval warships. The improvements are envisioned by redesigning the electric power system and its controls. This research focuses on a new scheme for an energy management system in form of distributed control agents. The control agents' task is to ...

An interactive intuitive graphical simulation package for the analysis of electric distribution systems is presented. It incorporates interactive graphical design of the electric network with a relational data base. The interaction is facilitated with the use of GUI (Graphical User Interface). Two analysis algorithms are integrated allowing the study of load flow conditions as well as the optim...

An energy harvester fabricated by inkjet 3D printing based on miniature water flow turbine with mechanical and electrical components necessary for electrical energy generation is shown. Turbine (outside diameter 25.4 mm (1”) and 14 mm length) is able to generate electric power of 4 mW for 14 L/min of water flow and it gives 0.7 V for optimal load resistance (RL = 55 Ω). The harvester itself may...

An estimator identifying the flow rate through a rotary blood pump was developed. This estimation algorithm uses the pump current and speed signals to estimate the blood flow rate through the pump. The algorithm was derived based on the force balance between the electric torque generated by the motor and the load torque, including the mechanical losses. The corresponding estimator parameters we...

In distribution networks, failure to smooth the load curve leads to voltage drop and power quality loss. In this regard, electric vehicle batteries can be used to smooth the load curve. However, to persuade vehicle owners to share their vehicle batteries, we must also consider the owners' profits. A challenging problem is that existing methods do not take into account the vehicle owner demands ...

This contribution describes the control optimization . Power and energy management are methods applied to hybrid electric powertrain systems to be used in modern vehicles. Hereby the electric current flow with...

Stochastic noises have a great adverse effect on the prediction accuracy of electric power load. Modeling online and filtering real-time can effectively improve measurement accuracy. Firstly, pretreating and inspecting statistically the electric power load data is essential to characterize the stochastic noise of electric power load. Then, set order for the time series model by Akaike informati...
