Electric vehicles (EV) can be used as distributed energy storage devices to provide to the smart grid different regulation services. However, to have enough impact in the grid, the trend is to jointly manage a set of EV by means of a new stakeholder called aggregator. Knowing the availability, mobility habits, and the state of charge (SOC) of each EV battery, the aggregator performs the allocation...
In recent years, the three-phase pulse width modulation controlled voltage source converter (PWM-VSC) has found its way to wide range of applications, among which renewable energy sources and adjustable speed drives are the most common. In order to achieve low harmonic distortion of current at the point of common coupling (PCC), LCL filters are used for grid connection since they ensure higher damping...
A hardware-in-the-loop model of a centrifugal pump is proposed. The new simulator consists of the pump and pipeline imitators built on the basis of the variable speed drives connected via the programmable logical controller and Profibus communication components. The mathematical description of the flow maintenance represents a core of the simulation methodology. To study the system, a series of tests...
