A bipolar dc microgrid features three voltage levels and is capable of transmitting power more efficiently than a unipolar system. This paper proposes a droop control to achieve load sharing and voltage balancing in such a microgrid system. Droop control is adopted to ensure that autonomous sharing of load power can be realized without communication. Moreover, the positive and negative pole voltages...
This paper presents the implementation of a hardware-in-the-loop simulation (HIL) workbench for hybrid AC/DC micro grid. The hybrid AC/DC micro grid integrates both distributed sources and loads in AC/DC systems to respective links directly. For DC system, photovoltaic arrays with boost converter (PVBC), battery with bi-directional DC/DC converter and DC loads are covered. Diesel generator (DGs) and...
With the development of new energy technology, more and more plug-in electric vehicles (PEVs) have appeared in our lives. In vehicle to grid (V2G) information exchange, the method that PEVs use to access the grid for information and vehicular data collection is the key factor that affects the reliability and real-time nature of V2G communication. Vehicular power line communication (VPLC) reuses vehicular...
To provide higher speed and more flexibility, this paper presents a new implementation method of predictive current control (PCC) algorithms for an indirect matrix converter (IMC) using a digital signal processor (DSP) and a field programmable gate array (FPGA). In this method, the SPARTAN-3E FPGA is used as a master controller to execute the PCC and commutation algorithms and the TMS320F28335 DSP...
Real-time simulation has become widely accepted in both academic circles and industry. The technology has been applied to many domains ranging from aerospace power systems to utility power grids. The benefits of real-time simulation are generally realized through rapid control prototyping (RCP) or hardware-in-the-loop (HIL) simulation. When HIL simulation is undertaken, the validity of the results...
