Nonlinear characteristics of photovoltaic generators were recently shown to significantly influence the dynamics of interfacing power stages.
The configuration of the HRESs and interfacing power converters for connecting the energy sources to the AC bus is extensively discussed.
As a consequence, terrestrial microgrids are expected to have a distributed power architecture in which areas with different voltages are interfaced through power electronic converters.
Two MGs consist of photovoltaic and battery units interfaced by power electronic converters.
The mobile phone makers had been embroiled in more than 40 patent lawsuits in Germany, Britain and the United States since 2009 over basic technologies relating to a handset's user interface, power management, antenna and camera.
With the development of power electronic technologies, multiple-port interfacing power converters are becoming more attractive in microgrid.
Figure 4 shows block diagram of centralized energy management scheme, where the DG units include both the energy sources and DG-grid interfacing power electronic converters.
Inspired by this, we propose a cross-interface power saving management (CPSM) scheme, which leverages the existing low-power ZigBee interfaces to wake up the high-power Wi-Fi interfaces on demand towards enabling multi-hop communications in IoT.
In the DG interfacing power electronic converters, the requirements related to the energy source characteristics, the energy storage system, the distribution system configuration, voltage levels, power quality, etc. need to be considered.
In order to reduce the interfacing power quality problems and improve the energy utilization of WEC systems, design and realization of a novel SPF-GP and effective control strategies are studied.
