Power quality with green energy, DDC, and inductively powered EV´s

This paper is concerned with the infrastructure required for electric vehicles (EV) as society moves towards a future where transportation is less dependent on oil, while producing less carbon dioxide, and less pollution. In this future EV´s will become a substantial load on the grid and it is important that this load improves the power quality rather than makes it worse. Here EV´s are inductively charged allowing opportunity charging at multiple points when stationary, and continuous power when moving along the highway. Using Dynamic Demand Control (DDC) the charging load is shown to be beneficial to the grid and suggestions are made on how wind power (or other) Distributed Generation (DG) can assist using DDC to bolster rural power supplies for this purpose. A new protocol combining DG and DDC (DGDC) allows high penetration of wind and simulations are presented to show its effectiveness producing wind power at grid voltage and frequency for small communities, and regulating load in areas of interest in cities. This power can displace conventional power in all applications, including EV charging, while improving the load factor and quality of the grid.
