Method for use of static inverters in variable energy generation environments
First Claim
Patent Images
1. A method of generating energy comprising:
- producing direct current (DC) voltage via one or more variable energy collecting units;
maintaining a desired level of the DC voltage on a bus via a first controller in communication with the units;
delivering the desired level via the bus to a static converter;
converting via the static converter the desired level to an alternating current;
outputting the alternating current to a pulse width modulation inverter wherein the pulse width modulation inverter converts the alternating current to a modified alternating current;
controlling a current flow of the alternating current between the static converter and the pulse width modulation inverter via the first or the second controller.

Abstract
A method to collect energy from generation systems such as, for example, wind farms or solar farms with widely distributed energy-generation equipment. In some cases, static inverters are used to feed the energy directly into the power grid. In some other cases, back-to-back static inverters are used create a high-voltage DC transmission line to collect power from multiple generation sites into one feed-in site.
