Power clipping method and system
First Claim
1. A method for use with a plurality of elements, the elements including one or more sources and one or more loads, the method comprising the steps of:
- providing a regulated DC link adapted to carry power required by the one or more loads over a predetermined operating voltage range;
coupling each of the one or more sources to the DC link using power conversion devices in a manner such that each of the one or more sources can operatively deliver the power to the DC link throughout the predetermined operating voltage range of the DC link;
coupling each of the one or more loads to the DC link either directly or through a power converter in a manner such that each of the one or more loads can operatively withdraw the power from the DC link throughout the predetermined operating voltage range of the DC link;
varying an amount of power exchanged between the DC link and one or one group of the elements to regulate a DC link voltage following a set point that is a function of the power exchanged and a constraint other than the power exchanged; and
in respect of each of one or more of the elements other than the one or one group of elements, automatically varying the amount of power exchanged between the DC link and the each of the one or more of the elements other than the one or one group of elements in response to the a filtered value of a measured voltage of the DC link.

Abstract
An improved method for controlling an electrical distribution system of the type having a plurality of electrical sources, a load, a DC link coupling the electrical sources to the load and a control means for controlling the output of at least one of the plurality of electrical sources so that the plurality of sources deliver to the load an amount of power appropriate to the load. The improvement comprises an adaptation in respect of the load that provides for the DC link voltage to vary; and an adaptation of the control means resulting in the output being controlled as a direct function of the DC link voltage.
