POWER MANAGEMENT CONCEPT IN DC DISTRIBUTED SYSTEMS

摘要

A system and method to interconnect several conventional or alternative power generators, loads, and/or energy storage elements physically separated from each other in a DC distribution system. The method includes the steps of providing a common DC bus to interconnect all of the elements in the DC distributed system using power converters. A first group of one or more of the elements (main element) is used to automatically maintain the voltage of the DC link following a set a set point to provide for the load matching. The average DC link voltage (set point) maintained by the main element is intentionally changed in order to indicate all of the other elements connected to the DC bus how they need to modify their power generation or consumption.

1. A method to interconnect several conventional or alternative power generators, loads, and/or energy storage elements physically separated from each other in a DC distribution system, which method comprises:
providing a common DC bus to interconnect all the elements in the DC distributed System using power converters; using a first group of one or more of the elements (MAIN ELEMENT) to automatically maintain the voltage of the DC link following a set point to provide for said load matching; intentionally changing the average DC link voltage (set point) maintained by the MAIN ELEMENT in order to indicate all the other elements connected to the DC bus how they need to modify their power generation or consumption.
