摘要
A method includes the steps of providing a common DC bus to interconnect power elements to a DC distribution system using power converters. A first group of one or more of the elements (main element) is used to execute the primary function by automatically maintaining the DC bus voltage following a set point. The DC bus voltage set point is intentionally changed with slow dynamics according to a secondary function executed by the main element such that the average DC bus voltage regulated by the main element changes. A local logic is used on each of the power elements connected to the DC bus but different from the main element to modify their power generation or consumption as a result of changes in the measured average DC bus voltage such that they contribute to the fulfillment of the secondary level of control.
