Abstract

The invention discloses a box-type integrated multiple micro source interface micro power grid connected system device. The exterior of the device is a box body of a container cabinet body, and the interior of the box body is of a three-room structure, wherein a front room is an operation room, a middle room is an equipment room, and a rear room is a refrigerating room. The box body adopts an alternative-direct current bus structure, wherein two buses are connected through a converter. In addition, each micro source (a micro flue gas turbine, a photovoltaic battery and a wind driven generator) and energy storage elements (a super capacitor and a storage battery) are connected on an input side of each inside corresponding converter through external terminals outside a container so as to put originally scattered converters into a box-type cabinet body, and are centralized and controlled through control chips taking charges of energy. Construction cost of communication equipment is left out, and work reliability of a micro network system is greatly improved. Compared with a traditional micro network, the box-type structure integrated device reserves operation characteristics of the original micro network, reduces micro network system installment, unloading and transportation difficulties, and is practical.

Description

technical field

[0001] The invention belongs to the field of power electronic micro-grids, and relates to a grid-connected system device, in particular to a box-type micro-grid system grid-connected device that highly integrates multiple different types of power electronic converters. Background technique

[0002] As a beneficial supplement to a single large power grid, the microgrid has great potential for wide application. At present, some major developed countries and regions in the world, such as the United States, the European Union, and Japan, have carried out research on microgrids, and other countries such as Canada, China, and South Korea have also begun to get involved.

[0003] The United States first proposed the concept of microgrid. In 1999, the Consortium for Electric Reliability Technology Solutions (CERTS) conducted research on the reliability, economy and environmental impact of microgrid for the first time. By 2002, a relatively complete micro-grid concep...
