Abstract

The invention discloses a distributed power supply system and power supply method. The system comprises a distributed power supply, a controller, and a power supply management mechanism. The distributed power supply and the controller are in mutual signal connection by the power supply management mechanism. A power grid in a specific area is divided into a plurality of regions and thus monitoring of regional powers and electric energy qualities is realized, so that the power distribution can be adjusted autonomously and stability and reliability can be improved. With an automatic bus transfer device, switching between a local power grid and a large power grid can be realized, thereby guaranteeing stable power supplying of the local power grid and avoiding a phenomenon of power grid paralysis due to the large power grid can be avoided. The system and method are suitable for popularization and application.

Description

technical field [0001] The invention belongs to the field of distributed energy technology, and in particular relates to a distributed power supply system and a power supply method. Background technique [0002] In recent years, with the continuous expansion of urban scale and increasing investment in urban infrastructure, all walks of life have shown a momentum of vigorous development. While power consumption continues to grow, the stability of power supply needs to be further improved. The worldwide energy crisis has also given birth to the power industry's demand for new energy. With the enhancement of users' awareness of environmental protection, higher requirements are placed on the reliability and economy of power supply. Distributed power generation technology based on the development and utilization of new energy It has become a new research hotspot in the electric power industry. The combination of distributed power generation and large power grid will become the m...
