Abstract

The invention discloses a micro-grid region energy control system and control method. A micro-grid region comprises one or more micro-grid units; each micro-grid unit comprises a unit energy router and at least one set of new energy power generation equipment, energy storage equipment and electricity utilization equipment; the micro-grid region is provided with a region energy router; the micro-grid region is connected with a public power grid through the region energy router; the micro-grid region is provided with a region new energy power generation device and region energy storage equipment which are shared by the multiple micro-grid units; and the region new energy power generation device and the region energy storage equipment are connected with the region energy router. The micro-grid region energy control system solves the problem that a micro-grid energy control system is relatively low in stability in the prior art, meets a peak-alternation operation requirement of a power grid, reduces the electricity utilization cost and also improves the utilization efficiency of new energy power generation.

Description

technical field [0001] The present invention relates to the technical field of micro-grid energy control, in particular to a micro-grid area energy control system and control method. Background technique [0002] Judging from the development trend of energy use, traditional mineral energy pollutes the environment more and more seriously, and its overall use ratio will be more and more restricted; new energy technologies are developing rapidly and their costs are getting cheaper and cheaper. Therefore, the development and utilization of new energy is on the rise. However, the disadvantage of new energy sources, such as photovoltaic power generation and wind power, is that the output power cannot be supplied stably. This leads to the phenomenon of limiting photovoltaic output, abandoning wind and other new energy waste and insufficient utilization. [0003] Aiming at the problem of poor stability of the microgrid energy control system in related technologies, no effective so...
