Energy management and control system and method based on two-dimensional bidirectional energy deploying tree

Abstract

The invention discloses an energy management and control system and method based on a two-dimensional bidirectional energy deploying tree. The system includes an internetwork management and control layer, a region control layer and a local control layer; the internetwork management and control layer includes a micro grid energy management system and is used for deploying energy currents in micro grids and coordinating a plurality of micro power grids to realize combined control; the region control layer includes a micro grid central controller and a plurality of micro grids, wherein the micro grid central controller is used for deploying energy of the region control layer and collecting the electric quantity of the local control layer and comprehensively regulating and controlling micro grid operation; and the local control layer includes a distributed power controller and a load controller, and realizes micro grid transient power balance and load management. The method of the energy management and control system is characterized in that an energy deploying search mode is a mode combining random search starting from an upper-level micro power grid with sequential search of micro power grids of the same level, the hit rate of temporary transfer of energy is effectively improved, and system overhead is reduced.

Description

technical field [0001] The invention relates to an energy management and control system and method based on a two-dimensional bidirectional energy allocation tree, which belongs to the technical field of electric power automation, and is particularly suitable for the field of energy management and control in microgrid areas. Background technique [0002] Microgrids generally have multiple micro power sources, such as wind power, photovoltaics, diesel generators, etc. Microgrids can also use the power energy provided by traditional large power grids. The energy management and control system of the microgrid should include at least the following modules: data acquisition and monitoring, microgrid dispatch strategy and economic operation, microgrid state estimation, microgrid security analysis, etc. Among them, the microgrid scheduling strategy and the economic operation module determine how the microgrid efficiently uses distributed energy, how to smoothly switch between vario...
