Abstract

The invention discloses a model-self-adapting-based energy optimal control system of a microgrid. The system comprises five logic levels: an equipment layer, a model layer, a calculation layer, a service layer, and an application layer, wherein the layers are connected in sequence. In addition, the invention also discloses a design method of a model-self-adapting-based energy optimal control system of a microgrid. The design method includes: power grid information, information of all distributed power supplies, and load information and the like are collected based on a real-time monitoring system; and equipment classification, model establishment, calculation optimization, energy configuration responding, and real-time application monitoring are carried out on the collected information. Therefore, the overall development cost and period of the energy management system are reduced; the optimal power matching among the power grid, all distributed power supplies, energy storage and loads can be realized; and flexible control of all distributed power supplies in island and grid-connected operation modes as well as optimized operation of the system also can be realized.

Description

technical field [0001] The invention relates to a model-adaptive-based micro-grid energy optimization control system, and also relates to a design method for a model-based self-adaptive micro-grid energy optimization control system, which belongs to the technical field of micro-grids. Background technique [0002] The new energy microgrid is based on the construction of local distribution networks. Various distributed energy sources such as wind, light, and natural gas are multi-energy complementary, and have a high proportion of new energy power access. Local energy production and consumption can be realized through energy storage and optimized configuration. It is a local area network for comprehensive utilization of smart energy that can interact flexibly with the public power grid as needed and operate relatively independently. The new energy microgrid can be a single new energy microgrid, or a microgrid group composed of multiple new energy microgrids in a certain area....
