Real-time management and control device for energy of micro-grid

Abstract

The invention relates to a real-time management and control device for energy of a micro-grid. A micro-grid organization level agent device is connected with each micro-grid coordinate level agent device and is used for deciding a final control target and action needed to be executed, the micro-grid coordinate level agent device is also connected with at least one micro-grid execution level agent device, the response of the micro-grid coordinate level agent device comes from a demand of the micro-grid organization level agent device and feedback information during the execution process of each sub-task, and the micro-grid execution level agent device is used for executing to control and adjust the task of a control object according to a mathematical model and the state of the control target. The power balance technology and seamless switching under a grid-connection mode, an off-network mode and a grid-connection and off-network switching mode of the micro-grid can be achieved on the basis of a multi-constraint target micro-grid energy real-time dispatching technology such as power grid, power generation, load, energy storage and electrovalence.

Description

technical field [0001] The invention relates to the field of micro-grids, in particular to a real-time energy management and control device for micro-grids. Background technique [0002] Distributed energy resources (DER) are generally defined to include distributed generation (DG), energy storage devices (ES), and systems connected to the public grid. Among them, DG refers to a small power generation system connected to the user side to meet the special needs of end users, mainly including internal combustion engines, micro gas turbines, fuel cells, solar energy, wind power and other power generation systems. Distributed energy has many advantages, such as realizing comprehensive cascade utilization of energy, making up for the lack of stability of large power grids, and being environmentally friendly. negative impact. [0003] Micro-Grid (MG), also known as micro-grid, coordinates and controls distributed power generation, energy storage devices, and loads through the co...

Problems solved by technology

[0006] The traditional micro-grid control adopts single-chip microcomputer or DSP to develop its data processing capability is limited, communication compatibility and real-time performance are relatively poor, and complex micro-grid control algorithms cannot be integrated, it can only meet some simple micro-grid control requirements, and it is very difficult It is difficult to achieve fast real-time energy scheduling, which makes the energy management of the microgrid relatively extensive, and cannot realize on-off grid switching, let alone meet the control requirements of complex micro-grids at the same time, and cannot improve the energy utilization efficiency of micro-grids
