Problems solved by technology

The controller of the traditional load control system is the dispatching system or the dispatcher. Users, as power users, do not participate in the load control. When a region is short of electricity, the dispatching can only take the case of ensuring important loads. Power outages take turns in the region. Can only passively accept scheduling arrangements

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the drawings. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0034] figure 1 It is a schematic diagram of the structural connection of a user-definable smart microgrid load control system of the present invention, including a microgrid central controller, a microgrid communication network, a microgrid bus, a user load controller, a smart line switch, and a microgrid bus Grid-connected inverters are respectively connected to distributed power sources such as diesel generators, energy storage batteries, photovoltaics, and wind power. Distributed power sources form an energy storage system. The PCC point is the public coupling point, which is the connection between the micro grid and the large grid point.

Abstract

The invention discloses a user customizable intelligent micro grid load control system. The system is characterized in that the system includes a micro grid load central controller, a user load controller, a user load management module, an intelligent line switch and an uninterrupted power source, wherein the micro grid load central controller is connected with the user load controller and the user load management module respectively through a micro grid load communication network, and the user load controller is connected with the intelligent line switch through the micro grid load communication network. The invention also provides a user customizable intelligent micro grid load control method. With the user customizable intelligent micro grid load control system and method of the invention adopted, a user can participate in the construction of a micro grid load control system and fine management of load; and a load removing mode can be adopted, and therefore, the energy difference of a micro grid can be flexibly configured, and the demands of more users can be ensured finitely in power shortage.

Description

Technical field [0001] The invention relates to a user-definable intelligent micro-grid load control system and method, and belongs to the technical field of micro-grid load control. Background technique [0002] The load control in the microgrid is a means to ensure the safety and stability of the entire microgrid. At the same time, the intelligence of the microgrid load control system also has a positive effect on the energy efficiency management of the microgrid. The core idea of ​​the energy efficiency management of the microgrid is: under the premise of ensuring important loads, priority should be given to efficiency and fairness, and the system should be open and users can participate. The so-called important load refers to: interruption of power supply will cause significant political and economic losses to power users or equipment; interruption of power supply will affect the normal work of power users of major political and economic significance; interruption The power ...
