Problems solved by technology

[0004] After searching the existing technical literature, it was found that (microgrid group coordinated control communication system, Chinese patent number: 201420075915.4) proposed a microgrid group coordinated control communication system, which is based on power line carrier and does not need to be re-established Network, which significantly reduces the system cost and can realize effective communication at the same time, but the data transmission rate of the system is low, and it is easily affected by interference and cross-modulation between channels; (communication system for connecting microgrid to distribution network, Chinese patent number: 201320600252.9) proposed a communication system for connecting microgrids to distribution networks. The communication system uses a group-level coordination controller to coordinate and control microgrids in multi-microgrids, without considering the communication between the equipment layer and the terminal layer

Abstract

The invention discloses a hierarchical-level multi-time scale communication hardware system and method applicable to an area multi-microgrid. The invention researches the communication system and method of the area multi-microgrid and provides the area multi-microgrid communication system and method based on hierarchical-level multi-time scale. The communication system is composed of a scheduling mechanism energy management system, an area type central control unit, an integrated terminal and load, switch, photovoltaic, energy storage and communication devices. The hierarchical-level multi-time scale communication method is based on communication speeds of different communication modes; the control instantaneity is improved; the communication functions of bottom devices are ensured; and the communication performance and the economical efficiency of the system are optimized.

Description

technical field [0001] The invention relates to the field of micro-grid communication, in particular to a hierarchical multi-time scale communication system and method applicable to regional multi-micro-grids. Background technique [0002] The microgrid system combines distributed power sources, loads, energy storage devices, and control systems to form a small power system, which reduces the impact of distributed power grid connection on large power grids through control strategies. The operation control and management mode of the microgrid is different from that of the conventional power grid. It relies more on the collection and transmission of information. At the same time, the response characteristics of the microgrid equipment have higher requirements for the real-time and reliability of the communication. fundamentals of management. [0003] According to the scope of application, the communication system of the microgrid can be divided into two parts: the monitoring ...
