A source/network/storage/load coordination management system and method for energy internet service

Abstract

The invention discloses a source / network / storage / load coordination management system and method for energy Internet services, the system includes a source / network / storage / load intelligent management system and a source / network / storage / load interconnection communication system; The communication system uses the communication network to realize the collection and monitoring of system metadata, and provides communication support for the control commands of the intelligent control system. The intelligent control system is designed as a three-layer structure of demand layer, state layer and control layer. By setting the comprehensive coordination control and optimization management of source / network / storage / load, it can achieve the goals of supply and demand balance, maintenance of power quality, and demand side management. Based on the development requirements of the Energy Internet, the present invention provides a highly autonomous and fast-response energy management strategy for energy interconnection, and realizes the efficient utilization of distributed power sources under the Energy Internet architecture.

Description

technical field [0001] The present invention relates to the field of energy internet and distributed power supply, in particular to a source / network / storage / load coordination management system and method applied to energy internet. Background technique [0002] The rapid development of distributed power supply, communication and control technology has brought about the rise of research fields such as smart grid and active distribution network. The comprehensive management of electric energy covers all aspects of electric energy production, transmission, distribution and consumption, which can further improve the consumption level of distributed renewable energy, and take into account the system economy and safety. The emerging energy Internet is a new development direction of the energy system, aiming to create an energy interconnection circle with horizontal multi-energy complementarity and vertical source / network / storage / load coordination and interaction, to maximize the u...

Problems solved by technology

At present, researches at home and abroad focus on the regional internal autonomy within the scope of the microgrid, seldom involve the optimization and coordination with the grid, and focus on the single or partial coordinated control of distributed power sources and energy storage devices. As a research that can coordinate and optimize management as a whole, it fails to provide strong support for economic load distribution

Relevant coordination and management methods may be weak in hierarchy, the amount of data in the main control center is too large, the control requirements at the level of the Energy Internet have not been met, or only framework suggestions are made, the management structure is loose, and the response speed and flexibility in actual application will be affected. restricted
