Integrated monitoring-based energy management system for microgrid

Abstract

The invention relates to an integrated monitoring-based energy management system for a microgrid, which comprises a local control layer, a network communication layer and a main station layer, whereinthe main station layer comprises a first main engine, a second main engine, a first working station and a second working station; the local control layer comprises a measurement and control protection device, a fan management subsystem, a battery management subsystem, an energy storage inverter, and a photovoltaic array management subsystem; the network communication layer comprises a wireless communication network; and the local control layer is in communication connection with the main station layer through the wireless communication network. The system is an integrated management system with a friendly user interface and good extensibility, microgrid operation optimization policy research can be carried out, dispersed clean energy sources can be centralized and used efficiently and provided for a user in a safer, more reliable and more environmental-friendly mode, energy is saved, the quality of electric energy is improved, grid losses are reduced, and carbon dioxide emission reduction is realized.

Description

technical field [0001] The invention relates to an energy management system based on comprehensive monitoring of a microgrid. Background technique [0002] Energy is an important material basis and strategic resource for economic and social development. Climate change and energy issues have placed urgent demands on countries around the world for low-carbon development. On the one hand, with the development of the economy, the increase of population and the acceleration of urbanization, the demand for energy is increasing rapidly. The extensive use of fossil energy has caused environmental pollution and greenhouse gas emissions, and environmental problems have become increasingly prominent. On the other hand, since fossil energy itself is a non-renewable energy source, continuous consumption also causes resource depletion. Improve energy utilization rate, develop clean energy, optimize and adjust energy consumption structure, reduce dependence on fossil energy, improve energ...
