Description

technical field [0001] The present invention relates to a micro-grid control technology, in particular to a wind-solar distributed power generation independent micro-grid energy management coordination control system and method. Background technique [0002] At present, the main way to solve the problem of electricity consumption in areas without electricity is to apply single-energy household power generation systems such as small wind power or photovoltaic power generation, and there are also a few households that use wind and solar hybrid systems. Fundamentally speaking, these small-scale renewable energy power generation methods have shortcomings such as small capacity, low product efficiency, poor power supply reliability, and high power generation costs, which greatly hinder the large-scale application and further development of such power generation systems. [0003] If the geographically adjacent wind and wind distributed power sources form a self-contained independe...

Problems solved by technology

Due to the spatial dispersion of distributed power sources, energy storage, and loads in an independent microgrid, if it relies on wired networks to transmit control signals, the construction is complex and the cost of laying lines is high, the cost of maintenance is high, and the flexibility of installation equipment is poor
