Problems solved by technology

However, the green energy used by distributed power generation technology, such as wind power and photovoltaics, has high environmental requirements, and the power generation has the disadvantages of intermittent and randomness, and the generated current is unstable. If it is directly applied, it will cause damage to the electrical appliances on the load line.
Invention patent CN201110326620.0 discloses a distributed micro-grid system that utilizes wind energy and light energy to complement each other and comprehensively utilize mains power. The dispatching system is used to intelligently control the micro-grid to solve the shortcoming of the unstable current generated by the micro-grid.
However, the distributed micro-grid system has low intelligence and cannot reasonably predict the power required by the load. When the power generation conditions are bad, it is easy to cause the distribution system to be in a power-deficit state. Supply pressure during peak hours reduces the role of distributed generation systems

Description

[0001] Technical field: [0002] The invention relates to a distributed power generation system, in particular to a multi-agent-based distributed power generation system. [0003] Background technique: [0004] With the development of the economy, the demand for electricity is increasing day by day. At present, the world still uses centralized power generation, long-distance power transmission and large power grid interconnection as the primary way of power generation, transmission and distribution, but its operation costs are high and difficult, and it is difficult to adapt to various power demands. [0005] The microgrid formed by distributed power generation technology has the advantages of small investment, flexible power generation, reliable power supply, clean and environmental protection, etc., and has been widely concerned and applied. However, the green energy used by distributed power generation technology, such as wind power and photovoltaics, has high environmental...
