Problems solved by technology

[0004] However, the existing energy management systems mostly focus on the control strategy itself, and do not specify the hardware implementation process of the system. They cannot be directly applied to the field of multi-energy complementary systems, and are mostly suitable for special systems, such as wind-solar storage systems. Optical storage micro-grid system, optical diesel storage micro-grid system, etc., do not have wide applicability

The present invention can formulate the economical operation and power flow stability control strategy of the multi-energy complementary system through the data collection and analysis of the multi-energy complementary system, and realize energy scheduling of distributed power sources, energy storage system management, load energy efficiency analysis and management, and grid connection / islanding The mode is switched automatically, so that the multi-energy complementary system can operate economically, reliably and friendly.

Description

technical field [0001] The invention relates to an energy management device. Background technique [0002] As the energy crisis, environmental pollution, and climate change become increasingly prominent, new energy power generation technologies represented by wind power and solar power have attracted widespread attention because of their cleanliness and sustainability. However, the new energy power system is random, and the single power generation system is very unstable, which makes it difficult to ablate the large power grid, and a large number of wind and light abandonment occurs. If energy storage is added to regulate, the cost will be too high. In practical applications, wind power and solar power have a strong complementarity. Compared with a single energy system, the stability of the multi-energy complementary system has been greatly improved, and the capacity of the energy storage device has also been reduced. For Users can use complementary energy systems to meet t...
