Problems solved by technology
The output load is only the grid or the direct end user, which is greatly affected by light, temperature, wind direction, and grid voltage, and cannot provide a stable and reliable power supply for end users, especially for some important places or equipment that require uninterrupted power supply
Therefore, the above devices cannot meet the requirements and cannot adapt to the trend of new energy development in the future.

Description
technical field [0001] The invention belongs to the technical field of new energy microgrid power generation, and in particular relates to a multi-source coordinated control system. Background technique [0002] With the continuous development of social economy and the continuous improvement of people's living standards, people's requirements for power quality are getting higher and higher, especially after entering the 21st century, my country's power construction speed has accelerated, and the scale of power is expanding rapidly. With the construction of the UHV power grid and the implementation of the "Three-Hua" interconnection project, the electrical connections of the power grids at all levels have become increasingly close, and the operating characteristics of the power grid have become increasingly complex. The access to the power grid system has made the test of the safe and stable operation of the power grid more prominent; under these new situations, higher requir...
