Description

technical field [0001] The invention relates to an experimental method, in particular to an experimental method based on a wind storage isolated grid system. Background technique [0002] In distributed energy generation, wind power generation is the project with the most mature technology, the most development conditions and good development prospects. However, limited by the acceptance capacity of large power grids, problems such as "difficulty in grid connection" and "abandonment of wind" in the process of large-scale integration of wind power into the power grid have become major problems restricting the development of wind power. In view of the above-mentioned problems of wind power grid connection, experts at home and abroad have proposed wind-storage combined power generation technology. With the reduction of the cost of energy storage devices and the maturity of technology, wind storage isolated grid power generation technology, as an effective form of wind storage ...

Problems solved by technology

Some literatures study the operation mode and planning configuration of isolated microgrids such as wind storage, and propose the configuration scheme and typical network topology of isolated microgrids; some literatures apply the control methods of traditional power grids to isolated microgrids, and propose The master-slave control method and peer-to-peer control strategy of the power grid, and then conduct experimental analysis of different operating states; some research institutions have established experimental systems for isolated micro-grids, and verified wind power from multiple perspectives such as physical simulation and computer simulation. The feasibility of the isolated grid storage system is limited by the experimental conditions and equipment, and needs to be further improved to increase the practical level

The core problem of the stable operation of the wind-storage isolated power supply system is: after losing the support of the large power grid, under various external disturbance conditions, the system must rely on its own adjustment ability to restore a stable operating state

The complexity of this experiment lies in the fact that the isolated wind storage grid has to adapt to changes in various operating conditions, such as energy storage status, fan output changes, system load changes, etc., and the operating conditions are different, requiring the power characteristics provided by the energy storage control to be different. different, and its characteristics are also related to the operating state of the wind storage system
