Description

Technical field [0001] The invention belongs to the technical field of micro grids, in particular to a wind and solar storage micro grid system in an industrial park. Background technique [0002] Since entering the 21st century, China's resource and environmental problems have become increasingly prominent. In order to achieve sustainable economic and social development, energy conservation and emission reduction strategies must be implemented. The development of clean energy is a key link in the energy conservation and emission reduction strategy. With the comprehensive launch of the Smart Grid strategy of the State Grid Corporation of China, the construction of distributed energy, energy storage and micro grids is in full swing. The establishment and commissioning of various distributed energy sources requires urgent research and solutions to various types of distributed energy and energy storage. As well as the joint control and dispatch of microgrids, the economic operation...
