Description

technical field [0001] The invention belongs to the field of distribution network technology, and in particular relates to a multi-micro-grid collaborative control and system, computer equipment, and a computer-readable storage medium. Background technique [0002] Microgrid is a kind of partial power grid, which is suitable for various distributed electric energy and different types of electric energy users, specifically a small distribution network system composed of distributed power supply, electric energy conversion device, energy storage device, etc. The microgrid can make the distributed power supply run flexibly and efficiently, and fully tap the value and benefits of distributed power generation. It is an optimal configuration of local distributed micro power supply or medium and small traditional power generation methods to provide electricity and heat to nearby loads. special grid. Among them, the scale of the microgrid is between the distributed generation and t...
