Description

Technical field [0001] The invention relates to an integrated intelligent control method and system suitable for a park-type micro-grid. It belongs to the technical field of flexible direct current transmission. Background technique [0002] With the continuous advancement of microgrid technology, the construction scale and practical level of microgrid continue to improve. It has gradually changed from a small low-voltage (0.38kV) family microgrid containing a single distributed power supply and a smaller load to a multi-distributed power supply And the development of large-scale medium-voltage (10kV) park-type microgrids with larger loads has gradually transitioned from early trials and demonstrations to practical and commercial operations. For these large-scale park-type microgrid systems that will be commercialized, they include all the links in the traditional power system such as power generation, transmission, transformation, and power consumption. It is a relatively small...

Problems solved by technology

The park-type microgrid system has not only microgrid monitoring, but also functions such as power distribution automation, metering automation, and protection information monitoring. According to the traditional grid construction idea, multiple subsystems need to be built according to their different business functions. The construction of dispatching monitoring system, power distribution automation system, metering system, etc. will not only consume a lot of manpower and material resources in the construction process, but also bring great inconvenience to the operation and maintenance of the system after it is put into production. The construction and operation parties have caused great pressure, which is not conducive to the promotion and application of micro-grids in my country. Therefore, it is necessary to consider the intensive construction and operation of park-type micro-grids. On the premise of ensuring the safe and stable operation of micro-grids, build adaptive Integrated intelligent control system of park-type microgrid

[0003] The current micro-grid control system generally only considers the micro-grid monitoring function, focuses on the stable operation of the micro-grid, and does not include functions such as distribution automation, metering automation, video monitoring, and comprehensive energy management. It lacks the practicability of system operation and is inconvenient to apply. in commercial operation
