Abstract

The invention relates to the technical field of power grid planning and provides a multi-unit multi-bus direct-current micro-grid architecture and a partition hierarchical intelligent control system.The architecture comprise a first large power grid unit, a second large power grid unit, a hybrid energy storage unit, a wind storage power supply unit, a light storage power supply unit, a circuit breaker unit, a public double-direct-current bus unit and a local direct-current micro-grid unit. Each unit is connected with a first common DC bus and a second common DC bus through two corresponding breakers. The first common DC bus and the second common DC bus are respectively connected with a bus circuit breaker in series. According to the invention, the orderly operation of distributed power supply and the efficient utilization of renewable energy sources can be realized, and electric energy can be provided through the local DC microgrid under the condition that the main microgrid cannot provide electric energy, so that the power supply reliability of the load in the system is improved.

Description

technical field [0001] The invention belongs to the technical field of power grid planning, and in particular relates to a multi-unit multi-bus DC micro-grid architecture and a partitioned and layered intelligent control system. Background technique [0002] With the development of the economy and the continuous advancement of the modernization process, energy has become an indispensable part. In the past, fossil energy was the most important form of energy. Although the large-scale development and utilization of fossil energy has greatly promoted economic development and social progress, fossil energy is a limited type of resource, and at the same time it will produce a large amount of polluting gases and greenhouse gases during use, which has prompted The energy crisis and environmental problems are becoming more and more prominent, which is greatly detrimental to the sustainable development of human society. [0003] In order to solve these two problems, the development ...
