Background
The micro-grid is a small power generation and distribution cluster organically integrating a distributed generator, a load, an energy storage system, a current transformer and a monitoring and protecting device. The microgrid may be classified into an ac microgrid and a dc microgrid. Compared with an alternating-current micro-grid, the direct-current micro-grid has the characteristics of low cost, high operation efficiency, simplicity in control and the like. With the emergence of a large number of dc loads, the importance and necessity of dc micro-grids has received a great deal of attention. At present, there are two main methods for controlling the voltage stability of the dc bus of the dc microgrid: centralized and distributed. In the centralized control scheme, a micro-grid central controller needs to be arranged, and the micro-grid central controller sends a control instruction to a controlled unit after acquiring all power generation units and load information and performing complex calculation processing, so as to realize the control target of the system. The communication network required by the control mode is extremely large, complex and high in cost, and meanwhile, under the condition that communication fails or is not timely communicated, the system cannot make timely and effective response, and the safety and reliability of the system are affected.
In summary, the problems of the prior art are as follows: the existing direct current type micro-grid can be connected to a power utilization network only by using a direct current and alternating current converter, and the use cost is increased.
