Embodiment
[0043] In this example, the overall structural model of the microgrid, the analysis of the load power distribution error between DGs under the traditional droop control strategy, the analysis of the equivalent circuit model including local loads, the improved droop power distribution strategy, the voltage recovery control strategy, and different working methods based on MATLAB The present invention will be further described in several aspects such as the calculation example verification under the condition.
[0044] (1) Microgrid structure model
[0045] A typical DC microgrid structure such as figure 1 As shown, it includes a common DC bus, distributed power sources (including energy storage units) and different types of loads, and each unit is connected in parallel to the common DC bus through corresponding converters. At the same time, the DC microgrid can also be connected to the external AC grid through a grid-connected converter.
[0046] When the external AC grid fail...
