Calculation and analysis of total supply capability of AC/DC hybrid distribution network considering load balance

With the development of DC source and load, the AC/DC hybrid distribution network has become the development direction of the future distribution network. The calculation of its total supply capability can effectively guide its planning and operation. In order to accurately calculate the power supply capacity of the AC/DC hybrid distribution network, the load transfer method under N-1 fault was first analyzed. Second, a total supply capability calculation model considering load balance was proposed. The operating characteristics of different types of loads are considered in the model. Then the proposed model is solved by NSGA-II. Finally, an example is used to verify the effectiveness of the proposed model and algorithm, and the total supply capability and bottlenecks of AC/DC hybrid power distribution networks with different structures are compared and analyzed.
