Practical Assessment Method of PV Hosting Capacity in Complex Distribution Network

In the context of dual-carbon, photovoltaic, as a green and clean energy, will present a high-speed development trend. More and more grid-connected photovoltaic will have a non-negligible impact on the operation of the grid. How to assess the PV hosting capacity of the distribution network for photovoltaic energy is an important issue in the development of PV. Therefore, a distributed photovoltaic source hosting capacity evaluation method for complex distribution network is proposed. First, the complex network structure is simplified and the load is simplified. Then, the cyclic dichotomy approximation method is used to solve the photovoltaic hosting capacity according to the simplified structure. Finally, a simulation is conducted to verified the effectiveness of the proposed method. This method has the advantages of simple calculation and small data demand compared with traditional complex calculation.
