Abstract

Driven by the "dual carbon" target, it has become a trend for an extremely high proportion of new energy to be integrated into the distribution network. The random "bidirectional flow" of power flow in the distribution network has a great impact on its operational safety. It is urgent to identify the network framework risks and load transfer methods of the distribution network. A risk identification and load transfer calculation method for the distribution network framework considering the integration of new energy is proposed. First, a risk identification method for the distribution network with a high proportion of new energy access is proposed, and its risk quantification indicators are given from the aspects of network structure, operating load rate, power flow factor, power flow transfer entropy, and their comprehensive aspects. Second, considering cascading conditions across multiple high-risk lines in the distribution network, a model for calculating cascading load transfer is proposed. Finally, a case study on an actual power grid is conducted to validate the proposed method, and the results demonstrate its effectiveness.
