Bidirectional sensitive power flow confidence evaluation algorithm for microgrid integration into distribution network

The power of the grid-connected port is directly related to the operation state of the source network load inside the microgrid, and the power of the grid-connected port affects the power flow distribution of the whole distribution network. It is of great significance for the planning of distribution network and microgrid, and its safe and stable operation to reasonably evaluate the power flow of microgrid connected to the distribution net? work port. Therefore, a bidirectional sensitivity power flow confidence evaluation algorithm for microgrid merging into distribution network is proposed. Firstly, combined with the state of source network load in mi? crogrid and the prediction results of new energy generation and load power, the probability power flow confi?dence model of microgrid merging into distribution network was constructed. Secondly, combined with the topo? logical structure of distribution network, the power flow distribution confidence model of microgrid merging into distribution network was constructed. This bidirectional confidence model can specifically evaluate the influ? ence of source network load in microgrid on the power flow distribution of distribution network. Finally, the ex? ample results show the feasibility and effectiveness of the proposed bidirectional sensitivity model in the interac? tive analysis and power flow confidence evaluation of microgrid and distribution network.
