AI Technical Summary

Technical Problem

The widespread integration of distributed power sources makes it difficult for power flow control strategies in distribution networks to adapt to bidirectional power flow, increasing the risk of power flow exceeding limits and affecting power supply safety and reliability.

Method used

By acquiring the load information of target equipment in the distribution network system, identifying over-limit equipment and calculating the power flow over-limit quantity, integrating the control schemes for medium-voltage and low-voltage distributed power supply equipment and the operation mode adjustment scheme, a power flow over-limit control scheme for over-limit equipment is formed to carry out power flow control of the distribution network.

Benefits of technology

It effectively solves the problem of power flow exceeding the limit in the distribution network after the integration of distributed power sources, improves the safety and reliability of power supply, and makes full use of the advantages of distributed power sources in terms of observability, adjustability and controllability to flexibly and conveniently realize power flow control.
