Abstract

The invention discloses an operation risk control system of a distribution network. Current operation data of distribution network equipment and historical operation data during the healthy operation process are obtained to construct a fault probability model, so that the operation risk of the distribution network can be determined rapidly. When any operation risk occurs in the distribution network, the system can compare the operation state with a sample in a sample base rapidly; and if a sample being identical with or similar to a target state exists in the sample base, a control strategy of the target state is generated rapidly based on the control strategy of the sample. Compared with the prior art, the control system has advantages of low complexity, high evaluation efficiency, accurate control strategy, and fast execution and the like.

Description

[0001] Technical field [0002] The invention relates to the field of power transmission and distribution, in particular to a distribution network operation risk control system. Background technique [0003] The smart distribution network is an important part of the power grid. With the increasing requirements of users for power quality in recent years, the improvement of the overall performance of the distribution network has become an important part of the sustainable and healthy development of the power industry. The fault of the distribution network is an important factor affecting the power quality and power supply reliability. Only by ensuring the safe and stable operation of the distribution network can the safe and reliable operation of the entire power grid be guaranteed. Therefore, it is very necessary to carry out more work in the field of distribution network security and defense, and to study the risk assessment method of the distribution network. Through the risk...
