[Abstract]:The optimal configuration of DC circuit breakers is of great significance to improve the reliability of DC distribution network and reduce the power loss of users. Based on the minimum cut set method, a method of dividing DC load points is proposed. A model for calculating the cost of power outage loss considering the functional failure of power electronic equipment is established. With the minimum sum of investment operating cost and outage loss cost of switchgear as the optimization objective, the number of circuit breakers is arranged as the number of stages. With the position combination of circuit breakers as the state, the cost of DC circuit breakers decreases greatly with the development of technology. A dynamic programming algorithm for the configuration of DC circuit breakers considering the change of price is proposed. Taking the hand-held DC distribution network as an example, the results show that the method can divide the prices of DC circuit breakers. The optimal allocation scheme corresponding to each interval is obtained.
