Due to the poor application effect of current methods in the coordinated optimization scheduling of AC/DC flexible distribution networks,not only the capacity limit rate of distribution network lines is high,but also the line loss rate is relatively high,which cannot achieve the expected scheduling effect. The risk-measurement based coordination and optimization scheduling method for AC/DC flexible distribution networks is proposed. The comprehensive analysis method is adopted to measure the operational risks of the distribution network,and an optimization objective function is established with the goal of minimizing risks. The power flow and active power of the distribution network are constrained by setting constraints. The particle swarm algorithm is used to solve the objective function,determine and execute the optimal coordinated scheduling strategy,and thus complete the coordinated optimization scheduling of the AC/DC flexible distribution network considering risk measurement. The experimental results show that under the application of design methods,the capacity limit rate and line loss rate of AC/DC flexible distribution networks are both less than 1％,which has good scheduling effect and good application prospects in the coordinated optimization scheduling of AC/DC flexible distribution networks.
