含SOP的交直流混合配电网日前优化调度OACSTPCD

To achieve the economic operation of AC/DC hybrid distribution network,an optimal scheduling method for the hybrid distribution network considering soft open point(SOP)is proposed.On the basis of the elaboration of the working principle of SOP which is applied to the hybrid distribution network,an optimal scheduling model considering SOP is established.Through the linearization and convex relaxation techniques,the established nonlinear optimization model is transformed into a second-order cone programming model,and the effectiveness of the established model is ver-ified with an improved 50-node test system as an example.Results show that the SOP operation strategy obtained based on the established model can reduce the operation loss of distribution network,alleviate the voltage overrun,and signifi-cantly improve the economy of the hybrid distribution network.
