Soft Open Points Engaged Fault Reconfiguration of Active Distribution Networks with Uncertainty of Generation and Load Demand
Aiming at the problem of active distribution network reconfiguration in the environment of source and load uncertainty,this paper proposes asoft open point engaged fault reconfigurationmethod for active distribution networks considering source-load uncertainty.This method uses chance constraints to express the degree of tolerance of random load shedding caused by uncertain loads and distributed photo-voltaics and combines it as a penalty term with the system operating cost to become the minimization goal of the fault reconfiguration strategy.At the same time,the actionsof soft open points and traditional swit-ches,and network power flow and nonlinear losses of the converters are expressed as constraints of the fault reconfiguration strategy.Through a linear approximation method,the original fault reconfiguration strategy is expressed as a mixed integer second-order cone problem,and then a parallel alternating direc-tion multiplier method based on global consistent optimization is used to solve the strategy.The application effect of the proposed method is demonstrated through 17-node and 34-node power distribution systems.
