ABSTRACT:High-level penetration of unmanaged electric vehicle (EV) charging load into distribution grid is affecting the economic operation of the network. Actions are taken through distribution network reconfiguration and using EV charging strategies. The reconfiguration model is formulated with second-order conic programming. A novel radiality constraint is proposed using the connectivity condition, which reduces the number of binary variables by half. A typical unmanaged EV charging profile is derived from National Household Travel Survey. Two charging strategies, i.e. arbitrary delay and peak-avoiding charging, are proposed. The decision of charging delay is co-optimized in the reconfiguration model. Case study on IEEE 33-bus system shows the performance of the model and the impacts of EV on the network reconfiguration.
