To address the problems of voltage violations and voltage fluctuation caused by high penetration of photovoltaic (PV) in distribution network (DN), a probabilistic optimal scheduling (POS) method for DN with photovoltaic-storage system (PSS) is proposed. A day-ahead POS model for DN considering the chance constraint of node voltage is developed to minimize the expected operation cost. In this model, the point of common coupling (PCC) of the photovoltaic-storage system is regarded as the QV-type node, of which the reactive power and voltage can be regulated. A verified catastrophic genetic algorithm and a probabilistic power flow (PPF) calculation method considering the QV-type nodes is proposed to solve the model. The simulation results on IEEE 33-bus test system demonstrate that the proposed method is more effective on reducing the risk of voltage violation and suppressing the voltage fluctuation than the existing method.
