摘要：

To offer reasonable foundation for the planning of grid-connection of distributed photovoltaic (PV) generations, the mathematical models for voltage deviation and voltage fluctuation caused by various distributions of loads and PV generations are established. Taking the maximum upper deviation of voltage and the maximum voltage fluctuation caused by distributed PV generations and the maximum lower voltage deviation caused by the load only when the PV generation does not exist as constraints, the capacity range of allowed grid-connected distributed PV generations, by which the demand on voltage quality can be met under six distribution conditions of load and distributed PV generations along the feeder, is derived. Taking typical parameters of urban distribution network and those of rural distribution network for example, the proposed method is analyzed and illustrated, results of the analysis show that the proposed method is feasible, and using the proposed method the allowed grid-connected capacity range of distributed PV generations can be determined. ©, 2015, Power System Technology Press.
