摘要
Abstract
The evaluation of the maximum hosting capacity of distributed photovoltaic(PV)integration into distribution networks is of great guiding significance for the planning and operation of distribution networks.Therefore,a"bottom-up"and"top-down"evaluation model and method for the maximum hosting capacity(MHC)of distributed PV in distribution networks is proposed.Firstly,based on the prediction results of the distributed photovoltaic spatial-temporal distribution,the independent hosting capacity of each transformer and line equipment is assessed using a piecewise exploration method.Then,the independent hosting capacities of various equipment,along with the PV application capacity and the already connected capacity,are aggregated to determine the overall hosting capacity step by step in a"bottom-up"manner.Finally,taking into account the current status of distributed PV(i.e.,PV application capacity and already connected capacity)and its development trend,the overall hosting capacity is decomposed step by step and equipment by equipment in a"top-down"manner.Compared with the evaluation results obtained using the related"top-down"standard method,the proposed method can quickly verify distributed PV integration schemes,facilitating the rational development of distributed PV.关键词
