The invention discloses a technology strategy assessment method for improving distributed photovoltaic admitting ability of a power distribution network. The method comprises the steps that under thecondition that no technology strategy is implemented, photovoltaic generating capacity of 8,760 hours in a whole year as well as photovoltaic capacity permeability and energy permeability are calculated, and initial power distribution network maximum distributed photovoltaic admitting capacity (P<0>) is determined; and changes of the distributed photovoltaic admitting capacity of the power distribution network under the condition that different technology strategies k are implemented are determined. According to the technology strategy assessment method for improving the distributed photovoltaic admitting ability of the power distribution network, a permitted load rate lower limit is used as a constraint condition, the method of utilizing a load curve and the photovoltaic generating capacity of 8,760 hours to perform prefectural region photovoltaic admitting ability research is proposed, the photovoltaic admitting ability of the power distribution network is comprehensively measured through the capacity permeability, the energy permeability and other concepts, and the changes of the improved photovoltaic admitting ability of the power distribution network under different technology strategies are analyzed and acquired.
