China's renewable energy continues to develop rapidly with increasing installed power generation capacity, with solar photovoltaic (PV) power becoming the main source of newly installed capacity. With the rapid growth of PV power generation, the problem of PV curtailment caused by various constraints is prominent, hindering the sustainable development of the PV industry. It is urgent to study the PV accommodation ability under large-scale photovoltaic power integration to guide the planning and allocation of PV power generation. This paper proposes an evaluation method of PV power generation accommodation based on sequential operation simulation. With PV power output sequence reconstruction technology, power system detailed network topology, and transmission constraints modeling technique, the PV accommodation ability of the power system can be quantitatively evaluated under the background of high proportion PV power generation integrated to the power system. Taking the planned power grid of Shandong Province in 2025 as an example, the PV accommodation ability is evaluated with the proposed method. The results show that when the installed PV power capacity expands to twice the planned installed capacity, the curtailment of PV power generation will remain at a reasonable level.
