摘　　要：推进分布式光伏规模化并网是实现“碳达峰·碳中和”目标和构建新型电力系统的重要举措。基于此背景探讨面向新型电力系统的分布式光伏规模化并网运行关键技术。首先,归纳并阐述分布式光伏发展现状、并网方式及运行模式,分析大规模分布式光伏接入给电网调度运行带来的挑战。其次,面对上述挑战,从信息集成、监测预测、平衡调度、聚合控制等视角提出系统调度运行关键技术,助力电网调控模式转型升级。然后,考虑实际工程需求,构思满足电网安全稳定运行的分布式光伏技术标准体系,以期促使分布式光伏“可观可测、可调可控、友好互动”。最后,调研并梳理国外分布式光伏规模化并网运行先进经验,并对我国分布式光伏并网协同探索、运行服务支持及市场交易参与等课题提出建议。Promoting the large scale grid connection of distributed photovoltaic(PV)is an important measure to achieve the goal of"carbon peaking and carbon neutrality"and to construct the new-type power system.Based on this background,this paper discusses the key technologies for the large-scale grid-connected operation of the distributed PV for the new-type power system.Firstly,the development status,the grid-connected modes,and the operation modes of the distributed PV are summarized and elaborated,and the challenges brought by the large-scale distributed PV access to the power grid dispatching and operation are analyzed.Secondly,in the face of the above challenges,the key technologies for the system scheduling and operation are discussed from the perspectives of information integration,monitoring and prediction,balanced dispatching,and aggregation controlling,in order to assist in the transformation and upgrading of the power grid regulation modes.Then,considering the actual engineering needs,a distributed PV technology standard system that meets the safe and stable operation of the power grid is conceived,with a view to promoting the distributed PV to be"observable,measurable,schedulable,controllable,and friendly interactable".Finally,the advanced experiences of the large-scale grid-connected operation of the distributed PV in some foreign countries are investigated and sorted out,and suggestions on the topics of the distributed PV in China,such as grid-connection collaboration exploration,operation service support and market transaction participation,are made.
