摘要

新能源装机规模快速增长，但新能源场站在接入节点、接入结构和组织方式上存在多维度差异，导致的并网特性差异尚不明确，是电力系统规划面临的重要难题。采用特征向量中心性方法对可并网节点进行分类，结合不同组织方式与接网结构提炼新能源场站接网典型场景进行仿真，在经济性、可靠性和结算便利性3个维度构建评价指标体系并进行对比分析。结果表明，短接线、受潮流约束影响少的方案经济性较优，建设成本较其他方案可下降3%~12%；在一般节点采用直接接入方案具有较高可靠性，但在极端天气下仍需通过复杂结构增强韧性；当接入主体超过4个时，计量与责任划分趋于复杂，结算便利性明显下降。研究结果可为电力系统进行精细化规划提供理论依据。

Abstract

At present

the installed capacity of renewable energy in China is growing rapidly. However

differences of renewable energy stations in access nodes

grid connection structures

and organizational modes lead to unclear grid-integration characteristics

posing a critical challenge to power system planning. This paper uses the eigenvector centrality method to classify grid-accessible nodes

and combines different organizational modes and access structures to build typical access scenarios for simulation. An evaluation index system is established covering economy

reliability

and settlement convenience. Comparative analysis results show that short connections with fewer power flow constraints have better economic performance

with construction costs reduced by 3%~12% compared with alternative schemes. Direct connection at conventional nodes offers high reliability

yet elaborate structures are needed to improve system resilience under extreme weather conditions. In addition

Metering and liability allocation become complicated and settlement convenience declines markedly when the number of access entities exceeds four. This work provides a theoretical references for refined power system planning.
