摘　　要：配网侧分布式资源的规模化发展加大了配网安全可靠供电保障难度。合理规划自治单元能以最小经济成本提升自治单元灵活性、供电安全可靠性以及消纳能力。然而现有的规划方法大多只考虑供电可靠性和经济性约束,未考虑资源相关性、调控模式以及电力市场因素,造成规划结果冗余及资源浪费。从自治单元的物理范围、容量规划影响因素、建模方法及求解算法4个方面进行综述分析,明晰自治单元的物理含义,分析源荷随机不确定性及相关性、调控模式、电力市场政策等因素对自治单元容量规划的影响,讨论考虑多因素的自治单元建模方法,比较不同规划求解算法的适用条件。最后,总结当前自治单元容量规划的不足,并提出相应建议及展望。The development of distributed power generation,new energy storage,and adjustable load on the distribution network side increased the difficulty of ensuring secure and reliable power supply.Rational planning of autonomous units can enhance flexibility,power supply security,and ability to integrate energy at the minimum economic cost.However,existing planning methods mostly consider constraints of power supply reliability and economic efficiency,without considering resource relevance,control modes,and electricity market factors,resulting in redundant planning results and resource waste.This paper reviewed and analyzed the physical scope of autonomous units,influencing factors of capacity planning,modeling methods and solving algorithms,clarifies the physical meaning of autonomous units,analyzes the influence of source-load random uncertainty and correlation,regulation mode,electricity market policy and other factors on autonomous unit capacity planning,discusses the autonomous unit modeling method considering multiple factors,and compares the applicable conditions of different solving algorithms.Finally,the shortcomings of the current autonomous unit capacity planning were summarized,and corresponding suggestions and prospects were proposed.This work is supported by Science and Technology Project of SGCC(Research on Synergistic Optimization and Control Technology for High Proportion of Distributed Photovoltaic Integration into County-level Power Grids,No.52018K220015).
