摘　　要：在新型电力系统建设背景下,统筹考虑新型储能复合功能及应用场景,并从系统全局角度论证储能规划配置规模以及协调布局是当前面临的重要技术问题。从解决复杂交直流电网新型储能协调规划布局问题角度,提出了系统级新型储能布局规划两阶段法。第一阶段以提升系统新能源消纳能力、确保系统规划投资和运行综合成本最低为优化目标,初步确定系统整体储能配置规模;第二阶段统筹考虑解决新能源汇集区消纳及外送通道输电能力、负荷密集区网络阻塞、系统暂态稳定等问题,优化新型储能安装位置及布点规模,给出方法的相关模型和流程。最后以某省级2025年规划复杂交直流电网为基础,对复合场景下储能配置规模及布局开展案例论证,验证了模型和方法的有效性。In the context of the construction of new power systems,it is an important technical issue to consider the composite func⁃tions and application scenarios of new energy storage,and to demonstrate the planning and configuration scale and coordination of energy storage from the overall perspective of the system.This paper takes the coordination planning and layout of new energy stor⁃age for complex AC and DC power grids as the background,proposes a new system-level energy storage layout planning two-stage method.In the first stage,the optimization goal is to improve the new energy consumption capacity of the system,ensure the lowest overall cost of system planning and comprehensive operating cost,and preliminarily determine the overall energy storage configura⁃tion scale of the system.In the second stage,overall consideration is given to solving the consumption problems of new energy collec⁃tion areas and delivery capacity of external delivery channels,network blockage in load-intensive areas,and system transient stability,the installation location and layout scale of new energy storage is optimized,and relevant models and processes of the method are provided.Finally,based on the complex AC and DC power grid planning of a province in 2025,a case study is carried out on the configuration scale and layout of energy storage in a compound scenario,which verifies the effectiveness of the model and method.
