| 随着新能源发电占比的逐步提升，电力系统消纳新能源发电的难度和压力增大，电网的频率和电压稳定性面临巨大挑战。通过在电网中配置电池储能系统，不仅可以提升新能源的消纳能力，还可以提升系统频率和电压的支撑能力。因此，研究电池储能系统优化规划方法，考虑储能在电力系统正常运行时用于新能源消纳，在紧急情况下对频率和电压进行快速支撑，从而提高储能利用率，降低系统成本。建立了考虑新能源消纳的电池储能系统协同规划模型，可得到输电网中集中式电池储能系统和配电网中分布式电池储能系统的选址定容结果。提出了一种兼顾频率和电压支撑的电池储能系统规划方法，分别对储能位置、无功功率容量、有功功率容量和能量容量进行优化规划。综合考虑储能的多重功能，构建其支撑系统调频调压的约束，建立了兼顾新能源消纳与频率电压支撑的电池储能系统优化规划模型，得到电池储能系统的最终选址定容结果。基于IEEE 24节点输电网和IEEE 33节点配电网设计算例系统进行仿真分析，验证了所提方法的有效性。 |

| Abstract: |
| With the gradual increase of renewable energy power generation proportion, it is more difficult and stressful for the power system to absorb renewable energy power generation, and the frequency and voltage stability of the power grid are facing great challenges. Battery energy storage system(BESS) can enhance both the renewable energy consumption and the frequency and voltage supporting capability. Therefore, for improving energy storage utilization and reducing system cost, the optimal method of BESS location and sizing is studied with the consideration of using BESS for renewable energy consumption under normal conditions and using BESS for frequency and voltage support under emergency conditions. A collaborative planning model considering renewable energy consumption is built to optimize the location and sizing of centralized BESSs in transmission network and distributed BESSs in distribution network. A planning method that accounts for frequency and voltage support is proposed to respectively optimize BESS location, reactive power capacity, active power capacity and energy capacity. The BESS planning model considering multiple functions of the renewable energy consumption and the frequency and voltage support is established by constructing reserve constraints for frequency and voltage support, so as to determine the final location and capacity of BESS. Simulation analysis is conducted based on the IEEE 24-bus transmission network and the IEEE 33-bus distribution network to verify the effectiveness of the proposed method. |
