| 摘要: |
| 针对大规模DG并网带来的电网调峰及备用容量需求，基于全局协调、分区自治思想，提出多站融合供电系统辅助调峰自律运行调控策略。构建调峰备用等相关技术指标以量化供电区域应具备的“自律能力”。根据供电区域调峰需求，提出多种融合供电区域储能站自律调峰控制策略。为满足主网调峰备用需求并实现供电区域“自律”运行，将储能调峰自律控制策略联合优化配置，建立多站融合供电区域储能站容量优化配置模型。采用鲁棒优化联合端点场景筛选法构建供电区域典型运行场景，利用智能优化算法对模型进行求解。最后，对多站融合典型实施案例进行算例分析，结果证明了所提方法的有效性。 |

| Abstract: |
| Based on the idea of global coordination and regional autonomy, the regulation strategy of a multi-station integrated power supply system for assisting peak regulation and autonomous operation is proposed to meet the demand of power grid peak regulation and reserve capacity with large-scale interconnection of distributed generation. It builds relevant technical indicators such as peak regulation and standby to quantify the "self-discipline ability" that a power supply area should have. According to the demand of peak regulation in a power supply area, a variety of autonomous peak regulation control strategies for an energy storage station in the power supply area are proposed. In order to meet the standby demand of peak regulation in the main network and realize "self-regulated" operation in the power supply area, a self-regulated control strategy of energy storage peak regulation is combined to optimize the configuration. A capacity optimization configuration model of an energy storage station in the multi-station fusion power supply area is established. A robust optimization joint endpoint scenario screening method is used to construct a typical power supply region operation scenario and an intelligent optimization algorithm is used to solve the model. Finally, a typical implementation case of multi-station fusion is analyzed and the results prove the effectiveness of the proposed method.
