| 摘要: |
| 开展保底电网的研究是落实国家能源局关于坚强局部电网规划建设实施方案的重要举措，储能技术的应用可完善严重故障下保底电网按局部电网独立运行的能力。针对这一问题，提出了一种电化学储能在保底变电站中的配置方案与控制策略。首先，探讨了电化学储能在保底变电站中的接入方式，并根据灾害期间的供电负荷发展水平制定了电化学储能的容量配置方案；然后，提出了电流补偿方法、相位补偿方法以及相位预同步方法等，以实现保底变电站在并网转孤网、孤网转并网运行期间的平滑切换，完善了储能系统的抗灾控制策略；最后，以广东沿海某地区电网的保底变电站为例仿真验证了所提方法的有效性。 |

| Abstract: |
| The research on security power grid is an important measure to implement the plan of the National Energy Administration on strong regional power grid planning and construction. The application of energy storage technology can improve the ability of security power grid to operate independently according to the regional power grid in case of severe faults. In order to solve this problem, the configuration scheme and control strategy of electrochemical energy storage in security power substation are proposed. Firstly, the access modes of electrochemical energy storage in security power substation are discussed, and the capacity configuration scheme of electrochemical energy storage is formulated according to the development level of power supply load during the disasters. Then, the current compensation method, the phase compensation method and the phase pre-synchronization method are proposed to realize the smooth switching of security power substation during the operation periods of grid-connected state to islanded state and islanded state to grid-connected state, thus improving the anti-disaster control strategy of energy storage system. Finally, the effectiveness of the proposed method is verified by taking the security power substation of a coastal power grid in Guangdong province as an example. |
