| 摘要: |
| 针对负荷侧电池储能电站（BESS）平抑由能源不确定性和负荷不确定性带来的计划外功率波动的功能定位，并考虑BESS实际运行情况及新型蓄电池自身运行约束，以钠硫电池为例，建立了负荷侧新型BESS动态功能运行、分析与评价的模型，针对电力系统中带有可再生能源的地区负荷的2种构成，即混合组网和独立组网，分别提出了负荷侧BESS优化调度策略：协调调度和自主运行模式。算例证明了该模型在各运行方式下的有效性，通过对算例结果的扩展计算，进一步讨论了系统中BESS的最佳配置数量及最佳联络线协议时长的问题。 |

| Abstract: |
| The BESS（Battery Energy Storage System） at demand side is applied to suppress the power fluctuation caused by the uncertainties of power source and load. With NaS battery as an example，a dynamic model is established to analyze and assess its dynamic duty，which considers its actual operating conditions and the operational constraints of new-type battery. The coordinated operating strategy of demand-side BESS is proposed for the grid-connected regional power network with renewable energy while the stand-alone operating strategy is for the isolated one. Case study proves the validity of proposed model. The optimal BESS configuration and tieline pact is further discussed. |
