| 摘要: |
| 储能功率的可控性为含有随机波动电源的配电网供电能力提升提供了新的解决方法。考虑了分布式电源的波动性和间歇性，针对含DG的配电网供电能力，采用模糊机会目标理论。以潮流分布、储能电站运行参数和电量作为约束条件，建立了储能功率优化模型，提出了多级多目标的储能功率的动态优化方法，并对储能功率进行综合优化，以提升配电网的供电能力。算例验证了所提方法的有效性和客观性。 |

| Abstract: |
| The controllability of energy storage system provides a new solution to improve power supply capability with random fluctuation power source. The research takes DG’s volatility and intermittent into account. According to the fuzzy goal theory, the power supply capability is mainly analyzed. To improve the power supply capability, load flow distribution, energy storage substation operating parameters, and electric quantity are taken as constraint conditions for building optimized model for energy storage power and a multi-level & multi-objective dynamic optimization method to achieve energy storage power modification is proposed. Calculation results of cases confirm the effectiveness and objectivity of the proposed method. |
