| 中文摘要: |
| 可再生能源的并网容量逐年扩大，高比例可再生能源接入系统后将对电力系统的运行稳定性带来挑战，故应研究高比例可再生能源并网后的优化调度方法。首先分析了系统的灵活性资源调用成本，其次构建了考虑灵活性资源响应的可再生能源消纳动态优化调度模型，并采用动态最优潮流算法求解，通过考虑源-网-荷-储等多种灵活性资源，研究高比例可再生能源并网后的系统调度运行情况。最后，通过IEEE 39 节点系统对提出的优化调度方法进行了验证和测算。算例结果表明通过电力系统中的灵活性资源响应，可以提高可再生能源的消纳电量，并降低系统的失负荷风险，提高电力系统的安全运行水平。 |

| The capacity of renewable energy grid connected is expanding year by year. A high proportion of renewable energy will challenge the operational stability of power system. Firstly, the invoking cost of flexible resource is analyzed. Therefore, the optimized scheduling method for high proportion of renewable energy should be studied. The dynamic optimal scheduling model of renewable electricity accommodation is proposed and solved with the algorithm of dynamic optimal power flow. Finally, the dispatch method proposed is verified by the IEEE 39 bus network. The results show that the accommodation electricity of renewable energy and the safe operation level of power system can be improved through the response of flexible resources. |
