| 摘要: |
| 为对偏远地区的含有抽水蓄能、梯级水电、光伏电站联合运行的多能发电系统进行互补式经济优化，搭建多乡镇级用电体之间的日前电量共享协调优化模型，通过区域运营商对构成乡镇联合体的各用电体进行协调管控，实现用电计划的经济高效制定。通过调用抽水蓄能进一步平滑水光出力波动，对乡镇级用电体、区域电网与主网之间的能量流动进行优化，并按参与共享的乡镇对应的贡献函数进行利益最优分配。实际算例分析验证了所提模型与方法的有效性。 |

| Abstract: |
| In order to carry out complementary economic optimization for multi-energy power generation system with pumped storage, cascaded hydropower and photovoltaic power stations in remote areas, a day-ahead coordinated optimal model of electric energy sharing among multiple township level power consumers is built, each power consumer in township consortium is managed and controlled harmoniously by the regional operators to realize economic and efficient formulation of power consumption plan. The pumped storage is used to further smooth the fluctuation of hydropower and photovoltaic power, the energy flow among township level power consumers, regional grid and main grid is optimized, and the benefit is allocated optimally according to the contribution function of township participating in sharing. Practical case analysis verifies the effectiveness of the proposed model and method. |
