| 摘要: |
| 具有灵活双向调节和零碳特性的含制氢海上风电系统是实现风电完全消纳及受端电网低碳经济运行的有效途径。针对海上风电场组网后馈入陆上电网形成的交直流电力系统，提出了一种计及含制氢海上风电多点馈入可调度域的交直流电力系统低碳经济运行策略。基于计算几何理论，构建含制氢海上风电并网点的多时段可调度域，实现含制氢海上风电可调度能力的可视化。建立含制氢海上风电多时段可调度域的分布鲁棒低碳经济运行模型，并利用可调度域降低模型求解复杂度和保守性。对含11节点海上电网的IEEE 30节点交直流电力系统进行仿真。结果表明所提方法能够使系统的运行成本降低17.09 %，弃风率降低28.8 %，具有显著的低碳经济效益。 |

| Abstract: |
| The offshore wind power system with hydrogen production, which has flexible bidirectional regulation and zero carbon characteristics, is an effective way to realize the complete absorption of wind power and the low-carbon economic operation of the receiving-end power grid. In view of the AC/DC power system formed by the offshore wind farms networking and feeding into the onshore power grid, a low carbon economic operation strategy is proposed for the AC/DC power system based on the dispatchable domain for offshore wind power multipoint feeding and hydrogen production. Based on the computational geometry theory, the multi-period dispatchable domain for different grid connection points of offshore wind farm with hydrogen production is constructed to realize the visualization of the dispatchable capability of the offshore wind farm. A distributionally robust low-carbon economic operation model with multi-period dispatchable domain of offshore wind power with hydrogen production is established. And the dispatchable domain is used to reduce the complexity and conservatism of the model solution. The IEEE 30-bus AC/DC power system with 11-bus offshore power grid is simulated. The results show that the proposed method reduces the operating cost by 17.09% and the curtailment rate by 28.8%,and has significant low-carbon economic benefits. |
