| 摘要: |
| 随着新能源发电量占比的提高，新能源发电量季节性波动引起的年度电力电量平衡问题更加明显。建立年度发电计划模型，提出一种典型时段校核方法；在年度发电计划制定的过程中引入季节性储能设备，建立季节性储氢模型和考虑水头位置的季节性抽水蓄能线性化模型；为了应对新能源出力的不确定性，提出考虑时段校核和季节性储能的年度发电计划三阶段建模方法。算例结果验证了所提模型的有效性。 |

| Abstract: |
| With the increase of ratio of renewable energy generation, the annual power and electricity ba-lance problem caused by seasonal fluctuation of renewable energy generation becomes more obvious. An annual generation plan model is built, and a typical periodic verification method is proposed. The seasonal energy storage devices are introduced in the process of making annual generation plan, a seasonal hydrogen storage model and a linearized model of seasonal pumped storage considering the water head position are built. In order to deal with the uncertainty of renewable energy output, a three-stage modeling method for annual generation plan is proposed considering periodic verification and seasonal energy storage. The effectiveness of the proposed model is verified by example results. |
