| 摘要: |
| 从促进清洁能源大范围消纳的视角，在全国统一电力市场格局下，计及跨省输电通道“动态”稳定限额机会约束建立了水电外送消纳弃水风险管理模型。首先，构建了跨省输电通道动态稳定限额数学表达式，实现了稳定限额管理从“静态”到“动态”的转变。同时借鉴半绝对离差的概念建立了弃水风险评估指标，实现了弃水评估从确定性到不确定性的扩展。然后，提出了弃水风险管理理念，在随机规划框架内，在月度市场计及跨省输电通道动态稳定限额，建立了省级电网水电外送消纳弃水风险管控模型，实现了弃水风险的有效管理。随后，在重点给出跨省输电通道动态稳定限额处理技巧基础上，采用内嵌Monte-Carlo模拟技术的多目标遗传算法求解所建模型。最后，以西藏电网为例对上述工作的有效性给予了验证，并探讨了所做研究的普适性。 |

| Abstract: |
| From the perspective of promoting large-range accommodation of clean energy, under the national unified power market, a risk management and control model of accommodation and water discharge of transferring hydropower is developed in this paper. The model takes a dynamic stability limit of cross-provincial transmission channel as an opportunity constraint. First, a mathematical expression about the cross-provincial transmission dynamic stability limit is constructed, thus it is realized that the management of stability limits changes from static state to dynamic state. At the same time, the concept of semi absolute deviation is used to establish the risk assessment index of water discharge, thus it is realized that deterministic assessment extends to uncertainty assessment. Then, based on the framework of stochastic programming and the proposed concept of risk management of water discharge, and the risk management and control model of accommodation and water discharge of provincial power grid is established in monthly market, so as to control the risk of water discharge effectively. After using some techniques to deal with the dynamic stability limit of the cross-provincial transmission channel, a multi objective genetic algorithm with embedded Monte-Carlo simulation technology is proposed to solve the model. Finally, taking Tibet power grid as an example, the validity of the above work is verified, and the universality of the research is discussed.
