| 摘要: |
| 随着可再生能源渗透率的提高，高比例可再生能源并网导致的电力系统灵活性资源短缺问题日渐凸现。基于电力全成本构建了包含灵活调节服务的双层优化模型，利用KKT(Karush-Kuhn-Tucher)条件将下层模型转化为上层模型的约束，应用大M法对问题进行线性化处理。对比了传统出清模式与计及灵活调节服务模式对发电商收益的影响，发现引入灵活调节服务可在增强电力系统可靠性的同时降低系统运营商总成本，同时可提高系统运行的经济性。此外，对灵活调节服务价格与碳排放价格的敏感性分析表明：系统运营商成本和发电商收益均与碳排放价格呈正相关关系，且当灵活调节服务价格超过中断负荷的单位成本时，将导致电力市场出清机制失效。 |

| Abstract: |
| With the increase of renewable energy penetration, the shortage of flexibility resources in power systems has become more prominent due to large-scale renewable integration. A bi-level optimization model incorporating flexible regulation services is constructed based on the concept of full cost of electricity. The lower-level model is transformed into constraints of the upper-level model using the KKT (Karush-Kuhn-Tucher) condition, and the problem is linearized by applying the big-M method. The impacts of the traditional clearing model and the model accounting for flexible regulation services on the revenue of power generators are compared, and it is found that introducing flexible regulation services can reduce the total cost for system operators, enhance power system security, and improve the economy of system operation. In addition, a sensitivity analysis of the flexible regulation service prices and the carbon emission prices shows that both operator cost and generator revenue are positively correlated with carbon emission prices. Moreover, when the price of flexible regulation services exceeds the unit cost of interrupted load, the electricity market clearing mechanism fails. |
