| 摘要: |
| 为以市场化方式激励发电资源的灵活调节能力，提出基于爬坡容量校验的灵活爬坡辅助服务，并将其与市场化调频、深度调峰辅助服务相结合，设计面向高比例风电的现货电能量-辅助服务联合运营机制。对调频服务采用基于综合调频性能均值归一化方法调整机组的容量报价，以体现调频机组性能差异；对深度调峰辅助服务提出基于机组调峰能耗特性的分段报价机制，在充分挖掘机组调峰能力的同时保证其合理收益；对灵活爬坡辅助服务提出与电能量市场耦合的爬坡容量校验机制，通过“反复校验-添加约束”的方式提升系统爬坡能力以跟随风电不确定性引发的净负荷波动。构建现货电能量-辅助服务联合运营的出清模型，并采用等价线性化的方法将非线性模型转换成线性化模型，以提高模型求解效率。采用某省级电网实际数据验证了所提市场机制与出清模型的有效性。 |

| Abstract: |
| In order to stimulate the flexible regulation ability of power generation resources in a market-oriented way, a flexible ramping auxiliary service based on the ramping capacity verification is proposed, and combined with market-oriented frequency regulation and deep peaking auxiliary service, a joint operation mechanism of spot electric energy and auxiliary service for high proportion of wind power is designed. For the frequency regulation service, the mean normalization method based on comprehensive frequency regulation performance is used to adjust the capacity quotation of the unit, which reflects the performance difference of frequency regulation units. For the deep peaking auxiliary service, a segmented quotation mechanism based on the energy consumption characteristics of peaking units is proposed, which fully excavates the peaking capacity of the units while ensures their reasonable benefit. For the flexible ramping auxiliary service, a ramping capacity verification mechanism coupled with the electric energy market is proposed, which improves system ramping capacity through “repeated verification-add constraint” to follow the net load fluctuation caused by wind power uncertainty. A clearing model of joint operation of spot electric energy and auxiliary service is constructed, and the equivalent linearization method is adopted to transform the nonlinear model into a linearized model, which improves the solving efficiency of the model. The effectiveness of the proposed market mechanism and clearing model is verified by the actual data of a provincial system. |
