摘要: 大规模可再生能源的接入给电网调峰带来了巨大挑战,使得当前调度模式下发电机组均衡地完成其电量进度愈发困难。针对电网的日内调度计划,提出了调峰辅助服务与电量协调优化的日内调度模式,避免调峰服务市场机制与现有调度模式产生冲突。在该调度模式的基础上,建立了调峰辅助服务与电量协调优化的日内安全约束经济调度模型,实现了调峰资源与常规发电资源的协调调用,最优化系统的总调度成本。为了加速求解该调度模型,提出了以识别起作用安全约束为特征的迭代求解算法。最后,通过基于IEEE-30节点系统和实际省级电网的算例分析验证了所提模型方法的有效性、高效性与实用性。

Abstract: The penetration of large-scale renewable energy brings great challenge to power system peak regulation, which makes it more difficult to balance the energy completion processes of different units under the current dispatch mode. Aiming at the intraday dispatch problem, an intraday dispatch mode with coordinative optimization of peak regulation ancillary service and unit energy is proposed, so as to avoid the collision between the peak regulation market mechanism and the current dispatch mode. Based on the proposed mode, the intraday security-constrained economic dispatch model is developed to realize the coordination of peak regulation ancillary service and unit energy as well as minimize the overall dispatch costs. To accelerate the computation of this model, an iterative algorithm featuring identifying the bidding security constraints is derived. Finally, the effectiveness and efficiency of the proposed models and methods are validated by the IEEE 30-bus system and a real-world provincial power system.
