摘要(Abstract):
在我国新一轮电力市场改革背景下,为了进一步提升电力现货市场的资源配置能力,提出了市场环境下衔接日前出清环节的多日机组组合优化策略。提出的多日机组组合方法作为日前市场出清的辅助手段,在充分考虑了未来几日电网负荷特性变化情况的前提下,采用市场化的方式,提前多日对系统发电资源的运行方式进行了统筹预安排。进一步,将多日机组组合的优化结果设置为日前市场出清模型的边界条件,实现了多日机组组合与日前出清环节的有效衔接,使得日前市场的出清计算结果更加合理,同时解决了燃煤机组由于开机准备时间长而无法在日前市场中新增启动的问题。最后,采用我国某省的实际电网数据进行算例研究,验证了所提出的多日机组组合优化策略的有效性。
