摘要(Abstract):
针对配电网能源市场交易中双线性项非凸且求解精度差等问题,提出基于自适应步长的McCormick包络方法;该方法利用McCormick包络方法松弛双线性项,实现双线性项的线性化处理,采用边界收紧方法迭代收紧双线性项中变量的边界,并基于迭代梯度结果更新步长,在已知可行解基础上,迭代添加原目标函数的上界约束,进一步提升上层模型松弛后的求解质量;将该方法应用于双层能源市场交易模型,对零售商与微电网交易电价引导下的多微电网能源交易运营进行仿真。结果表明,与定步长的McCormick包络方法相比,基于自适应步长的McCormick包络方法实现了配电网侧含双线性项双层模型的有效求解,显著提升交易电价平均值和边界值场景下含双线性项双层模型的求解精度。
