摘要:
目的 针对微电网的低碳转型,提出一种电-氢混合储能微电网的优化调度方法,以解决不同商业模式下的调度难题。 方法 首先,建立了包含电-氢混合储能的微电网数学模型,并基于多方合作供能和多方独立供能2种典型商业模式,构建了相应的多目标优化调度模型及其约束条件。然后,引入增强的非支配排序遗传算法II (non-dominated sorting genetic algorithm II,NSGA-II),将其与方差拥挤度计算方法和正态分布交叉算子相结合,以提高优化效率和求解精度。最后,结合东南沿海某地运行的电-氢混合储能微电网系统进行仿真实验,以验证所提方法的有效性。 结果 与优化前相比,多方合作供能商业模式的经济性提升约4.1%,弃风弃光率降低约19%,年度碳排放量减少约47.42 t。 结论 多方合作供能商业模式更符合当前我国电力市场的基本情况,且优化后的系统性能显著提高。所提优化调度方法能够有效支持电-氢混合储能微电网在不同商业模式下实现低碳转型。
