摘要
为了实现配电网的经济高效运行,提出了一种基于两级分层优化的能源存储系统模型预测控制方法。首先提出了一种字典优化方案,通过最小化变压器功率极限限制和飞轮能量损失来定义飞轮功率设定点;然后导出了表示飞轮功率损耗及其最大功率的凸函数,并引入两级分层控制框架,从而处理预测误差和模型精度的方式操作变压器飞轮系统;最后通过仿真和实验结果验证了所提出的能量管理和控制方案在现实条件下提供调峰服务的有效性。
In order to achieve the economic and efficient operation of the distribution network,a two-level hierarchical optimization based energy storage system model predictive control method is proposed.Firstly,a dictionary optimization scheme was proposed to define the flywheel power set point by minimizing the transformer power limit and flywheel energy loss.Then,a convex function representing the flywheel power loss and its maximum power was derived,and a two-level hierarchical control framework was introduced to operate the transformer flywheel system in a way that handles prediction errors and model accuracy.The final simulation and experimental results verified the effectiveness of the proposed energy management and control scheme in providing peak shaving services under real conditions.
