在本文中，提出了一个分层的协调充电框架PEVs跨多个聚合器。首先，每个聚合器根据客户充电要求和当地Transformer容量限制计算其聚合充电负载边界。与聚合器的负载边界，线性优化模型，然后解决了在配电系统运营商（DSO）的水平，以生成每个聚合器的首选充电曲线。最后，每个聚合器基于快速启发式算法智能地分配由DSO建议的充电功率。四个聚合器遵循不同的收费策略进行了案例研究。仿真结果表明，该充电协调框架成功地实现了电力成本最小化和系统峰值负荷控制。此外，考虑到聚合器的部分利润可能会受到损害，参与收费协调，一个简单而明确的补偿机制的聚合器设计。
In this paper, a hierarchical coordinated charging framework for PEVs across multiple aggregators is proposed. First, each aggregator computes its aggregate charging load boundaries based on customer charging requirements and local transformer capacity limits. With the load boundaries of aggregators, a linear optimization model is then solved at the distribution system operator (DSO) level to generate the preferred charging curve for each aggregator. Finally, each aggregator intelligently allocates the charging power suggested by the DSO based on a fast heuristic algorithm. Case studies on four aggregators following different charging strategies are carried out. Simulation results indicate this charging coordination framework successfully achieves electricity cost minimization and system peak load controlling. Moreover, considering that part of profits of aggregators might be compromised by participating in charging coordination, a simple but clear compensation mechanism for aggregators is designed.
