在本文中，我们提出了一种分层的交互控制架构，它将高层的市场交易与低层的区域间和单元级控制相结合。介绍了这种架构的一个模型，其在一次、二次和三次层级具有动态特性。以在可再生能源和负荷存在不确定性的情况下利用资源的最优分配确保频率调节为目标，提出了一种分层控制方法。在所有三个时间尺度都存在不确定性的情况下，确立了整个系统的全局渐近稳定性。使用IEEE 30节点以及实际规模的实例仿真来验证该方法，结果表明所提出的控制架构有可能降低备用成本并增加社会福利。
In this paper, we propose a hierarchical transactive control architecture that combines market transactions at the higher levels with inter-area and unit-level control at the lower levels. A model of this architecture is introduced, with dynamics at primary, secondary, and tertiary levels. With a goal of ensuring frequency regulation using optimal allocation of resources in the presence of uncertainties in renewables and load, a hierarchical control methodology is presented. Global asymptotic stability of the overall system is established in the presence of uncertainties at all three time-scales. An IEEE 30-bus as well as simulations of practical examples of realistic sizes are used to validate the approach where it is shown that the proposed control architecture has the potential to reduce cost of reserves and to increase social welfare.
