从存储器控制功率和虚拟惯量以获得频率响应

Controlling Power and Virtual Inertia from Storage for Frequency Response

Shuchang Yan

摘要:

如今,由于可再生能源的更多集成,功率不平衡发生得更频繁。储能是一种可以在一个时间充电,在另一个时间释放能量的装置。这一功能使得储能在促进电力系统功率平衡方面得到了广泛的应用。除此功能外,存储器还可以模拟虚拟惯性,以响应系统中的频偏。本文提供了一个广义优化框架来分析当大扰动发生时,如何控制来自存储器的功率和虚拟惯性参与频率响应。采用集中式和分布式模型预测控制相结合的方法,通过实例验证了优化框架的有效性。

英文摘要:

Nowadays, power imbalance happens more frequently due to the more integration of renewable energy sources. Energy storage is a kind of devices that can charge energy at one time and discharge energy at another time. This function makes that storage is widely envolved into promoting power balance of power system. Besides this function, storage can also emulate virtual inertia to respond to frequency deviations in the system. This work provides a generalized optimization framework to analyze how to control power and virtual inertia from storage to participate in frequency response when a large disturbance happens. Centralized and distributed model predictive control is employed here, and case study verifies the effectiveness of our optimization framework.
