摘要

可再生能源的高度普及给电力系统的频率稳定性带来了挑战，储能系统将被广泛安装以提供频率支持，这就提出了如何在发电调度中协调传统能源与储能设备的问题。本文提出了一种频率约束的源-网-负荷-存储协调调度模型，该模型可以用混合整数二次规划(MIQP)问题来表示。对改进的IEEE 24总线系统的实例分析表明，该调度方法在保证频率安全的同时，提高了电力系统的经济性。

Frequency Constrained Source-Grid-Load-Storage Coordination Dispatch

The high penetration of renewable energy sources (RESs) brings challenges to maintain the frequency stability of power systems, and energy storage systems (ESSs) will be widely installed to provide frequency supports, which raises the concern: how to coordinate the conventional sources with storage devices in generation dispatch. This paper proposes a frequency constrained source-grid-load-storage coordination dispatch model to coordinate various generation sources, which can be formulated with a mixed-integer quadratic programming (MIQP) problem. Case studies on modified IEEE 24-bus system show that our schedule method can guarantee the frequency security while improving the economics of the power systems.
