Abstract

Frequency control is essential to maintain the stability and reliability of power systems. Traditionally, generation side controllers have been used to stabilize the system frequency upon contingencies; however, they incur high operational cost. Enabling demand response in next generation smart grids is thus a promising alternative to reduce the power system dependency on expensive controllers. In particular, demand response of distributed electric vehicles (EVs) via controlled charging/discharging power from/to the grid can be an effective method to help stabilize the system frequency. In this paper, we propose a new distributed frequency control algorithm for EVs with randomized responses and characterize its performance in a large-scale dynamic power system in terms of the mean of the system frequency over time, the mean frequency recovery time, and the expected number of responded EVs upon a contingency. Finally, we validate our analysis via simulations under a practical power system setup.

随机响应电动汽车在智能电网中的分布式频率控制

频率控制是维持电力系统稳定可靠运行的关键。传统上，发电侧控制器被用于在突发事件时稳定系统频率;然而，它们产生了很高的运营成本。因此，在下一代智能电网中实现需求响应是减少电力系统对昂贵控制器依赖的一个有希望的替代方案。特别是，通过控制向电网的充电/放电功率来响应分布式电动汽车(ev)的需求，可以成为帮助稳定系统频率的有效方法。本文提出了一种针对随机响应电动汽车的分布式频率控制算法，并从系统频率随时间的平均值、平均频率恢复时间和意外情况下响应电动汽车的预期数量等方面描述了该算法在大型动态电力系统中的性能。最后，在实际的电力系统设置下，通过仿真验证了我们的分析。
