This paper proposes an effect orientated approach to enhance the short-term voltage stability for wind-penetrated power systems. The low system stability with high uncertain renewable energy is addressed by coordination of network and non-network solutions, i.e., STATCOM placement and UVLS respectively in this paper. The proposed model considers the uncertainties of power systems, including operating points load dynamics and multiple contingencies. Unlike other methods that try to minimize the cost, the proposed method aims to maximize the voltage stability enhancement with a fixed cost. The high computing burden is alleviated by a net flow-based scenario reduction algorithm. Compared with the conventional approaches, this paper has three major contributions: 1) Device placement is coordinated with demand response. 2) Operating points and type 4 wind turbines are considered. 3) An effect maximizing DP algorithm with a robust scenario reduction method is applied. The effectiveness and efficiency of the proposed method is demonstrated on the New England 39-bus test system.

STATCOM和UVLS的非网络解决方案可增强风力穿透电力系统的电压稳定性

本文提出了一种以效果为导向的方法来增强风电系统的短期电压稳定性。通过网络解决方案和非网络解决方案的协调，即STATCOM放置和UVLS，解决了系统稳定性低，可再生能源不确定性高的问题。所提出的模型考虑了电力系统的不确定性，包括工作点负载动态和多种意外情况。不同于试图最小化成本的其他方法，所提出的方法旨在以固定成本最大化电压稳定性的增强。基于网络流量的场景减少算法可减轻高计算负担。与传统方法相比，本文具有三个主要贡献：1）设备放置与需求响应相协调。2）考虑了工作点和4型风力发电机。3）应用了一种鲁棒的场景减少方法来最大化DP算法的效果。新英格兰39总线测试系统证明了该方法的有效性和效率。
