Flexible AC Transmission System (FACTS) Controllers are useful in improving power system reliability and relieving congestions in power systems, which are particularly important in deregulated electricity markets using locational marginal prices and thus are of national interest. The proposal addresses the development of a common modeling framework suitable for implementing both thyristor-controlled and voltage-sourced converter (VSC) based FACTS Controllers. This common power system model will have the ability to include injected series voltage sources, which can circulate active power with other injected voltage sources, thus expanding the capability of power system models. In this framework, network sensitivities can be readily computed and be used to evaluate the effectiveness of FACTS Controllers for steady-state power transfer and voltage support, and transient power and voltage swings. The proposed research will develop the FACTS Controller models and the sensitivity computation tools. The models and tools will be used in determining the optimal FACTS Controller dispatch for a given power transfer condition, as well as evaluating the maximum transfer capability over a congested transfer path. In interarea-mode damping control design, they will be used in computing the controllability of a FACTS Controller; the observabilities of potential input signals for the controller, and the inner-loop gain limitations of the individual input signals. In addition, the use of the common FACTS Controller model in state estimation will be investigated.

灵活交流输电系统（FACTS）控制器在提高电力系统可靠性和缓解电力系统中的不稳定性方面是有用的，这在使用位置边际价格的放松管制的电力市场中特别重要，因此是国家利益。该建议解决了一个共同的建模框架，适用于实现晶闸管控制和电压源转换器（VSC）为基础的FACTS控制器的发展。该通用电力系统模型将具有包括注入的串联电压源的能力，该注入的串联电压源可以与其他注入的电压源一起循环有功功率，从而扩展电力系统模型的能力。 在这个框架中，网络灵敏度可以很容易地计算，并被用来评估FACTS控制器的稳态功率传输和电压支持，以及瞬态功率和电压摆动的有效性。本研究将发展FACTS控制器模型及灵敏度计算工具。这些模型和工具将用于确定给定功率传输条件下FACTS控制器的最佳分配，以及评估拥塞传输路径上的最大传输能力。控制器的潜在输入信号的可观测性，以及各个输入信号的内环增益限制。此外，使用常见的FACTS控制器模型的状态估计将进行调查。
