传统上，系统运营商会将发电成本最小化，将输电视为无源系统。有了智能电网技术，输电网络的拓扑结构可以与发电系统同时优化。这可以通过接通和断开线路，或者通过连续控制线路的导纳来实现。FACTS装置使调整输电线路的导纳成为可能。在这里，我们研究了一种基于供给函数均衡(SFE)的FACTS设备运行的市场设计。我们将与使用FACTS设备相关的可变成本建模为相对额外的损失成本。所有者获得的是他们提供的额外转移能力的市场清算价格。给出了一个简单的两节点两传输线系统的数学模型。结果表明，边际成本函数呈递增趋势，FACTS设备是否是自然垄断尚不清楚。我们的模拟研究表明，可以采用市场机制来运行这些设备。在我们考虑的市场机制下，FACTS设备的所有者可以与发电机一起向市场提出供应报价。市场清算包括确定发电机的节点价格和输电或FACTS设备所有者的基于准入的定价。这样的市场将有利于设备所有者，通过增加社会福利为他们和系统提供收入。
Traditionally system operators would minimize generation cost considering transmission as a passive system. Having the smart grid technology transmission network topology can be optimized simultaneously with the generation system. This can be done either by switching lines on and off, or by continuously controlling the admittance of the lines. FACTS devices make adjustment of a transmission line's admittance possible. Here we study a market design for operation of such FACTS devices based on Supply Function Equilibrium (SFE). We model the variable cost associated with utilization of the FACTS devices as the relative additional cost of losses. The owners are being paid the market clearing price for the additional transfer capacity they provide. The problem is formulated for a simple two-node two-transmission line system. It is shown that the marginal cost functions are increasing and it is not clear that FACTS devices are natural monopoly. Our simulation study shows that a market-mechanism can be employed for operation of the devices. Under the market mechanism that we consider, owners of FACTS devices are permitted make supply offers to the market alongside generators. Market-clearing consists of determining nodal prices for generators and admittance-based pricing for transmission or FACTS device owners. Such a market would be beneficial to the device owners by providing revenue for them and the system by increasing the social welfare.
