本文研究了电力市场竞争模型中的供应函数均衡问题。它通过放宽传统的供给函数连续性假设，引入了理论上的进步，并为高效的计算算法提供了基础。文中考虑了两个特殊的例子。其中一个证明了，当存在无限组不连续均衡时，连续均衡是不可能的。另一个例子证明了在线性供应系统中通过学习收敛到一个线性均衡。讨论了分段线性系统类似收敛的可能性。
The paper deals with the Supply Function Equilibrium (SFE) as a model of competition in electricity markets. It introduces theoretical advancement through relaxing traditional assumptions of continuity of supply functions and provides a foundation for efficient computational algorithms. Two special examples are considered. One demonstrates that continuous equilibrium could be impossible while an infinite set of discontinuous equilibria exists. Another example proves the convergence to a linear equilibrium through learning in linear supply system. A possibility of a similar convergence for piece-wise linear system is being discussed.
