A novel conjectured supply function equilibrium (CSFE) based model for GenCos’ strategic behaviors and their interactions in electricity spot market is introduced.

The conditions of linear supply functions and existence an d uniqueness of market equilibrium are discussed. It is also shown that the proposed model can be used to apply in the market with inelastic electricity demand, and to construct piece-wise supply functions for generation firms easily.提出了一種新的基于微增響應的猜測供給函數均衡 (CSFE)模型 ,用于構造電力市場中發電公司的策略行為及其相互作用 ,比常用的Cournot模型更為客觀地反映了發電公司潛在的市場力。根據供給函數均衡理論 ,提出一種通用的發電公司優化供給曲線模型 ,分析了優化供給曲線為線性的條件 ,并得出如供給曲線為線性則可以惟一確定市場均衡解。通過在IEEE 6機 30母線系統的仿真 ,說明文中模型可以適用于需求無彈性的電力市場分析 ,并易于構造分段線性的發電公司優化供給曲線。
