摘要
为分析电力市场下流域梯级水电站的联盟策略,结合梯级水电站自身特点与发电约束,剖析流域上不同投资主体水电站的潜在联盟结构,建立联盟博弈模型,并采用改进的灰色GM(1,1)模型预测市场中对手的报价,以解决博弈的不完全信息问题。以某梯级水电站为例,探讨了梯级水电站不同联盟结构的形成条件。结果表明,市场需求弹性系数越高,梯级水电站的结盟偏好越显著。
To analyze the coalition strategy of cascaded hydropower stations in electricity market, a coalition game model with constraints of the hydropower＇s technical and economic characteristics is proposed. Different potential coalition structures of cascaded hydropower stations belonging to different investors are discussed. An improved GM （1,1） grey model is used to predict opponent＇s pricing and solve the incomplete information game problem in electricity market. The coalition forming condition is test on a cascaded power system along a certain river. The results show that a higher de- mand elasticity coefficient implies the more intensive preference of forming cascaded reservoir coalition.
