【摘要】 该文给出了在寡占的电力市场中,各电厂在已知市场电力反需求曲线,而不知其它电厂电力生产成本的情况下,各发电厂为了获得最大利润而对发电机组的出力进行优化的具有约束条件的古诺模型。在电厂的收益是凹函数并求极大值的情况下,利用了寻找优化函数的库恩-塔克点(K-T点)及各电厂机组的反应函数方程组的方法求取了具有限制条件下的电厂机组出力的期望古诺均衡解。文中例子证明了该文方法的有效性,该方法可以作为电厂优化资源、制定决策的有力的工具。更多还原

【Abstract】 Assuming each generation company knows the market inverse demand function but does not know his rivals?operation costs, a Cournot model in which each generation company optimizes its generation unit output is presented in this paper in order to obtain the maximal benefit in oligopoly electricity market. If generation company抯 payoff function is concave and needs to be maximized, we can obtain the expected Cournot equilibrium state with technical constraints using the method of searching the Kuhn-Tucker points and solve the equation group of reaction functions of generation units. Several examples have been used to demonstrate the models. The test results show the proposed methodology is a useful tool for generation companies to optimize their resource and make their decision.更多还原
