摘　　要：以利润最大化为目标,考虑容量补偿费用,建立了一个发电投资的Nash-Cournot决策模型,用非线性互补方法和改进的Levenberg-Marquardt算法求出均衡解。算例分析表明,增加容量补偿费可以激励发电商投资,从而保证系统容量的充裕性,且两部制电价的容量补偿方法对于低投资成本、高运行费用的机组投资激励更加有效,计算结果证明了该模型的合理性和算法的有效性。Nash-Cournot model is developed in generation investment in order to maximize the profit. The model has taken the capacity compensation into consideration and is solved by advanced Levenberg-Marquardt algorithm based on the nonlinear complementary approach. The results show that incentive of investment from generation utilities can be achieved by increasing capacity compensation, hence guaranteeing the adequacy of system capacity. Furthermore, the inspiration of the two-step pricing is more effective to the unit that has low investment and high operation cost. The proposed methodology has been proved to be effective.
