摘　　要：为研究购电商成本最小化的最优电力备用容量电价及发电商利润最大的最优电力备用合约容量,基于随机两层规划,构建了双定价机制下的电力备用合约购电模型,应用Stackelberg博弈理论求解。数值算例分析了单位缺电损失、电力需求方差对最优策略的影响,并进一步探讨了在发电商经济行为存在相互影响的情况下,购电商与发电商最优策略的变化。Based on stochastic two-level programming,electric reserve contract purchase model based dual pricing mechanism is built to study optimal electricity reserve capacity pricing with minimization costs of electric buyer and the optimal electricity reserve contract capacity with maximization profits of generating company.Then Stackelberg game theory is applied to solve the model.The effects of unit shortage loss and electricity demand variance on the optimal strategies are studied with numerical examples.Moreover,optimal strategies are further investigated under considering economic behavior of generators.
