摘要
在配电侧开放的市场中,供电公司和大用户都拥有更多选择的权力。本文通过基于动态条件风险价值(DCVaR)的方法获得了供电公司的购买电量比例。针对配电网交易中存在随机量的特征,通过建立随机二层优化的数学模型将供电公司和各大用户的利益进行整合。仿真结果表明,用二层规划法确定的供电公司最优销售电价和大用户相应的最优购电量分配比仅站在某一方的角度确定的结果更加合理,并且二层优化模型体现了交易双方的博弈过程,具有实际辅助决策意义。
In the opening distribution market,the distribution utility and large consumers have more options.At first,purchasing power ratio of the distribution utility is obtained based on dynamic conditional value at risk（DCVaR） measurement.Then,because of random in trading,a stochastic bilevel programming model is established in order to integrate benefits of the distribution utility with profits of large consumers.The simulation result shows that the optimal sale price of the distribution utility and purchasing power distribution of large consumers obtained on both sides are more rational than that on one side.The bilevel programming approach could embody gaming process between the distribution utility and large consumers.The presented model can help decision-making in actual application.
