差价合约下电网公司购电费用最小化的离散优化模型

以购电费用最小化为目标函数,构建了差价合约下电网公司在合约市场、现货市场、备用市场和可中断负荷交易市场上的最优购电模型,并利用启发式算法给出了该模型的求解算法,最后,通过算例分析了差价合约及合约电量比重对电网公司购电费用的影响。

Discrete Optimization Models for Minimizing Grid Company''''s Purchase Power Cost under Contract for Difference

At the aim of minimizing the power grid company's purchasing electric power cost,an optimal model is set up under the contract for difference,which the grid company can buy power in contract,spot, reserve and interruptible load trade markets. An algorithm of this model is given using heuristic approach. At last,the influence on the electric power purchasing cost of the grid company made by contract for difference and the percentage of contract power quantity is analyzed.
