摘要
在不确定的电力现货市场条件下,讨论了发电商和售电商关于长期合约交易与现货交易之间的最佳选择策略方法,提出一种(随机)二层规划理论模型及其求解算法。根据求解结果,发电商可确定适当的合约电价及合约电量,使公司获得最大利润;售电商能对签订多少合约电量和购买多少现货电量做出最佳决策,使公司获得最大效益。最后给出了结论及需进一步研究的问题。
A stochastic bilevel programming model and its algorithm of optimal bidding strategies, between power seller and buyer for contracting arrangements of the long-term contracts and the spot markets transactions under uncertain electricity spot market, is proposed. According to the results of the model, the power seller can decide an appropriate contract price and capacity so that the maximal profit is obtained, the power buyer can select the optimal contract capacity and spot-market capacity in order to achieve their maximum utility. Lastly, the conclusion is given and the further research problems are discussed.
