Optimization Strategy for Electricity Retailer's Day-Ahead Bidding in the Electricity Spot Market Based on Improved CVaR

中文摘要英文摘要

在电力现货市场环境下,售电公司需要面向市场电价及用户负荷的双重不确定性,在日前申报的环节易造成额外购电成本.然而现有基于条件风险价值(conditional value at risk,CVaR)等随机优化方法的购电方案与风险管理策略中存在等概率缩减关键场景与主观进行置信度选值的问题,为此基于传统的中性风险模型及CVaR优化模型,引入基于K-means的场景聚类缩减方法,提出基于外推内插法的置信度选值优化方法,综合形成改进CVaR的售电公司日前申…查看全部>>

In the electricity spot market,electricity retailers face dual uncertainties that arise from market electricity prices and user loads.The day-ahead bidding process can incur additional purchasing costs owing to these uncertainties.However,existing stochastic optimization methods for electricity purchasing strategies and risk management,such as the conditional value at risk(CVaR),suffer from problems related to equiprobable reduction in key scenarios and subj…查看全部>>
