中文摘要: 为了研究电力市场环境下发电量在发电权交易市场中的分配比例问题,以条件风险价值(CVaR)为风险计量指标,把发电权交易市场分配的电量作为一种无风险资产,建立了带有CVaR约束的期望收益最大化的投标组合模型,讨论发电商的单期发电权交易量分配策略。仿真结果显示,发电权交易的引入,可以使发电商在获得更大收益的同时,规避其他市场中可能存在的风险。该算法对于发电商参与发电权交易具有一定的参考价值和指导作用。
Abstract:In order to determine the generation rights share in the electricity market,an allocation strategy of the single-period generation rights trade was discussed. Taking the conditional value at risk (CVaR) as a risk measurement index and the allocated generation rights a riskless asset, a combined bidding model, was built with CVaR constrained condition, to maximize the expected revenue rate. Simulation results showed that with the introduction of generation rights trade power producers can gain more profit and evade risks in other markets. Power producers can use the proposed algorithm as a reference for trading generation rights.
