The author puts forward a two-period model extending the Tirole's literature, and analyzes the equilibrium in the used durable market under perfect and imperfect information. Moreover, the conclusion shows the important role of information to consumers' behaviors and the equilibrium in the entire market.展开更多
为适应国内电力市场发展,灵活应对电价不确定性,文中以国内电力市场建设现状为基础,重点围绕发电企业在日前市场下的交易展开研究。综合考虑由于日前出清电价存在不确定性而造成的影响以及碳排放权交易成本,构建了在参与日前电能量市场...为适应国内电力市场发展,灵活应对电价不确定性,文中以国内电力市场建设现状为基础,重点围绕发电企业在日前市场下的交易展开研究。综合考虑由于日前出清电价存在不确定性而造成的影响以及碳排放权交易成本,构建了在参与日前电能量市场与辅助服务市场时发电企业的联合报价模型。日前电价的不确定性通过获取典型电价场景并基于Kantorovich距离的向前选择方法进行场景削减。基于条件风险价值(conditional value at risk,CVaR)将发电企业选择竞价策略时的风险偏好进行量化并建立模型,再对所提模型进行计算求解得到相应的报价策略。算例分析结果表明,所提模型可以为发电企业提供有效的报价策略,灵活应对电价波动。相较于不参加二次调频辅助服务市场时发电企业收益得到提升,且企业可根据自己的风险偏好更改模型中的风险因子,以得到理想报价策略。展开更多
