According to the spatial distribution of small and moderate earthquakes, 6 seismic dense zones are delineated. Temporal distribution of ML2 earthquakes since 1970 in each seismic dense zone has been analyzed. Based on temporal distribution characteristics and historical earthquake activity, three types of seismicities are proposed. The relationship between seismic types and crustal medium is analyzed. The mechanism of three types is discussed. Finity of strong earthquake recurrence is pro-posed. Seismic hazard in mid-long term and diversity of earthquake disaster in Shanxi seismic belt are discussed.展开更多
为应对可再生能源的供给不确定性给新能源发电企业中长期合同履约带来的挑战,本文提出了新能源发电企业与独立储能中长期合约电量确定方法。综合新能源发电的机会约束和独立储能运行约束,以发电企业和独立储能共同效益为目标,构建新能...为应对可再生能源的供给不确定性给新能源发电企业中长期合同履约带来的挑战,本文提出了新能源发电企业与独立储能中长期合约电量确定方法。综合新能源发电的机会约束和独立储能运行约束,以发电企业和独立储能共同效益为目标,构建新能源发电企业同独立储能签订中长期合约电量确定模型;通过引入条件风险价值(conditional value at risk,CVaR)和替换变量将模型重新表述为混合整数规划(mixed integer program,MIP)模型以便于求解。采用新能源发电企业月度合约电量分解曲线进行算例分析,验证了本文所提方法的有效性。同时考量新能源发电企业风险偏好、储能荷电状态等对共同效益的影响,研究表明储能荷电状态与共同收益负相关,而提高新能源发电企业风险偏好能够提高合约共同体预期收益。储能中长期双边合约电量确定方法的提出有助于促进新能源消纳和储能成本市场化疏导。展开更多
