摘　　要：确定性电量分解算法是一种直观、简单的分解方法,但相关实证性研究较少。文中提出平均合同电量比例、平均合同电量比例与电价相关性2项公平性评估指标,采用期望、标准差和半标准差评估年度基数合同对电厂的收益和风险的影响。选用华东区域市场实际数据,分析结果表明确定性电量分解算法公平地对待发购电双方,电厂签订年度基数合同可有效降低其风险。An analysis on the deterministic contract decomposition algorithm of East China electricity market is presented. Two indices of the average contract quantity proportion, the correlation of contract quantity proportion and price are adopted to evaluate the equity of the algorithm. Expectation, standard deviation and half standard deviation are used to evaluate the income and risk of generators. An empirical analysis is undertaken based on the historical data of East China electricity market. By use of the algorithm, the results indicate that the buyer and generators are treated equally and the generator risk is reduced effectively.
