Though imbalance electric quantity in the electric power market is small,its price is the benchmarking objective of the forward market and the spot market which may directly affect price of the electric power wholesale market. The Nordic electric power market is the first international transnational electric power market in the real sense that is significantly refer-ential to construction of trans-provincial and trans-regional electric power markets in our country. Therefore,this paper an-alyzes rules of imbalance settlement of the Nordic electric power market including the imbalance settlement model,imbal-ance electric quantity calculation and calculation of imbalance electric charge. It also sorts out responsibilities of market players and transaction settlement institutions,and clears transmission relationship between information and data. Mean-while,it introduces bill issuing process and calculation on cash deposit limit so as to guarantee benefits of the market players participating in transactions and reduce default risks. Finally,combining with practical condition of China,it proposes sug-gestions for construction of the imbalance mechanism in aspects of institution setting,contract norm,settlement mode,and so on.%电力市场中的不平衡电量虽然很小,但其价格是远期和现货市场的对标目标,直接影响电力批发市场的价格.北欧电力市场是国际上第一个真正意义上的跨国电力市场,对我国跨省、跨区电力市场的建设具有很强的借鉴作用.基于此,分析了北欧电力市场不平衡结算的规则,包括不平衡结算模型、不平衡电量计算和不平衡电费计算,梳理了在不平衡结算过程中所涉及的市场主体和交易结算机构各自的责任,明确它们之间信息和数据的传输关系.介绍了发放票据的流程和保证金额度的计算,确保参与交易的市场主体的利益,降低其违约风险.最后,结合我国的实际国情,从机构设置、合同规范、结算方式等几方面,提出不平衡机制建设的建议.
