市场力风险会给电能交易带来严重危害，然而目前缺乏电能交易网络风险规避研究的方法。为此利用电能交易市场中流动的交易量将所有市场参与者连接为一个网络，将交易量的流动渠道定义为交易通道，然后基于适度冗余的思想，借鉴信息论中信息熵和自互信息的概念，构建了电能交易策略抗市场力风险性能的评估模型---通道充裕度模型。利用该模型对2种交易策略下的实际交易网络对比分析，得到了充裕度较高的交易网络具有弱化网络关键节点市场占有率能力的结果，表明所采用的交易策略在抗击市场风险和维护网络健壮性方面具有优势，证明了所构建模型的合理性和实用性，可以为电能交易风险规避决策提供了参考依据。

The power transaction interest is seriously damaged by the risk originating from market power,how-ever,the researches on risk aversion of power transaction are lack.In this paper,all power market participants are integrated by transaction volumes flowing in power market,the channel which transaction volumes flow in is defined as power supply channel.Based on the theory of redundancy and information entropy,an evaluation model of power transaction strategy is presented-the evaluation model of channel adequacy.According to the analysis on real power transaction networks under two different transaction strategies,it could be concluded that the power transaction network which has high channel adequacy can weaken the market share of key node. It proves that the strategy adopted in this network has advantage in resisting transaction risk and maintaining the network robustness.It verifies the rationality and practicability of the proposed model and provides a refer-ence for making decisions contributing to avoid market power risk.
