在能源互联网的构想中，电力用户将与电力公司展开充分互动，作为需求侧管理(demand-side management，DSM)中最重要的策略之一，负荷转移的执行模式也将随之发生变化。DSM的执行涉及到用户的参与程度，但现阶段DSM和博弈论的综合研究中仅考虑用户参与与否。为此，将用户实际参与概率(频率)加以考虑，构建了一个调峰指标分摊下用户之间的非合作博弈模型，其中每个用户通过决定何时参与DSM 来最小化满足日常用电需求的期望效用(用电成本)，并基于虚拟博弈算法提出了一种求解近似混合策略纳什平衡点即参与概率的算法。最后，应用实际数据仿真计算出了用户参加的概率，并验证了所提算法的收敛性。

As an important feature of demand-side management (DSM), load shifting is undergoing changes due to customer participation in open energy internet. However, most existing DSM studies using game theory focus on absolute participating/non-participating strategy. In contrast, this paper takes participation frequency into account so as to explain possibility of load shifting in practice. In particular, a non-cooperative game is formulated between customers, where each customer can decide whether to participate in DSM and will minimize expected utility (cost function) reflecting their daily electricity consumption. Then, a novel algorithm based on fictitious game is proposed to obtain mixed Nash equilibrium and participation frequency. Simulation results assess participation probability of practical customers and verify convergence of the proposed algorithm.
