摘要家庭能量管理系统作为智能电网在用户消费侧的重要组成部分,是智能家庭优化运行的核心。针对装有光伏设备的家庭用户,提出一种事件驱动的在线能量管理算法,基于李雅普诺夫优化方法对家庭中的可控负荷进行调控,采用非预测机制,只需获取当下时刻的相关变量即可实时做出调控决策,可以在分布式电源发电、用户负荷及市场电价的波动场景下快速调控能量。采用事件触发机制决定是否进行在线优化决策,减少触发频率和不必要的计算量。通过仿真结果对比分析可知,该算法能有效降低用户用电成本,占用计算资源少,有利于实现家庭用户的低成本能量管理。

Abstract：As an important component of smart grid on the user side, the home energy management system is the core of the optimal operation for smart home.In this paper, the energy scheduling problem for a household equipped with photovoltaic devices is investigated.An online energy management algorithm based on event triggering is proposed.The Lyapunov optimization method is adopted to schedule the controllable load in the household.Without the forecasting of the related variables, the real-time decisions can be made only based on the current values of the variables.The algorithm could regulate energy fast under the fluctuations of the distributed generation, the electricity demand, and the market price.The event-triggering mechanism is adopted to trigger the execution of the online algorithm, so as to cut down the execution frequency and unnecessary calculation.A comprehensive comparison of the results obtained from simulation shows that the proposed algorithm could effectively decrease the electricity bill of users.Moreover, the required computational resource is small, which contributes to the low-cost energy management of smart home.
