    • Certain embodiments of the invention may include systems, methods, and apparatus for estimating power time of use. According to an example embodiment of the invention, a method is provided for synchronizing local system time with a network clock for estimating power time of use. The method includes storing power usage data and initial time stamps, wherein the initial time stamps are derived from one or more of a local clock or broadcast network time; receiving data comprising network time; adjusting the local system time with a PID loop, wherein the PID loop adjusts the local system time based at least in part on a difference between the local clock and the received network time; storing, with the power usage data and initial time stamps, an indicator when the difference is greater than a predetermined value; and determining synchronization when the difference is less than or equal to a predetermined value.
    • 本发明的某些实施例可以包括用于估计使用功率时间的系统,方法和装置。 根据本发明的示例实施例,提供了一种用于使本地系统时间与用于估计使用功率时间的网络时钟同步的方法。 该方法包括存储功率使用数据和初始时间戳,其中初始时间戳从本地时钟或广播网络时间中的一个或多个导出; 接收包含网络时间的数据; 利用PID循环来调整本地系统时间,其中PID循环至少部分地基于本地时钟和接收到的网络时间之间的差异来调整本地系统时间; 当所述差异大于预定值时,与所述电力使用数据和初始时间戳一起存储指示符; 以及当所述差小于或等于预定值时确定同步。
