Patents Assigned to STATE GRID INFORMATION & TELECOMMUNICATION BRANCH
  • Patent number: 9722430
    Abstract: A method for analyzing a user load in conjunction with time information and a system thereof are provided. In the case that an enterprise operates in a non-full-time operational mode, operation periods of the enterprise are adjusted, electricity prices for respective adjusted operation periods are obtained, and the electricity prices are multiplied with electricity consumptions to obtain electricity charges of the enterprise. In the case that the enterprise operates in a full-time operational mode, electricity consumptions in respective hours of the enterprise are adjusted, the electricity consumptions are multiplied with electricity prices for the respective hours to obtain electricity charges of the respective hours of the enterprise, and the electricity charges of the respective hours are accumulated to obtain a total electricity charge of the enterprise.
