[0069] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0070] 1) The Monte Carlo simulation method is used to generate the scene;
[0071] Using multi-scenario technology to describe the uncertainty of future electricity consumption forecast errors. According to the probability distribution of the electricity consumption forecast error value, the Monte Carlo simulation method is used to randomly sample the value of the electricity consumption forecast error value, and several scenarios are obtained.
[0072] The probability model is the basis and boundary condition of the Monte Carlo simulation method. Before the simulation, it is necessary to determine the probability distribution of the electricity consumption forecast error based on the mechanism analysis or historical data, then conduct random sampling according to the probability model, and finally establish the estimator as needed. The specific process is ...
