Abstract

The invention provides an electricity demand prediction method and a new energy system, and the method comprises the steps: determining a new energy generation power prediction curve and a load power prediction curve of each to-be-predicted sub-cycle in a to-be-predicted cycle; superposing the new energy power generation power prediction curve and the load power prediction curve of each to-be-predicted sub-period to obtain a demand power prediction curve of each to-be-predicted sub-period; determining the maximum demand of each to-be-predicted sub-cycle according to the energy storage discharge parameters and each demand power prediction curve; selecting the maximum value of the maximum demand of each to-be-predicted sub-cycle from the to-be-predicted cycle as the declaration demand of the to-be-predicted cycle; namely, the declared demand of the to-be-predicted period is determined by predicting the new energy power generation power and the power utilization load power of each to-be-predicted sub-period and considering the influence of the energy storage discharge parameters, so that the estimation accuracy of the declared demand is improved, the basic electric charge is saved to the greatest extent, and the economical efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of electricity forecasting, and more specifically, relates to a method for forecasting electricity demand and a new energy system. Background technique [0002] There are two types of electricity bills for enterprises: one is a single system and the other is a two-part system. Among them, the two-part system not only calculates the electricity fee for electricity, but also calculates the basic electricity fee according to the distribution variable capacity or the maximum demand. The basic electricity fee is equal to the billing capacity multiplied by the basic electricity price. , Selecting a reasonable billing method to maximize the savings of basic electricity bills has become an urgent problem for enterprises to solve. [0003] At present, the declared demand can be estimated according to the past electricity consumption information and experience, or the declared demand can be estimated according to the...
