Electric power user baseline load calculating method and apparatus thereof

Abstract

The invention discloses an electric power user baseline load calculating method and an apparatus thereof. The method is characterized by according to a history day load curve set and a reference load curve set, forming several characteristic load curves; determining a key factor influencing a user baseline load and establishing a decision tree associated with the characteristic load curves and the key factor; and using the decision tree to carry out prediction calculating on the user baseline load, and feeding back a calculation result to each service system. A lot of data loading time is saved, accuracy of a baseline load calculating result is effectively increased, and an accurate data basis is provided for reasonably making and implementing electric power demand side management and demand response measures. Simultaneously, the apparatus is used for executing the method; an automation degree of electric power user baseline load prediction calculating is increased; baseline load prediction calculating efficiency is improved; and a problem that each service system is easy to frequently generate faults during a data interaction process is avoided.

Description

technical field [0001] The invention relates to the technical field of power systems and automation thereof, in particular to a method and device for calculating baseline loads of power users. Background technique [0002] Load characteristic analysis is the basis of smart grid research. Budgeting user baseline load based on load characteristics is an important decision-making basis for power grid expansion planning, dispatching operation, power supply construction and load management, and is of great significance for ensuring safe, economical and high-quality operation of the power grid; Demand response is the abbreviation of electricity demand response, which means that when the price of the wholesale electricity market rises or the reliability of the system is threatened, after receiving the direct compensation notice from the power supply party for inductive load reduction or the signal of electricity price rise, the power user changes Its inherent customary power consum...

Problems solved by technology

[0005] The purpose of the present invention is to provide a method and device for calculating the baseline load of electric power users to solve the problem in the prior art that it is difficult to accurately calculate the baseline load of demand response due to the large variety of loads, the large difference in characteristics, and the strong randomness of load changes. In particular, the accuracy of baseline load forecasting that only considers a certain factor is very low, and the baseline load forecasting method and system lacks automatic methods for baseline load forecasting, resulting in low efficiency of baseline load forecasting, and frequent data exchange between business systems technical problem that went wrong
