Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of power dispatching in the prior art, which is usually dispatched in a unified manner by the dispatching control center. The unified dispatching has a certain delay in information, and the power actually distributed to each region may not match the actual local demand. , at the same time, the power dispatched in various regions cannot be transmitted in a fast sum, which will easily cause the control center to simultaneously process a large number of power dispatching tasks in different regions in a short period of time, and the dispatched power uploaded here is a theoretical figure, while There will be different degrees of power loss during the transmission process, so there will be a certain difference between the power that needs to be dispatched and the power that is actually dispatched to the target area, and a method for forecasting and dispatching of the power system is proposed

Abstract

The invention discloses a prediction and scheduling method for an electric power system, and particularly relates to the field of electric power management. The system comprises a data exchange center, an internal communication system, an electric power production system and an electric power transmission system, wherein the data exchange center comprises a communication scheduling subsystem, a cooperative command subsystem, an analog quantity measuring and calculating system, an instruction transmission subsystem and a GPS positioning system, and a data interaction end of the communication scheduling subsystem is in signal connection with a data interaction end of the cooperative command subsystem. According to the system, the analog quantity measuring and calculating system is designed to measure and calculate the dispatched electric power to measure and calculate the actual dispatched effective electric power and the theoretical dispatched electric power, and the data results measured and calculated for many times are recorded and calculated to serve as a standard template for subsequent dispatching, and the template can be updated in real time, an error between each measurement result and an actual result is reduced, so a user can more intuitively measure a value needing to be reported when applying for power dispatching.

Description

technical field [0001] The invention relates to the field of electric power management, in particular to a method for predicting and dispatching an electric power system. Background technique [0002] The power system is an electric energy production and consumption system composed of power plants, power transmission and transformation lines, power supply and distribution stations, and electricity consumption. Power transformation and distribution supply electric energy to various users. In order to realize this function, the electric power system also has corresponding information and control systems in various links and different levels to measure, adjust, control, protect, and communicate the production process of electric energy. and scheduling to ensure that users obtain safe and high-quality electric energy. [0003] In the prior art, power dispatching is usually carried out by the dispatching control center in a unified manner. Unified dispatching has a certain delay...
