Joint dispatching system of power system and information system based on intelligent node overlapping network

Abstract

The invention proposes a joint dispatching system of a power system and an information system based on an intelligent node overlapping network, which belongs to the field of information interaction and network architecture. The system includes multiple interconnected intelligent nodes; each intelligent node includes: intelligent node interaction port, power system interaction port, information system interaction port, data fusion convergence module, data storage module and data processing module; each intelligent node obtains Power system and information system information and the local optimal joint dispatch control strategy on other intelligent nodes, after processing the aggregated power system and information system information, generate the local optimal joint dispatch control of the electric power system and information system of the intelligent node The strategy is sent to the computing load dispatching unit of the information system and the energy dispatching unit of the power system for implementation. The invention realizes the deep fusion perception and control of the power system and the information system, and improves the reliability and safe and economical operation capability of the power system.

Description

technical field [0001] The invention proposes a combined dispatching system of a power system and an information system based on an intelligent node overlapping network, which belongs to the field of information interaction and network architecture. Background technique [0002] With the continuous development of renewable energy, the proportion of new renewable energy such as wind power and photovoltaics in the power system continues to increase. As of the end of 2018, my country's installed capacity of renewable energy power generation reached 728 million kilowatts, an increase of 12% year-on-year; among them, the installed capacity of wind power was 184 million kilowatts, and the installed capacity of photovoltaic power generation was 174 million kilowatts, an increase of 12.4% and 34% year-on-year respectively. It is foreseeable that large-scale access to renewable energy will be an important feature of the future power system. However, renewable energy also often has s...

Problems solved by technology

In terms of data structure, most of the data used in the power system are state variables of the power system, which belong to the array structure, while most of the data used in the information system are computing tasks, which belong to the queue or stack structure, which makes joint processing and analysis of data exist. conflict

[0006] (2) Joint scheduling increases the computational burden of the power system and information system

If the above-mentioned devices are installed in the power system and information system, since the power system is also responsible for real-time detection of system frequency stability, monitoring system line power flow limit and other functions, and the information system also needs to detect the loss rate of information transmission, etc., so Joint dispatch will increase the computational burden of the power system and information system, affecting the realization of their original functions

[0007] At present, there is no network architecture that can realize the joint dispatch of power system and information system
