Power system and information system combined dispatching system based on intelligent node overlay network

Abstract

The invention provides a power system and information system combined dispatching system based on an intelligent node overlay network, which belongs to the field of information interaction and networkarchitecture. The system comprises a plurality of intelligent nodes which are connected with one another; each intelligent node comprises an intelligent node interaction port, a power system interaction port, an information system interaction port, a data fusion and aggregation module, a data storage module and a data processing module; each intelligent node acquires information of the power system and the information system and local optimal combined dispatching control strategies on other intelligent nodes; and after the converged information of the power system and the information system is processed, a local optimal combined dispatching control strategy of the power system and the information system of the intelligent node is generated, and the strategy is sent to an information system calculation load dispatching unit and a power system energy dispatching unit for implementation. Deep fusion perception and control of the power system and the information system are realized, and the reliability and safe and economic operation capability of the power system are improved.

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
