Method and device considering joint scheduling of power system and information system

Abstract

The invention provides a method and device considering the joint scheduling of a power system and an information system and belongs to the field of information energy systems and the field of resourcejoint optimization scheduling methods and devices. The device comprises a joint scheduling intelligent control module, a joint scheduling intelligent decision module, a power system parameter readingmodule and an information system parameter reading module. The method comprises a step of establishing the joint scheduling model considering the power system and the information system, wherein thejoint scheduling model is formed by an objective function and a constraint condition, and a step of solving the model to respectively obtain an optimal value of the generation power of each node generator in the power system in each time period and an optimal value of each time period information transmission quantity in each information transmission channel in the information system, i.e., an optimal scheme considering the joint scheduling of the power system and the information system is obtained. According to the method and the device, the joint scheduling operation of the power system andthe information system can be realized, through the cooperative operation of the power system and the information system, the load flexibility of the information system is brought into full play, meanwhile, the efficiency and reliability of the power system are effectively improved, and joint scheduling operation of the power system and the information system is supported.

Description

technical field [0001] The invention relates to a method and device considering joint dispatching of electric power system and information system, and belongs to the field of information energy system and resource joint optimal dispatching field. Background technique [0002] In the power system, the proportion of low-carbon and clean new renewable energy sources (such as wind power, photovoltaics, etc.) is increasing. As of the end of 2017, my country's installed capacity of renewable energy power generation reached 650 million kilowatts, an increase of 14% year-on-year; among them, the installed capacity of wind power was 164 million kilowatts, and the installed capacity of photovoltaic power generation was 130 million kilowatts, an increase of 10.5% and 68.7% year-on-year respectively. A high proportion of renewable energy access will surely become an important feature of the modern power system. Due to the strong uncertainty of renewable energy, the power supply reliabi...

Problems solved by technology

However, because the existing information system scheduling method only considers the system itself, it cannot give full play to the flexibility of information system load transfer in space.

[0006] 2) The efficiency and reliability of the power system cannot be further improved

However, the existing power system scheduling method only considers the system and ignores the scheduling of the information system load, so it cannot improve the efficiency and reliability of the power system in combination with the information system load

[0007] At present, there is no method and device to realize the joint dispatching of power system and information system
