Description
Technical Field
The invention provides an intelligent node overlay network-based power system and information system combined scheduling system, and belongs to the field of information interaction and network architecture.
Background
With the continuous development of renewable energy sources, the proportion of novel renewable energy sources such as wind power and photovoltaic in a power system is continuously increased. By the end of 2018, the renewable energy power generation and installation machine in China reaches 7.28 hundred million kilowatts, and the renewable energy power generation and installation machine is increased by 12 percent on year-on-year basis; wherein, wind power installation 1.84 hundred million kilowatts, photovoltaic power installation 1.74 hundred million kilowatts, increase 12.4% and 34% respectively on a same scale. It is anticipated that large scale access to renewable energy sources will be an important feature of future power systems. But renewable energy sources also tend to have strong uncertainty, which makes the power supply reliability of the power system lack guarantee. To overcome this uncertainty, the power system often needs to reserve enough spare capacity when scheduling the generator set output scheduling control strategy, so as to provide sufficient flexible resources for the power system.
In order to meet the demand for the use of cloud computing services, which has been rapidly increasing worldwide, cloud computing service providers build data centers according to the demand for service use, which also form a network that can communicate with each other and transfer computing tasks. The computing task is becoming an important load of the power system as an information system load consuming electric energy. Different from the traditional power load, the calculation tasks can be transferred among different data centers, and meanwhile, with the development of a high-reliability low-delay transmission technology, the calculation tasks of the data centers can also be scheduled by the power system in the future, so that flexibility is provided for the scheduling of the power system.
However, the joint scheduling of the power system and the information system has the following problems in the information interaction and network architecture:
(1) there are differences in communication protocols and data structures between power systems and information systems. Communication protocols commonly used in the power system are global protocols, such as an IEC 61850 protocol for a substation, an IEC 61334 protocol for distribution automation, and the like, while the current protocols applied to information system data center communication are often based on a local area network, so that the communication protocols of the two protocols conflict. In terms of data structure, data used in the power system is mostly state variables of the power system and belongs to an array structure, while data used in the information system is mostly calculation tasks and belongs to a queue or stack structure, so that the joint processing and analysis of the data have conflicts.
(2) Joint scheduling imposes a computational burden on both the power system and the information system. In order to analyze and process the system state in real time and realize the joint scheduling of the power system and the information system, a complex information processing device and a policy control device are often required to be additionally installed. If the above devices are added to the power system and the information system, the power system also has functions of detecting the frequency stability of the system in real time, monitoring the out-of-limit situation of the power flow of the system line, and the like, and the information system also needs to detect the loss rate of information transmission, and the like, so that the joint scheduling additionally increases the calculation burden of the power system and the information system, and influences the realization of the original functions.
At present, no network architecture can realize joint scheduling of a power system and an information system.
