Power heterogeneous equipment control instruction dynamic execution method and system

Abstract

The invention discloses a power heterogeneous device control instruction dynamic execution method and system, and the method comprises the steps: building a third-party heterogeneous device digital certificate authentication model, and providing a digital certificate for a third-party heterogeneous device and a user thereof; expanding the control instruction message content of the third-party heterogeneous device, adding timestamps, user digital authentication feedback information, digital signatures and random numbers, and constructing the third-party heterogeneous device communication security defense method; establishing a user credit management dynamic cycle evaluation model, and calculating a dynamic credit evaluation value of the user at the moment t according to the number of abnormal operations of the heterogeneous device and the total number of operations of the user; establishing an associated electric power model of the third-party heterogeneous device, and calculating associated electric power remotely controlled by a user at the moment t; and according to the dynamic credit evaluation value and the associated electric power, establishing a credit delay response model of the third-party control instruction, and determining a time t control instruction response device. According to the invention, the operation safety of the power system under the permeation of the third-party heterogeneous device can be improved.

Description

Technical field [0001] The present invention relates to the field of power systems, in particular, to power system information physical security techniques, in particular to a dynamic execution method and system of a power heterogeneous device control command. Background technique [0002] With large-scale third-party heterogeneous equipment, users can operate high-power power equipment, such as air conditioners, electric water heaters, etc. through third-party heterogeneous equipment. However, due to the lack of strict security access mechanisms in third-party heterogeneous equipment, their own security defense measures are mixed, bringing potential safety risks to the stability of the power system. Third-party heterogeneous equipment vendors pay too much attention to network architecture openness and their compatibility, high-performance, high real-time, high availability, and high continuity of business, and ignore the security of their remote control systems. At present, the ...

Problems solved by technology

However, due to the lack of strict security access mechanism for third-party heterogeneous equipment, their own security defense measures vary, which brings potential security risks to the stable operation of the power system.

Third-party heterogeneous equipment manufacturers pay too much attention to the openness of the network architecture and the high communication efficiency, high real-time performance, high availability and high business continuity brought about by its compatibility, while ignoring the security of its remote control system

Once the malicious attacker's instantaneous control power in the target area exceeds the target system safety threshold, it will cause the frequency of the power system to shift, and it is very likely to cause the frequency instability of the target system, seriously affecting the security of the target system

[0003] However, there is currently no effective solution for the communication security of third-party heterogeneous devices

Considering that the communication security of third-party heterogeneous equipment brings potential security risks to the stable operation of the power system, it is urgent to propose a method and system for dynamically executing control commands of power heterogeneous equipment to ensure power system security from the perspective of communication and power services. Stable operation, reducing the risk of power system operation under the penetration of large-scale third-party heterogeneous equipment
