A smart grid simulation operation system

Abstract

A smart grid simulation operation system, including a grid power flow calculation center and a SCADA subsystem. The grid power flow calculation center contains a grid model and an operation program to simulate real grid operation, and the SCADA subsystem simulates smart meters and executive devices in a real grid. The present invention Integrating smart grid and network security technology, it has the same architecture, components and network interaction interface as the real grid. It can calculate the status of the grid in real time and make correct responses when the grid data changes. The same response from the power grid, and displayed to it by the Web display subsystem, in order to meet the attacker's expectations, trick it into the next attack, expose the real attack purpose and complete attack method, and finally use the audit and capture subsystem monitoring system to capture the attacker's all acts.

Description

technical field [0001] The invention belongs to the technical field of smart grid security, in particular to a smart grid simulation operation system. Background technique [0002] The smart grid (Smart Grid) system is an important industrial control system and the focus of the national "two modernizations" strategy, but there are many security holes in the smart grid, which may be invaded by attackers at any time. [0003] The number one threat to industrial control systems is malicious code attacks from the network. Industrial control systems use a large number of general-purpose protocols, general-purpose hardware and general-purpose software, and use the TCP / IP protocol to connect to the Internet, which provides sufficient convenience for the spread of malicious codes, making the security problems of industrial control systems increasingly serious. The reason why the "Stuxnet" (Stuxnet) incident caused heavy losses to Iran's nuclear power plant is that due to the curren...

Problems solved by technology

The traditional protection method is to replace the software and hardware in the power grid system to reduce the loopholes in the system, but this protection method has obvious disadvantages, namely hysteresis and vulnerability. Only when the power grid is attacked and losses are caused, the administrator Only then can we discover the existence of network attacks, so we can only passively replace the equipment, but cannot grasp the attacker's attack path, attack method, attack tool and exploited loopholes, cannot prescribe the right medicine, and cannot completely avoid the attacker's re-invasion, thus falling into the " In the vicious cycle of being attacked—replacing equipment—being attacked”
