Research On Information Protection Of Power Supervisory System In Regional Energy Internet

Energy Internet can not only satisfy the sharing under the reliability of satisfying people’s power supply demand,but also realize the efficient development and utilization of clean energy.At the same time,it has also comprehensively adjusted the strategic deployment of energy development and traditional energy consumption methods.Regional Energy Internet is a Pilot Implementation Scheme of Energy Internet.It has many advantages in two-way interaction,full autonomy,flexible access,complementary utilization of multiple energy sources and running time.Electric power monitoring system can collect state variables and other power parameters in real time.It can also monitor the operation status of the system in real time,detect faults in time,and make timely decision and disposal.However,due to the complex access environment,flexible access mode and large number of access terminals,the regional energy Internet power monitoring system is facing more security challenges.Based on the above problems,this paper carries out research on information protection of power monitoring system of regional energy internet.Firstly,by analyzing the model and characteristics of regional energy Internet and power monitoring system,we define the model structure of power monitoring system based on regional energy internet.Then we analyze the risk points of this model and discuss the feasibility of information protection research based on this model.Secondly,combined with the five basic attributes that affect information security,we summarize the risk points that power monitoring system is vulnerable to.In addition we classify the related attacks and describe the attack scenarios.Thirdly,through asset identification and vulnerability analysis of power monitoring system,we propose a vulnerability quantification model based on AHP and TOPSIS algorithm.What’s more,we also constructed a vulnerability example of power monitoring system and analyzed the results of the quantitative model.Beyond that,we construct a semi-physical simulation model of power plant based on regional energy Internet source end.And we carry out real-time detection of the operation status of the power monitoring system.At the same time,we use offensive and defensive means to test and verify the platform of information security testing and verification,and verify the feasibility of information protection of power monitoring system based on regional energy internet.Finally,we discuss the future information security protection measures.
