Grid Security Risk Management Approach
Chapter I. General provisions
Article 1 In order to effectively prevent the risk of large-scale power grid outages, the establishment of scientific prevention-oriented, process management as a means of whole-process closed-loop supervision as a means of support for the full coverage, full control, efficient and coordinated grid security risk management mechanism, the development of this approach.
The second power grid enterprises and their power dispatching agencies, power generation enterprises, power users and other grid owners of the main unit in the grid security risk management and control of the main responsibility, the National Energy Board and its dispatching agencies, the local power management departments are responsible for their respective areas of responsibility within the supervision and management of the grid security risk management work.
Article 3 The relevant units should attach great importance to grid security risk management and control work, regular combing of grid security risks, targeted risk identification, risk grading, risk monitoring, risk control, risk management work, in order to timely understand, grasp and resolve grid security risks.
Chapter II. Grid Security Risk Identification and Ranking
Article 4 The power grid enterprises and their power dispatch institutions are responsible for organizing the risk identification, power generation enterprises, power users and other grid-connected subject owners should cooperate with the risk identification work. Risk identification should be clear that the risk may lead to the consequences, find the cause of the risk, to determine the failure scenarios.
Article 5 The consequences that may result from the risk mainly include the proportion of grid load reduction or power outage users, as well as indicators such as the degree of impact on the stable operation of the grid and the reliable supply of electricity caused by the failure and shutdown of units, disorderly disconnection of other grid-connected subjects, and power outage of important power users.
Article 6 The causes of risk formation mainly include grid structure, power supply layout, load characteristics, equipment status, personnel behavior, operating environment and other factors. Part of the risk can be formed by a combination of multiple causes.

chapter vii. bylaws
Article 34: All references to "above" in this scheme include the present number.
Article 35 These Measures shall come into force on the date of publication, and the former Measures for Grid Security Risk Control (Trial) (Guoneng Security [2014] No. 123) shall be repealed at the same time.
Policy Interpretation of the Grid Security Risk Management Approach
In order to further improve and perfect the grid security risk control mechanism, effectively prevent the risk of large-scale grid outages, and safeguard the safe development of the new electric power system, the National Energy Administration organized the revision of the "Grid Security Risk Control Measures (for Trial Implementation)" (hereinafter referred to as the "Measures").
In 2014, the National Energy Administration issued the Measures for Grid Security Risk Management and Control (Trial) (National Energy Security [2014] No. 123), which plays an important role in reducing and controlling all kinds of risk factors for grid security, and preventing large-scale blackout events, and is widely praised by electric power regulators and electric power enterprises. In recent years, laws and regulations, policy documents, national standards such as the Guidelines for Security and Stability of Electric Power Systems and other laws and regulations, policy documents and national standards have been formulated (revised), promulgated and implemented, and the country has new requirements for the work of grid security risk management and control. At the same time, the rapid expansion of the grid scale over the past ten years, the more complex system operating characteristics, grid security risks have increased significantly, the need to further improve the level of grid security control through the revision of the Measures.
Grid Security Risk Management Measures" is divided into seven chapters and 35 articles, generally following the original framework structure, solidified and retained the mature experience and practice, on this basis, to further strengthen the source governance, targeted to supplement the new power system to adapt to the new challenges of the new issues of the control measures, focusing on the revision and improvement of the content of the five aspects.
First, the overall structure of the manuscript has been optimized. Chapter 2, "Grid Security Risk Identification" and Chapter 3, "Grid Security Risk Grading" have been combined into one chapter, which has been changed to "Grid Security Risk Identification and Grading". Chapter 6, "Interface between risk management and control and other work", was changed to "Grid security risk management", which more clearly reflects the requirements of the whole process of grid security risk management and control in the structure.
Secondly, it supplements the scope of grid security risk management and control and the main body of responsibility. The new grid-connected main body into the scope of grid security risk management and control, clear grid enterprises, power generation enterprises, power users and other grid-connected main body of the owner unit and other risk-related party responsibilities.
Third, the principles of grading grid security risks have been refined. Compared with the "Regulations on Emergency Disposal and Investigation of Electric Power Security Accidents" (State Council Decree No. 599) in the four levels of electric power security accidents, the original three-level risk was revised to a four-level risk. At the same time, considering the importance of power supply, the county power grid will be included in the fourth level of risk management and control.
Fourthly, it highlights the source management of grid security risks. From the planning, design, construction, hidden danger investigation and management, reliability management, material management, disaster prevention, emergency management and other aspects, comprehensively detailed and clear governance requirements of each link.
Fifthly, it has strengthened the connection with the actual work of grid security control. The annual operation mode analysis mechanism has been incorporated into the work of grid security risk control. New key periods of grid security risk control work, requiring power grid enterprises and their power dispatching agencies to organize and carry out peak summer and peak winter special security risk analysis, and form special risk control reports. The long-established annual operation mode reporting and analysis meeting system has been incorporated into the grid security risk control system to promote scientific analysis to guide risk management and control, quantitative research and judgment to promote plant and network synergies, and to supervise the implementation of major risk management and control measures.
