Problems solved by technology
[0004] However, for the benefits of the power grid, the research scope of the existing technology is narrow, focusing on the benefits of the power grid itself; and there is no relatively mature method for evaluating the environmental benefits of the transmission grid after the large-scale integration of new energy sources; furthermore, due to the lack of The comprehensive evaluation system for safety does not include the impact of safety in the current power facility asset utilization evaluation of relevant state ministries and commissions, so that the particularity of power grid asset efficiency evaluation is not fully understood
Therefore, in terms of comprehensive evaluation of transmission network security risks, the existing technology has been unable to meet the practical requirements

The invention provides a method for establishing a transmission grid safety risk comprehensive evaluation index system. The method comprises the steps of establishing an index system hierarchical structure which sequentially comprises a target layer, a criterion layer and an index layer; dividing indexes in the target layer into a transmission grid safety risk index and a transmission grid social benefits index; establishing evaluation indexes for the transmission grid safety risk index, which comprise a transmission and distribution equipment risk event index, a transmission grid structural risk index, a transmission power supply risk index and an extreme event risk index; establishing a clean utilization energy index and a continuous power supply social benefits index; establishing evaluation indexes respectively for the transmission and distribution equipment risk index, the transmission grid structural risk index, the transmission power supply risk index and the extreme event risk index, and calculating the transmission grid safety risk index; establishing evaluation indexes respectively for the clean utilization energy index and the continuous power supply social benefits index, and calculating the transmission grid social benefits index; and calculating a transmission grid safety risk comprehensive evaluation index.
Description
technical field [0001] The invention belongs to the field of electric power generation, transformation or distribution, and in particular relates to a method for establishing an index system for comprehensive evaluation of transmission network safety risks. Background technique [0002] In the future, society's demand for electricity will increase day by day, and the energy crisis and environmental situation will become more and more severe. In order to rationally and optimally allocate resources and solve some problems existing in my country's energy and electric power development, it is imperative for power grid companies to change the grid development mode and establish the development goal of building a world-class power grid. [0003] The future transmission grid system is highly complex, including various links, and each subsystem is coupled with each other. In order to better plan and build a transmission grid characterized by a strong smart grid, it is necessary to c...
