Abstract

The invention discloses an investment evaluation method based on power grid safety. The method comprises the following steps: S1, defining and grading power grid investment; s2, obtaining an evaluation dimension and a key characteristic quantity of power grid investment evaluation; s3, establishing an investment evaluation model based on power grid safety; s4, performing investment evaluation according to the key characteristic quantity and an investment index obtained by the investment evaluation model; according to the invention, the safety and reliability conditions of the power grid can bejudged through the investment indexes, power grid planning is converted into multi-target planning from single-target dialogue, the load coordination capacity of the user side is fully considered, and the reliability and inclusivity of power grid planning are improved in combination with the source-load interaction indexes; a high-elasticity power grid investment evaluation platform is established, the depth and the breadth of power grid investment indexes and data are improved, the user side load data can be deeply mined, the business environment can be optimized, and the user electric powerobtaining feeling is improved.

Description

technical field [0001] The invention relates to the technical field of distribution network investment decision-making, in particular to an investment evaluation method based on network security. Background technique [0002] The current evaluation of power grid construction investment mainly adopts the traditional post-evaluation method of engineering projects. The evaluation results have certain objectivity and reference value, but there are two major deficiencies and defects: on the one hand, it is mainly reflected in the fact that the evaluation itself is only based on the power grid investment. From the economic point of view, the cost and benefit are taken as the main indicators to evaluate the investment status of power grid construction, and have little connection with the structure of the power grid itself, the security and reliability of the power grid. In the actual power grid operation process, the investment in power grid construction is the guarantee The contin...
