Abstract

Abstract:

With the rapid development of power system and the promotion of power market-oriented reform,the main body of the market takes the maximization of the enterprise’s own benefits as the goal,thus reducing the investment,and the reliability problem is increasingly prominent.In this paper,based on the reliability index decomposition method of typical engineering scenarios,according to the cost-benefit ratio of investment,the investment priority planning is carried out,and under the objective of investment minimization,the optimal investment structure of reliability improvement is realized.

Key words: power system, reliability, sensitivity, cost-benefit ratio, investment optimization
