Power grid investment strategy benefit comprehensive evaluation method based on FCM algorithm

Abstract

The invention discloses a power grid investment strategy benefit comprehensive evaluation method. At present, the research on the power grid investment benefit evaluation is mostly concentrated in thepower market and power generation engineering, the evaluation of the investment benefit of the power grid enterprises is still in the initial stage, and the evaluation of the investment benefit of the power grid enterprises is less effectively integrated with economy and technology, more concentrated in the distribution network and a single project and less research for the power grid enterprises, and cannot measure the investment benefit of the enterprises in an all-round way. The method comprises the steps: 1) measuring and calculating a fuzzy value according to a membership function; 2) after normalizing the fuzzy value of the membership function of the key index influencing the investment strategy, adopting the FCM algorithm to perform clustering; 3) drawing the evaluation grade distribution map; and 4) using the comprehensive weight coefficient method to comprehensively evaluate the investment strategy to be evaluated. The FCM algorithm is applied to cluster the key influence index of the power grid investment strategy so as to further meet the actual application scene.

Description

technical field [0001] The invention belongs to the field of grid investment strategy evaluation, and specifically relates to a comprehensive evaluation method for grid investment strategy benefits based on an FCM algorithm. Background technique [0002] Power investment decision-making is the basic work of power system construction. Under the existing market system, power generation companies and power supply companies have become independent market entities responsible for their own profits and losses, and power investment is accordingly divided into two major parts: power generation investment and power grid investment. Power grid investment itself has the characteristics of large scale, long payback period, and many influencing factors. [0003] At present, most of the research on the evaluation of power grid investment benefits is concentrated in the power market and power generation projects, and the evaluation of the investment benefits of power grid enterprises is i...

Power grid investment itself has the characteristics of large scale, long payback period, and many influencing factors.

[0003] At present, most of the research on the evaluation of power grid investment benefits is concentrated in the power market and power generation projects, and the evaluation of the investment benefits of power grid enterprises is in its infancy. It mostly focuses on one aspect in the fields of economy, management, and technology, and seldom focuses on economic and technical aspects. Convergence, mostly focusing on distribution network and individual projects, less research on power grid enterprises, unable to fully measure the investment benefits of enterprises
