Problems solved by technology

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

Embodiment Construction

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0054] A method for comprehensive evaluation of power grid investment strategy benefits based on FCM algorithm, the details are as follows:

[0055] 1. Calculate the fuzzy value according to the membership function

[0056] According to the theory of aggregation of historical points, the historical data of the key factors affecting investment ability are collected and analyzed. The vertical axis is a dimensionless value, and each key indicator is an abscissa, ...

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...
