Embodiment Construction

[0028] In one embodiment, a comprehensive evaluation method for smart grid demonstration projects, such as figure 1 shown, including the following steps:

[0029] Step S110: Receive the micro-evaluation index data set of the smart grid.

[0030] The micro-evaluation index data set includes a variety of data, each of which is a micro-evaluation index of the smart grid. The types of micro-evaluation indicators are not unique, including benefit-type indicators, cost-type indicators and specific-type indicators. Among them, the benefit type index refers to the increase of the index value with the increase of the index value; the cost type index refers to the increase of the index value with the decrease of the index value; and the specific type index refers to the value in the middle of a certain value or sub-range its highest score.

[0031] Step S120: Calculate the weight of each data in the micro evaluation index data set by using the combined weighting method based on the m...

Abstract

The invention relates to a method and system for comprehensively evaluating a smart power grid demonstration project. The method comprises the following steps of: receiving a microscopic evaluation index data set of a smart power grid, and calculating weights of various data in the microscopic evaluation index data set by utilizing a combination weighting method based on a torque estimation theory; obtaining a macroscopic demand index value by calculation according to the microscopic evaluation index data set and the weights of the corresponding data; and, calculating weights of various macroscopic demand indexes by utilizing a DEMATEL-ANP anti-entropy weight method, and obtaining and outputting a comprehensive evaluation result according to the macroscopic demand index value and the weight corresponding to the macroscopic demand index. The weights of the data in the microscopic evaluation index data set are calculated by utilizing the combination weighting method based on the torque estimation theory; the problem that a weighting result is bias due to the fact that determination of the weight through the single weighting method can be easily influenced by the weighting method can be avoided; the macroscopic index weight is determined through the DEMATEL-ANP anti-entropy weight method; the microscopic index weight is determined through the combination weighting method based on the torque estimation theory; therefore, the comprehensive benefit can be evaluated scientifically; the evaluation reliability is high; and a guiding role can be played.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a comprehensive evaluation method and system for a smart grid demonstration project. Background technique [0002] In recent years, energy security and environmental issues have been paid more and more attention, and renewable energy has been vigorously developed. Under the voice of power grid informatization, automation and interaction, smart grid has once again received high attention from the industry, and has become a hot field that countries around the world are competing for development. However, the development of smart grid is a complex systematic project, which is still in its infancy worldwide. Its construction involves many links such as power generation, transmission, transformation, distribution, consumption and dispatching, and has great impact on my country's economy, The development of society and environment has a far-reaching impact. It is urgent to build a ...
