Problems solved by technology
The main methods used are analytic hierarchy process, expert scoring method, etc., but some methods involve many automatic index systems, the objectivity of the methods used is lacking, and the evaluation results may be distorted or not robust; some methods use expert opinions , try to avoid more subjective evaluation criteria, but it will still be affected by the knowledge, experience, and preferences of experts, and has greater contingency; in general, the existing methods are insufficient for the use of historical data of automation construction investment, especially for reliability. It is due to the lack of attention paid to the time of user failure and power outage, and it is difficult to obtain a specific evaluation model that is targeted and scalable

The invention provides a method for evaluating investment benefits of distribution network automation construction. The method first selects distribution network automation construction investment indicators and core indicators of reliability, and then performs automation investment indicators and reliability based on historical automation construction investment and power outage data. 0‑1 standardization or range standardization of indicators, and then construct differential incremental indicators and ratio incremental indicators, based on Pearson correlation coefficient and Kendall rank correlation coefficient for paired screening of reliability indicators and automated investment indicator combinations, Determine the final reliability index and automation investment index pool, construct the association model of automation investment index and power outage reliability index through improved linear regression, and then use the goodness of fit coefficient and significance weight coefficient of improved linear regression to finally obtain a significant impact The version combination of automated investment indicators for reliability indicators, and the weight coefficient of the improvement degree of reliability indicators for automated investment projects.
Description
technical field [0001] The invention relates to the field of distribution network automation investment evaluation in electric power systems, and more specifically, relates to a distribution network automation construction investment benefit evaluation method. Background technique [0002] The investment and construction of distribution network automation is one of the core contents of building a smart grid, and it is also an important measure to improve the reliability of power supply and ensure the electricity demand of industries and residents. With the continuous increase of investment in automation projects, objective and reasonable evaluation of the benefits generated by automation investment projects is an important part of the work to promote the development of grid automation construction in a scientific, environmentally friendly and sustainable direction. Through the reliability-based benefit evaluation of distribution network automation investment, it is possible ...
