Distribution equipment operation efficiency evaluation method involving reliability and economy

Abstract

The invention relates to a distribution equipment operation efficiency evaluation method involving reliability and economy, comprising the steps of: (1) determining upper and lower limits P2 and P1 of an economical operation interval; (2) rearranging distribution equipment time sequence load curves in order of size to obtain a load duration curve; (3) determining the supplied electric quantity S1 exceeding the upper limit P2 of the economical operation interval, the supplied electric quantity S2 in the economical operation interval, and the electric quantity S3 below the lower limit P1 of the economical operation interval; (4) determining the equipment lacked electric quantity S4 and equipment loss electric quantity S5; (5) determining the correction factor alpha of the GDP generated by each kilowatt-hour according to the GDP of the area where equipment is located, social electricity consumption per year and average retail price; and (6) determining equipment operation efficiency according to an equipment operation efficiency evaluation model. The method involves the factors of safety, reliability, economic operation, utilization rate and duration, and can more comprehensively evaluate the operation efficiency of distribution equipment in a full time domain.

AI Technical Summary

Benefits of technology

This new technology helps predict how well an electricity distributor works at different times based on its own performance or needs compared against previous models that were developed earlier. It also takes into account factors like cost-effectiveness (costs) for operating it effectively over longer periods than previously possible due to technical limitations such as poor maintenance practices or environmental concerns associated therewith.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving efficient use of distributed energy resources (DERs) within an electrical grid system while also considering their impact upon other aspects such as cost savings or environmental concerns associated with them. Current methods involve analyzing each indicator separately but they may have limits due to factors like varying demand levels during different periods of activity. Therefore there needs improvement beyond just indicating how well these indexes were used alone without taking into account any more complex variables involved from day to night when the systems operate under various conditions.
