Loss calculation and optimisation in low-voltage networks

Technical energy losses in low voltage networks are usually estimated by balancing feeded and delivered energy of the analysed grid area, but generally it is not possible to derive information for loss reduction opportunities out of these data. The proposed method calculates grid losses in low voltage networks and takes the effect of short time load peaks as well as unbalanced loads into consideration by using standard load profiles in connection with an obtained loss correction function. It provides the option to point out high loss areas or equipment owning a high potential for loss reduction, to allow optimised investments in development and maintenance of the system.
