Estimation of the potential of energy efficiency increase in SMARTGRID systems with prosum-ers based on electric vehicles
The modes of operation of power transformer substations 6 (20)/0.4 kV are analyzed. Scientific and technical solutions for the use of electric vehicles as prosumers of electric energy are substantiated. The potential influence of electric cars on electricity losses in "smart" electric networks is determined. Feasibility study of expediency of using electric mobiles as prosumers from the standpoint of loss reduction and efficiency of network equipment use is given. Quantitative indicators of the potential of equalization of the daily schedule of electric loads of the typical area of consumers of city electric networks are determined. The main indicator is the reduction of electricity losses in transformers by 7-10% compared with the existing ones when regulating the mode from the side of 0.4 kV with help of electric vehicles. Additionally, the possibility of increasing the capacity of electrical networks up to 45% identified.
