Smart charging of EVS under different grid tariff structures

Artikel i vetenskaplig tidskrift, 2022

An effective way to incentivise customers to become more flexible in their electricity consumption is to utilize grid tariffs that reflect the actual grid conditions. This paper compares the effectiveness of different grid tariffs in promoting demand-side flexibility as well as their impacts on the annual revenue of the distribution system operator. An optimization model was developed and used in a case study investigating the impact of 500 end-users being flexible. In addition, a future scenario with a high share of electric vehicles is analysed to evaluate the impact of different charging strategies on the annual revenue for the distribution system operator was investigated. The results show that more progressive demand charges that reflect the actual grid conditions can effectively avoid an increased peak demand in the distribution system and provide customers with incentives to become more flexible.
