Economic Value and User Remuneration for EV Based Distribution Grid Services

This paper describes a method to estimate the monetary remuneration for the EV user support in distribution grids. The economic expenses of the conservative reinforcement solution are used for developing the methodology which is first derived and afterwards applied to a piece of Danish distribution grid consisting of 127 customers. In the conservative scenario the DSO should invest approx. 388718 DKK (52000€) on new upgraded components. With EV support service the potential available money for the EV support remuneration is evaluated to be 187 DKK/week (25€/week). Considering a customer with an average EV load consumption, the annual remuneration would be 77 DKK (10€). It is concluded that, if the components are severely overloaded, for the DSO it is more cost effective to invest in components upgrade. Conversely if the components are barely overloaded or close to their limit, the EV user support can benefit both the DSO and the users.
