N2 - An economically efficient day-ahead tariff (DT) is proposed with the purpose of preventing thedistribution grid congestion resulting from electric vehicle (EV) charging scheduled on a dayaheadbasis. The DT concept developed herein is derived from the locational marginal price(LMP), in particular the congestion cost component of the LMP. A step-wise congestionmanagement structure has been developed whereby the distribution system operator (DSO)predicts congestion for the coming day and publishes DTs prior to the clearing of the day-aheadmarket. EV fleet operators (FOs) optimize their EV charging schedules with respect to thepredicted day-ahead prices and the published DTs, thereby avoiding congestion while stillminimizing the charging cost. A Danish 400V distribution network is used to carry out casestudies to illustrate the effectiveness of the developed concept for the prevention of distributiongrid congestion from EV charging. The case study results show that the concept is successful ina number of situations, most notably a system over-load of 155% can be successfully alleviatedon the test distribution network.
