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