“…Razeghi et al, studied the impacts of PHEVs on a residential transformer using stochastic and empirical analysis, where the electricity demand of a neighbourhood is modelled based on measured vehicle and household data [63]. Vicini et al, discussed how increased deployment of EVs acts as a catalyst for development of transformer and home energy management systems in order to reduce the impact of EV battery charging on distribution transformers [41]. Turker et al, proposed a rule-based charging algorithm of EVs and evaluate the consequences and impacts on the aging rate of low-voltage transformers [46].…”

Transformers are one of the more expensive pieces of equipment found in a distribution network. The transformer's role has not changed over the last decades. With simple construction and at the same time mechanically robust, they offer long term service that on average can reach half a century. Today, with the ongoing trend to supply a growing number of non-linear loads along with the notion of distributed generation (DG), a new challenge has arisen in terms of transformer sustainability, with one of the possible consequences being accelerated ageing. In this paper we carefully review the existing studies in the literature of the effect of loads and other key factors on oil-transformer ageing. The state-of-the-art is reviewed, each factor is analysed in detail, and in the end a smart transformer protection method is sought in order to monitor and protect it from upcoming challenges.

“…The Australian Bureau of Statistics car vehicle usage survey showed that a passenger vehicle travelled 23.4 miles per day [16]. Some other authors use a 60-mile range to establish the SoC [17,18]. A study done by ECOtality and the Idaho National Laboratory [19] collected information from "The EV Project" vehicles and charging units.…”

“…However, the uncertain plug-in and departure time, the battery charging characteristics as well as the optimization of the EV´s charging have been disregarded in [4]. As an extension of the topic considered in [4], the coordination of EV charging within a neighborhood via HEMS considering demand response (DR) incentives has been considered in [5]. Nevertheless, the minimization of individual home owner daily electric energy costs has not been taken into account in [5].…”

The introduction of smart end-users is a vital point towards the smart grid vision. In this respect, smart households have drawn significant attention recently. Home energy management systems (HEMS) in smart households and transformer energy management units have different objectives that can sometimes be conflicting. Thus, a novel interactive optimum operating strategy that considers all possible aspects in each smart household together with internal bi-directional power flows within the household structure from economic (minimization of household daily electricity usage costs) and technical (avoidance of transformer overloading) perspective is proposed in this study. To the best knowledge of the authors, this is the first study in the literature combining all of the possible operational possibilities in HEMS of smart households together with internal household bi-directional power flows and the technical limitations of a transformer unit serving a neighborhood of smart households under a mixed-integer linear programming (MILP) framework.
