This paper presents an optimal day ahead schedule for a smart distribution network (SDN) using Electric vehicles (EVs) as one of the distributed energy resource (DER) in accordance with the variation in power market price. To avoid the adverse effect of massive EV integration on SDN, a coordinated charging/discharging strategy is worked out. Thus, the main objective is to minimize the hourly operational...
Uncoordinated charging of electric vehicles (EVs) using level 2 chargers, which have high power requirements (6–11kW), is a concern to power grid operators because it can lead to voltage instability. One solution to this issue is to coordinate charging scheduling. Various scheduling schemes have been proposed but discussion on the potential impact of the schemes to EV owners' comfort is very limited...
Demand side management is a useful and necessary tool in smart grid energy management system to reduce total power demand during peak demand periods and hence, enhancing grid sustainability and reducing overall cost. This paper discusses a new load shifting approach for demand side management in smart grid energy management. This approach optimizes the consumption curves of household, commercial and...
In the smart grid environment, Electric Vehicles (EVs) are emerging as an important means of transportation to reduce greenhouse gas emissions. However, the large adoption of these vehicles may pose a significant threat to the stability of the electrical grid due to its uncertain charging pattern. This paper proposes a charging-discharging strategy for electric vehicles in a controlled environment...
Smart energy systems integrate renewables and demand response. Most European electricity markets coordinate the resulting time-varying flexibility in demand and supply by organising day-ahead trade with Walrasian mechanisms, using simultaneous call auctions and sealed bids. These mechanisms give bidders no information on each other's values and flexibilities until after clearing. In this paper we...
