“…Then the target is to increase the total delivered charging energy, compared to the rule-based method. To get information about available flexibility, we assume that the PEV drivers submit their preferences regarding departure time and charging demand (Xu et al, 2014;, for instance through an app. For simplicity reasons we assume that the PEV drivers reveal their true preferences.…”

“…They divide into ancillary services, system balancing and network congestion management, spot markets and generation capacity markets. A clearinghouse concept for distribution-level flexibility services, FLECH, is proposed by C. Zhang et al (2014). The DSO requests a service type for handling overload or voltage problems, aggregators bid their prices and quantities, and the FLECH market runs single-side auctions or super market trading.…”

“…An LP model was formulated in [11] to maximize the profit of aggregator and minimize the charging cost of EVs. In [12], a hierarchical control scheme was developed to minimize the charging cost and peak load caused by EV charging across multiple aggregators. The overall charging profile of each aggregator is first allocated at the power distribution level and a heuristic method is then used to obtain the charging rate of each EV.…”

Optimal Charging and Discharging Scheduling for Electric Vehicles in a Parking Station with Photovoltaic System and Energy Storage System

Abstract:The economic and environmental benefits brought by electric vehicles (EVs) cannot be fully delivered unless these vehicles are fully or partially charged by renewable energy sources (RES) such as photovoltaic system (PVS). Nevertheless, the EV charging management problem of a parking station integrated with RES is challenging due to the uncertain nature of local RES generation. This paper aims to address these difficulties by deploying an energy storage system (ESS) in parking stations and exploiting the charging and discharging scheduling of EVs to achieve better utilization of intermittent PVS for EV charging. A real-time charging optimization scheme is also formulated, using mixed-integer linear programming (MILP) to coordinate the charging or discharging power of EVs along with the power dispatches of power grid and ESS based on the vehicles' charging or discharging priorities and electricity price preferences. Extensive simulations show that the proposed approach not only maximizes the satisfaction of EV owners in terms of fulfilling all charging and discharging requests, but also minimizes the overall operational cost of the parking station by prioritizing the utilization of energy from PVS, ESS, and scheduling of every EV's charging and discharging.

“…Once EVSE sites and layout have been determined, other research has examined how to control PEV refueling to improve grid performance [22,23], minimize electricity cost [24], or both [25,26]. If special EVSE with bi-directional capabilities are installed, a PEV battery can be discharged for the purposes of supplying electricity in support of improving the performance of a building [27][28][29], micro-grid [30][31][32], or macro grid [33] as well as reducing the need for electric energy storage in systems with high renewable penetrations [34].…”
