Electric Vehicle Charging Management Using Auction Mechanism for Reducing PV Curtailment in Distribution Systems

Abstract

This paper proposes an electric vehicle (EV) charging management scheme for effective utilization of photovoltaic (PV) power based on an auction mechanism. The proposed scheme coordinates an amount of self-consumption of PV output by shifting the charging period of customers' EVs, and it reduces PV curtailment caused by voltage rise in low-voltage distribution systems (LVDSs). The auction mechanism is introduced in order to assure both the equity of benefit in each customer and the autonomy that enables customers to voluntarily participate in the EV charging management scheme. The authors perform numerical simulations based on a Japanese distribution system model and evaluate the effectiveness of the proposed scheme. The results show that our proposed scheme reduces the residential operation cost and the PV curtailment in LVDSs without an enhanced communication network even taking into consideration the effects of forecasting errors of electricity demand and PV output, and unexpected disconnection condition of several EVs.

Designing Sustainable Smart Cities: Cooperative Energy Management Systems and Applications

“…These various types of EMSs become essential components of the whole smart city [173]. Specifically, from the viewpoint of future popularization and controllability, EVs are expected to be used for power system operation including the Vehicle to Grid (V2G) scheme [174][175][176][177][178][179][180][181][182].…”

Model Predictive Control Approach for Optimal Power Dispatch and Duck Curve Handling Under High Photovoltaic Power Penetration

“…The cost of the load shedding at every bus for each hour is fixed to 500 $/kWh [32]. The PV curtailment cost is calculated as in [3]. The PV curtailment cost is 286 $/kWh.…”

“…High penetration of RESs also leads to a new operating paradigm where the grid has too much RES without corresponding adequate demand. This leads to curtailment of the RES output which might be counterproductive [3]. The duck curve requires the use of more flexible and expensive power sources in order to smooth the sharp increase and decrease in the peaks.…”

Joint Demand Response and Energy Trading for Electric Vehicles in Off-Grid System

“…In an off-grid system (also called a microgrid without support from the maingrid), there are various forms of demand and supply problems in the literature that aim to optimize the operation of diesel generators or energy storage as backup energy supplements [7]. More recently, due to the high costs associated with the operation of such a backup system, a deregulated market-based approach that considers the demand of EVs known as energy trading in EVs is considered as a promising cost-effect maneuver [8]- [10]. In [8]- [10], the authors proposed an auction method to manage energy supplement in a region.…”

However, the auction is a method of inducing power transaction through voluntary price competition of market participants.…”
