How can EV charging and discharging be regulated in real-time?
Das et al. proposed a real-time regulation method for the coordinated charging and discharging of EVs based on a dynamic planning method that takes into account the cost of EVs and the operational needs of the grid, effectively reducing the charging cost of EV users and alleviating the pressure of the grid .
Does cyclic charging and discharging reduce the cost of battery loss?
In addition, our research found that under the proposed strategy, the cost of battery loss caused by cyclic charging and discharging is negligible compared to the discharge benefit. 1. Introduction
How EV charging behavior affect the power system?
However, the charging behavior of EV users is random and unpredictable , which will increase the control difficulty of the grid , reduce the voltage quality and the stability of the power system when large-scale EVs are connected to the grid [10, 11].
Does a smart charging system reduce peak demand?
Bassam et al. propose a smart charging system (SCS) that manages the charging process of electric truck ETs at their commercial facilities, to minimize the peak demand of the aggregate load profile at the facility, showing the effectiveness of the proposed SCS in reducing the peak demand of the facility .
What is the optimal charging power optimization weight 1?
Equation (31) indicates that when the SOC of the EV is less than 0.3, the user will select the maximum charging power optimization weight λ2 = 0.9 (while the optimal weight λ1 is 0.1), and when the SOC is between 0.3 and 1, the user's choice of optimization weight λ1 will be determined by the EV's SOC, the larger the SOC, the greater the λ1. 4.
Can photovoltaic-energy storage-integrated charging stations improve green and low-carbon energy supply?
The results provide a reference for policymakers and charging facility operators. In this study, an evaluation framework for retrofitting traditional electric vehicle charging stations (EVCSs) into photovoltaic-energy storage-integrated charging stations (PV-ES-I CSs) to improve green and low-carbon energy supply systems is proposed.
