Abstract: This paper presents control algorithms and sizing strategies for using energy storage to manage energy imbalance for variable generation resources. The control objective is to minimize the hourly generation imbalance between the actual and the scheduled generation of wind farms.
In this paper, the battery energy storage technology is applied to the traditional EV (electric vehicle) charging piles to build a new EV charging pile with integrated charging, discharging, and storage; Multisim software is used to build an EV charging model in order to simulate the charge control guidance module.
An electric vehicle charging pile provides two charging modes: regular charging and quick charging. Users can swipe a specific charging card on the human-computer interaction interface provided by the charging pile to carry out corresponding operations such as selecting the charging mode, charging time, and cost data printing, etc.
The simulation results of this paper show that: (1) Enough output power can be provided to meet the design and use requirements of the energy-storage charging pile; (2) the control guidance circuit can meet the requirements of the charging pile; (3) during the switching process of charging pile connection state, the voltage state changes smoothly.
The minimum installation distances for the charging pile are: no less than 700 mm from the back door to the wall, and no less than 500 mm from the side face to the wall. (5) The canopy is built together with the charging pile. (6) This installation method is just a sample for reference.
The traditional charging pile management system usually only focuses on the basic charging function, which has problems such as single system function, poor user experience, and inconvenient management.
