Abstract. This paper presents the design and simulation of a bi-directional battery charging and discharging converter capable of interacting with the grid.
Traditionally battery-charging current is independent of the grid operating conditions, as the battery operates at a constant current constant voltage (CC–CV) while charging. On the other hand, if the variable load is connected to the grid, the battery will follow the dynamic constant current-constant voltage (DCC–CV) charging process.
A model for PV-Wind-Grid-integrated EV Charging System with battery is developed. The model optimizes the proposed system's operation while minimizing costs. The system is using peer-to-peer energy sharing between the EV sharing infrastructure. Simulation is performed using MATLAB software.
Intelligent charging and discharging of the storage battery: The hybrid solar inverter can intelligently control the charging and discharging process of the battery according to the battery status (e.g., SOC, i.e., the percentage of remaining battery power) and the grid electricity price.
Grid voltage and current during discharging mode (V2G) Once the charger is connected to the grid, the voltage across the DC link capacitor gradually increases, as demonstrated in Fig. 7. The voltage attains its target level of 400V within an impressive timeframe of under 0.4 seconds, devoid of any noticeable overshoot.
Flexible switching between grid-connected and off-grid: Although grid-connected PV systems are usually designed to operate in parallel with the grid, under certain special circumstances (e.g., grid faults, blackouts, etc.), hybrid solar inverters should have the ability to operate off-grid.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually.
