ESS energy storage system

Battery energy storage systems (BESS) are essential components and critical supporting technologies for smart grids and renewable energy power stations, such as wind and solar. They provide various services to the power grid, including peak shaving, frequency regulation, backup power, black start capabilities, and demand response. BESS enhance the flexibility, economy, and safety of traditional power systems while significantly improving the integration of renewable energy sources.

 

Our latest BESS is a state-of-the-art electrochemical energy storage system based on a dynamic energy management system (EMS-GPC). Housed in a 40HQ container, the system includes a battery system, battery management system (BMS), dynamic energy management system (EMS-GPC), power converter system (PCS), environmental control system, and fire-fighting system. The battery system, with a capacity of 3200kWh, can be fully deployed across two 40HQ containers.

Working Mode (PCS)

 

On Grid: The default factory setting of ATESS is: Zero-Export, Load First mode

Zero-Export Zero export function, the excess PV cannot flow to the grid 
Non zero-Export Non-zero export function, the excess PV can flow to the grid 
Load First PV is higher than load consumption, PV will priority supply load, then excess will charge battery. 
PV >load
Load First PV is lower than load consumption, then battery will discharge to offset the shortage part. If battery voltage approaches the under voltage limit, battery will stop discharging, and the load will supply by PV and grid. 
PV <load

 

On Grid: Working Mode - Battery First mode

PV >Battery PV is higher than maximum battery charging power, PV will priority charge battery, then excess will supply load.
PV <Battery PV is lower than battery charging power, PV and grid will charge battery at maximum charging power simultaneously. The load will supply by grid.  

 

On Grid: Working Mode - Economy mode

During Off-peak The working mode is same as battery-first mode
During Mid-peak  1, Battery doesn’t discharge, grid won’t charge battery.
2, PV is higher than load consumption, PV will priority supply load, and then excess will charge battery.
3, PV is lower than load consumption; load will be supplied by PV and grid simultaneously. PV won’t charge battery.
During On-peak  1, Grid won’t charge battery.
2, PV is higher than load consumption, PV will priority supply load, and then excess will charge battery.

3, PV is lower than load consumption,  PV and battery will supply load simultaneously. If battery voltage approaches the under voltage limit, It will stop discharging. Load will be supplied by grid and PV. Grid doesn’t charge battery in this period.

 

On Grid: Working mode - Time schedule mode

PCS Connected to Grid & Battery When PCS is only connected to the grid and battery, set the on-peak period, mid-peak period and off-peak period, battery discharge in on-period, charge the battery in off-peak period, and do not charge and discharge in mid-peak period, the charging and discharging power can be set.

 

On Grid: Working mode - EMS mode

In EMS mode In EMS mode, PCS is fully controlled by EMS for charging and discharging, there is no working logic. 

 

Off-Grid Mode 

Off-Grid  Load is supplied by PV and battery. 

 

DG Mode: Generator connection (dry contact control)

In off grid mode In off-grid mode, when battery voltage is approaching under voltage limit, PCS will close a relay output to start generator. The generator power will be used to supply load and charge battery. When battery is fully charged, PCS will send signal to shut down the generator.
