Name： Industrial energy storage

Case description:

The load is 300kVA, the main load is air conditioning, lighting, and production equipment. Summer and winter consume the most electricity.

Photovoltaic power 10kW, energy storage battery 14kWh, as a demonstration project to save electricity costs.

Mains, photovoltaic and energy storage are connected to the grid.

Main products:

The equipment mainly includes photovoltaic panels, inverters, energy storage battery cabinets, monitoring computers, microgrid controllers, communication gateways, etc.

Control Strategy:

The controller is responsible for the regulation of mains, photovoltaic and energy storage. The control strategy is:

1. The energy storage battery is charged and discharged according to the set time period, charging at night and discharging during the day. The cost saving is the electricity price difference between peak and valley periods.

2. Power adjustment to realize optical and storage coordination. When the load is low and the light is sufficient, the remaining power is stored in the battery to prevent reverse power transmission to the grid.

3. The microgrid monitoring system manages the power supply and load.

Main function and screens:

The monitoring center monitors equipment operating parameters, adjusts control strategies, displays alarms, records data, analyzes data, and releases cloud data. The database is deployed on the public cloud or private cloud. Users can view device data and alarm information through mobile phones, tablets, and portable computers through web pages and APPs.
