Energy refers to resources that can provide energy for work, heat, light or driving machinery, etc. The energy we know includes non-renewable energy such as coal, oil, natural gas, and renewable energy such as solar energy, wind energy, hydropower, biomass energy, in addition to nuclear energy, ocean energy, etc. In this century, it is a very common phenomenon to apply renewable energy to our production and life. In the process of use, in order to better monitor and manage energy equipment and improve the efficiency of user interaction, it is very necessary to convey various parameter information of the equipment to people through the display screen.

This chapter will introduce you to the application of display screens in different energy devices

1. Electric power

Power substation:

• SCADA system (supervisory control and data acquisition): The display screen is used to display the grid operation status, load status,  equipment status, etc.

• Human-machine interface (HMI): The display screen is used to operate and monitor substation equipment to achieve remote control and on-site operation.

Smart meter:

• The display screen is used to display real-time power consumption, cost, power and other information to help users understand and manage power consumption.

Power station control room:

• Large display screen is used to monitor the operating status, output power, efficiency and other key parameters of power generation equipment in real time.

2. Solar

Photovoltaic inverter:

• The display screen is used to display real-time power generation, conversion efficiency, voltage, current and other key parameters for easy monitoring and maintenance.

Solar controller:

• The display screen displays information such as battery status, charging status, load status, etc., which is convenient for users to manage solar energy systems.

3. Wind energy

Wind farm control system:

• The display screen is used to display wind speed, wind direction, power generation, blade status and other information to help optimize the operation of wind turbines.

Inverter and motor controller:

• The display screen is used to display the operating status, fault diagnosis information, etc., to facilitate maintenance and optimize operation.
  

4. Energy storage system

Battery management system (BMS):

• The display screen is used to display the battery status, charging and discharging status, health status, etc., to help manage the performance and life of the battery system.
  

Energy storage inverter:

• The display screen displays information such as charging status, discharging status, system efficiency, etc., to facilitate users to monitor and manage the energy storage system.
  

5. Smart grid

Energy management system (EMS):

• The display screen is used to display real-time energy consumption data, the status of distributed energy, demand response status, etc., to help optimize energy distribution and use.
  

Load control:

• The display screen is used to display and control the operation of each load, optimize power distribution and reduce energy waste.
  

6. New energy vehicles

Charging pile:

• The display screen is used to display information such as charging progress, voltage, current, charging time, etc.
  

• User interface interaction: The display screen is used to select charging mode, payment method, display charging fees, etc.
  

On-board energy management system:

• The display screen is used to display information such as battery status, remaining mileage, energy consumption data, etc., to help drivers manage vehicle energy.
  

7. Industrial energy

Industrial control system:

• The display screen is used to display equipment operating status, energy consumption data, production efficiency, etc., to help optimize industrial processes and save energy.
  

Energy monitoring instrument:

• The display screen is used to display various energy parameters, such as voltage, current, power, frequency, etc., to help companies manage energy efficiency.
  

8. Home energy management

Smart home control panel:

• The display screen is used to display household electricity consumption, solar power generation, energy storage system status, etc., to help users optimize energy use.
  

Smart meter and home energy management system (HEMS):

• The display screen is used to display household energy usage, energy costs and energy-saving suggestions.
  

The application of display screens in energy equipment not only improves the efficiency of energy management and monitoring, but also promotes the intelligent and digital development of energy systems, providing users with more intuitive and convenient operation and information display methods.
