Centralised management system for renewable energy plants
Power plant controller
The purpose of the control module is to achieve perfect integration of the plant within the electrical distribution grid and facilitate receiving, executing and following instructions received via the corresponding energy regulation body.
Using advanced and adaptable closed loop control algorithms, it makes it possible for solar facilities to meet the requirements of the grid operator. And it provides the capability to administer and control energy injection into the grid in accordance with various grid codes.
The Power Plant Controller makes it possible to regulate different parameters, for example:
- Dynamic voltage regulation and/or the power factor regulation of a solar plant at the POI (point of interconnection).
- Power limiting.
- Power injection ramp speed and power reduction controls.
- Frequency control.
- Start-up and stop control.
Main features
- It can communicate with the following devices:
- Metering cell: electric parameters in the plant sub-station.
- BESS system, transformer, switch gear and other devices.
- Communication with converters via Ethernet TCP/IP.
- The module can have a web-based monitoring and control system that lets users:
- Monitor the status of the instructions received by the grid operator and the execution status of the instructions.
- Overview of the current status of the commands.
- Automatic or manual execution of commands received.
- Can execute local instructions.
- History of commands received and executed.
- Control panel with current production data.
- Can export data to CSV files for analysis.
BESS (Battery Storage)
Smart grids are the key for developing renewable energy technology, integrating electric vehicles and improving the efficiency of electric energy efficiency. Consequently, that means drawing attention to a new electrical grid concept consisting of a grid that’s transformed, in terms of both transmission and distribution, using bi-directional communications systems. Furthermore, the concept itself includes several applications that improve the capacity to supervise and monitor power grids. Storage systems that provide stability to the grid and thus increase the penetration of renewable energy come to the fore in smart grids.
Jema can help you develop solutions for a wide range of applications and it can study battery types and appropriate generation sources for every situation and site.
Solutions:
- Time shifting for renewable energy.
- Energy storage systems for stabilising the intermittent generation of renewable energy sources.
- Emergency back-up system in the event of a grid outage.
- Grid services providing frequency and voltage regulation and dynamic voltage support.
- Solar Fuel saver.
