The project has 26 smaller systems at different buildings/ areas. These multiple buildings have to be integrated into one larger system due to Zero Export function requirement as per Suruhanjaya Tenaga self-consumption guideline.
The challenge is to have a main system control that can specifically instruct and control individual smaller systems to the Zero Export function requirement.
How do we solve it?
By proposing an additional Master-Slave system control solution.
A master controller will receive input on how much consumption is needed at the premise, and thus control each and every individual system generation to match the required consumption.
The system generation can be controlled regardless of the number of smaller systems to avoid export to grid and also non-compliance to ST self-consumption guideline.
