Intelligent ways to Save Energy!
Smart Energy Governments worldwide are mandating improved energy efficiency, requiring an investment in the new smart grid and smart energy management structure. The goal is to create a smart grid that will change the way power is deployed for sustainable energy around the world.
- Lower system cost: Required to reduce time to market, R&D investment and BOM costs while adding features for smart grid requirements
- Low (system) power: Must have efficient metering code to enable energy calculations at low processing speeds for meters supported by capacitive supplies
- Data preservation during fail or brownout events: Low-power, real-time clock with the ability to switch to battery supply, on-chip clock compensation, calendaring or an internal clock if the external crystal fails
- Meter tampering: Requires the ability to time-stamp even if supply is disconnected due to tampering
- Increased meter complexity for smart metering communication, which requires more GPIOs and serial communication modules (I2 C, SCI and SPI)
- Aggregate information from individual meters and communicate usage to utility sub via power line communication in order to regulate energy usage.
