Future-Proofing Smart Grid Infrastructure Meter Designs
According to the International Energy Agency, world electricity demand is projected to increase by nearly 80% over the years 2012 to 2040. Modernization, expansion and decentralization of the electricity infrastructure for improved robustness and resiliency is a clear imperative, with the World Economic Forum recently calling for transformational investments exceeding $7.6 trillion over the next 25 years.
With the power grid infrastructure progressively more digitized and connected, ensuring the reliable and secure flow of digital communications is critical. Smart meters are an integral part of the smart grid infrastructure, whether in a power substation or residential setting, enabling the real-time measurements needed to monitor equipment health, grid congestion and stability, and system control. The distributed energy flows characteristic of smart grid infrastructure create network stability concerns, making network timing, security and reliability more imperative than ever before. While ensuring smart grid security and reliability is without question, less understood is that the infrastructure’s connectivity makes network time dependency much more critical.

Power Generation Control Solutions
Reliability, high availability and seamless redundancy are critical requirements for the modern smart energy grid. Secure control systems, as well as protection of physical infrastructure and against cyber security threats are equally important as the grid continues evolving to increase system efficiencies and consumer energy use.
For power generation control – applicable to Doubly Attached Nodes with HSR (DANH), Intelligent Electronic Devices (IED) and Redundant Boxes – Microsemi offers lowest power solutions with instant-on functions and security features.

Power Substation Synchrophasor Solutions
Phasor measurement units (PMUs), or synchrophasors, are essential elements of the modern smart grid. Synchrophasors enable real-time measurement data alignment of multiple remote points across the grid, for a precise and global snapshot view of the entire power system. Whereas typical supervisory control and data acquisition (SCADA) systems use unsynchronized data points collected centrally every few seconds to calculate system state, synchrophasors enable dynamic, real-time system state measurement.
Phasor measurements are time-stamped based on coordinated universal time (UTC), so that PMU-collected data (whether in different locations or with different owners) can be synchronized and time-aligned. This comprehensive, real-time monitoring and analysis is vital for rapid identification of grid condition changes, enabling better maintenance and protection of grid reliability.

Residential Smart Meter Solutions (Water, Gas)
As utilities deploy advanced metering infrastructure (AMI) across their distribution grids, the customer-related data can be now remotely monitored. Smart meters enable two-way communication between the meter and the central system employed by the utilities. Typically, when deploying water and gas meters the utilities face challenges to provide power to the wireless sensors so an efficient, battery based low power sensor design is required. The diagram depicted here shows the implementation example of a generic wireless water and gas meter using solar energy to provide energy to an embedded rechargeable energy storage device.
