The Smart Grid Foundation

From Meters to Minds: Sensing and Awareness

Advanced metering infrastructure, edge sensors, and synchrophasors give operators real-time visibility into voltage, frequency, and flows. That situational awareness is the bedrock for integrating variable renewables without sacrificing reliability or safety.

Two-Way Power and Communication

Unlike traditional one-way grids, smart grids enable bi-directional power and data. Rooftop solar, batteries, and EVs can both consume and provide services, while secure communications coordinate thousands of distributed energy resources at once.

A Neighborhood Story

On a breezy afternoon, a coastal neighborhood’s solar peaked just as demand surged. Automated controls shifted flexible loads and battery dispatch within seconds, keeping lights steady—and neighbors barely noticed anything beyond the sunshine.

Integrating Renewables at Scale

Grid-Forming Inverters for Stability

Modern inverters can establish voltage and frequency references, enabling stable operation even when conventional synchronous machines are scarce. This grid-forming capability helps renewables ride through disturbances and support black-start and islanded operations.

Forecasting Meets Flexible Scheduling

Machine learning improves wind and solar forecasts, while probabilistic scheduling plans for uncertainty. Operators combine day-ahead predictions with intra-day updates, using batteries and demand response to balance deviations without excessive curtailment.

Volt/VAR and Curtailment Minimization

Smart inverters provide reactive power and voltage support, reducing congestion and losses. Coordinated Volt/VAR optimization, dynamic setpoints, and flexible interconnection rules help maximize renewable hosting capacity while minimizing unnecessary curtailment.

Time-of-use and real-time pricing incentivize shifting consumption to cleaner, cheaper hours. Smart thermostats, water heaters, and chargers automate responses, delivering comfort while aligning loads with solar peaks and wind-rich nighttime periods.

Home energy management systems coordinate rooftop solar, batteries, and appliances. With standards-based control, prosumers can deliver peak shaving, frequency response, and voltage support—earning credits while supporting local reliability and cleaner energy usage.

The Martins enrolled their heat pump and EV charger. During a critical peak, automated controls pre-cooled rooms and delayed charging, saving money and emissions. They celebrated with an evening walk under still-spinning turbines.

Storage, EVs, and Vehicle-to-Grid

Grid-scale and community batteries deliver frequency response and ramping within seconds. Their agility smooths wind lulls and cloud transients, reducing reliance on peaker plants and cutting both costs and carbon intensity meaningfully.

Phasor measurement units stream time-synchronized voltage and current angles, revealing oscillations and stability margins. These insights guide renewable dispatch, remedial action schemes, and smarter limits that preserve safety while increasing transfer capacity.

Data, AI, and Digital Twins

Resilience and Community Microgrids

Microgrids operate seamlessly with the main grid, then island during faults. With grid-forming inverters, protection schemes, and standardized interfaces, communities enjoy independence when necessary without sacrificing everyday collaboration benefits.

Standards, Policy, and Cybersecurity

IEEE 1547 guides inverter capabilities like ride-through and reactive power. IEC 61850 enables substation interoperability. Adopting common profiles ensures DER fleets can plug-and-play while supporting voltage, frequency, and protection coordination.

Standards, Policy, and Cybersecurity

Policies such as FERC Order 2222 enable aggregated distributed energy resources to participate in wholesale markets. This unlocks new revenue streams for prosumers and expands flexibility options that accelerate renewable integration at scale.
