Elements of a microgrid, by Willdan

Community microgrids are robust local energy networks that operate separately from the surrounding electric grid during extreme weather or other emergencies. These networks provide heat and power from local generation sources to sustain the operation of hospitals, first-responder requirements, emergency shelters, and community residences. Since 2008, our staff played a key role in the feasibility, design, management, and measurement and verification (M&V) of the smarter, more sustainable power grid at the campus of the Illinois Institute of Technology (IIT) in Chicago—a world-class $14 million project called IIT Perfect Power.

Microgrid-Related Practices

Willdan's team expertise lies in applying optimization algorithms to solve challenges that result in the secure and economical operation of power systems through congestion analysis, transmission expansion planning, renewable energy integration analysis, and microgrid studies.

Willdan's team of national and international experts includes Silver Spring Networks, OSI software, S&C Electric DER solutions, and the Galvin Center for Electricity Innovation at the Illinois Institute of Technology.

Microgrid Feasibility and Planning Studies
The Advanced Grid Technology (AGT) team performs microgrid feasibility analysis studies to identify microgrid capabilities, develop technical design cost and system configuration, and assess microgrid commercial and financial feasibility cost and benefit.
Microgrid Design
The team has specialized expertise in developing and applying state-of-art microgrid grid technologies to resolve the most important challenges operators or customers may encounter.
Microgrid Operation and Analysis
The team has experience in applying a high-reliability distribution system for enhancing reliability, new sustainable energy sources (roof-top solar panels, wind generation units, flow batteries and charging stations for electric vehicles), and smart building automation technology (building controllers, Zigbee sensors, controllable loads) for energy efficiency and demand response.

Representative Project: 9 NY Prize Community Microgrid Assessments

The Willdan team was competitively selected as part of the State of New York's innovative $40 million PRIZE program to perform microgrid feasibility assessments for nine communities in New York, most of which are nearing completion.
