What’s Next as NREL Ups the IQ of the Microgrid Controller?

microgrid controller

The National Renewable Energy Laboratory (NREL) is expected to release results soon from a microgrid controller competition designed to further develop the “brain” of the microgrid. NREL will announce a winner and publish results for the microgrid industry to use in advancing the all-important intelligence that distinguishes microgrids from … [Read more...]

No Microgrids at the Busiest Airport in the World?

microgrids

Like Puerto Rico, the Hartsfield-Jackson Atlanta International Airport found out the hard way why microgrids are a good insurance policy. The world’s busiest airport suffered an 11-hour power outage on Sunday, delaying over a thousand flights and leaving passengers stranded for hours in darkened terminals or seated in planes. Georgia … [Read more...]

Design and Development of a Microgrid Control System

This paper presents a centralized microgrid control system for effective operation of wind turbines and diesel engines coupled to a flywheel electrical storage component on Saint Paul Island. The wind turbines have sufficient capacity to support the entire island without using the diesel engines, allowing the formation of an islanded power system … [Read more...]

Duke Energy Builds Microgrid Control System

Duke Energy Corporation is an energy utility that serves 7.4 million electric customers in six states in the Southeast and Midwest regions of the United States. Prompted by recurring severe weather events and a goal of incorporating more renewable generation into the electric power grid, Duke Energy decided to integrate their existing renewable … [Read more...]

Protection, Control, Automation, and Integration for Off-Grid Solar-Powered Microgrids in Mexico

In 2012, Comisión Federal de Electricidad (CFE), the national Mexican electric utility, provided electric service to 98.11 percent of the country.  However, rural communities in Mexico (mainly isolated indigenous communities) still lack electric service. Conventional electrification is neither practical nor affordable for these communities that are … [Read more...]

Implementing a Microgrid Using Standard Utility Control Equipment

Recent weather events have proven that a single storm can cause billions of dollars of damage to the electrical power grid as well as significant power outage-related costs. As a result, utilities across the United States are working to make their microgrid services more resilient. This alone is a challenge, but some utilities also face state-level … [Read more...]

UC San Diego Optimizes Microgrid System With SEL POWERMAX and Protection Relays

The UC San Diego microgrid has over 33 megawatts of installed onsite generation, including gas-turbine cogeneration and storage, solar, fuel cell, steam, and diesel. The onsite generation is only enough to support critical loads. To cover the rest of their load demand, the university purchases additional electric power from SDG&E. The idea … [Read more...]
