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...]

Special Report on Fuel Cell Microgrids

microgrid and fuel cell

Fuel cell microgrids are on the rise, the result of a natural pairing of two technologies-fuel cells and microgrids- that serve a mutual mission. Together, they meet today’s demand for energy that is cost-competitive, highly reliable, clean, quiet, contained, modular, scalable and community-friendly. Once futuristic, both technologies find … [Read more...]

Solar Plus Storage

There is a lot of talk about solar plus storage. Yet, it's important to know that by adding energy storage with a DC-to-DC converter you can maximize production & profits of installed North America PV base. Traditional storage plus solar (PV) applications have involved the coupling of independent storage and PV inverters at an AC bus, or … [Read more...]

Solar Plus Energy Storage

Solar is good, yet solar plus energy storage is great. However it is important to understand the options for adding energy storage if you want to maximize energy production and revenues from utility scale PV arrays. North America currently has over 20 GW of installed utility-scale PV generation with 2016 seeing the largest amount of PV installed … [Read more...]

Microgrid Energy Storage Beyond Four Hours

This paper aims to capture and foster current thinking on new and emerging use cases for microgrid energy storage, and in particular the growing need to combine energy and power applications into a single flexible and valuable long-duration storage asset. This market evolution is significant because it increasingly requires storage asset … [Read more...]

Reciprocating Engine Generators and Microgrids: The Last Defense Against a Power Outage

reciprocating engines and microgrids

Reciprocating engine generators are becoming increasingly important to help solve three contemporary energy problems. The first problem occurs in developed areas like North America, where electric reliability is crucial as the economy grows ever more Internet-based. The second problem can be found in remote regions of the world, where no … [Read more...]

Microgrid Knowledge Guide to Gas Turbine Microgrids

gas turbine microgrid

Movement is a foot worldwide to bring new intelligence to conventional or ‘dumb’ generation. The gas turbine microgrid is central to this smartening of power generation. The term dumb generation describes the kind of conventional power plants, wind turbines or solar panels that have been used for decades. They produce megawatts, but do nothing … [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...]
