Microgrid Evolution Fuels Smarter Energy Management

Smarter energy management delivers reliability, efficiency and cost savings. From the time when our alarm goes off in the morning to when we turn the lights off at night, we use electrical power. In terms of magnitude, each person in the U.S. spends around $3,052 on electricity (2012 figures). With a population of about 314 million people at the … [Read more...]

How to Optimize Energy Storage in a Microgrid

In this paper, new voltage sensitivity indexes are proposed which can help you optimize energy storage in your microgrid. These indexes are derived from the inverse Jacobian matrix from the Newton-Raphson power flow analysis. After calculating and evaluating these indexes for the studied microgrid, four candidates‘ buses are selected. To verify … [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...]

Case Study: Solar Plus Storage for Caribbean Desalination Plant

Amid the Caribbean energy crisis and high energy prices large consumers of power are looking to reduce their energy cost while reducing fossil fuel consumption. One such high power load is the reverse osmosis [RO], desalination plant at the luxury resort CuisinArt on the picturesque island of Anguilla. The resort's desalination plant services the … [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...]

Islands and Microgrids

Islands and microgrids

The traditional electrical grids deployed on remote islands and microgrids includes a single centralized diesel generating station with distribution lines connected to the rest of the island. This configuration is proving to be expensive and unsustainable. Progressive utilities across the World (with support from organizations such as the World … [Read more...]

Island Microgrids Power the Pacific

island microgrids

The switch over to distributed and renewable energy systems is about more than just cutting loose from fossil fuels and embracing new energy sources. The clean energy change-over is demanding new models for electricity generation, and inverting relationships between producers, consumers and infrastructure operators. The monolithic … [Read more...]
