How Specialized Microgrids can Rapidly Enable a Low Carbon Electricity Network

The U.S. Department of Energy has declared that we are in the midst of a revolution toward a low carbon economy. The transition to renewable generation has begun in earnest, and it is now a matter of time before more energy is generated through clean sources than by burning fossil fuels. How quickly this transition happens depends upon our ability … [Read more...]

Microgrid Knowledge Survey 2016

microgrid survey

We conducted the Microgrid Knowledge survey to gauge market perceptions about the microgrid landscape and its players, markets, and policies. There were 244 responses from microgrid developers, utilities, large energy customers, policymakers, regulators, investors and others. Here are some of the topics we explore in the report. The Microgrid … [Read more...]

We see requests for microgrids services growing across the United States and are excited to have experts on our team who are leaders in the use of the advanced technologies required for their successful … [Read more...]

Lessons Learned Implementing an IEC 61850-based Microgrid Power- Management System

A North American oil refinery recently improved on-site power system reliability by installing a new utility ring-bus substation, a new utility interconnect substation, four new medium voltage distribution switchgear lineups, and separating two on-site 14.9 MVA cogeneration units onto dedicated buses in our management system . The refinery also … [Read more...]

Test & Implementation Framework for IEC 61850-based Microgrid Power Management Systems

Test the Solution  - We carefully planned the FAT to verify secure microgrid power management system operation in normal operation for the design contingencies and under the variety of failure and equipment-outage scenarios identified earlier. Each individual device was power cycled under normal, non-fault conditions. Communication channels were … [Read more...]

Oasis Microgrids Speed Recovery from Large-Scale System Events

In addition to preparing the utility response to a Large-Scale System Events, the planning and preparation activities have these additional immediate benefits to the utility and its customers: • Preparing and documenting the system inventory offers improved awareness of the system assets and their condition. • Oasis system performance studies … [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...]

Microgrid Financing
