Hybrid Power Systems

HOMER Energy Handpicked News Highlights, Week Ended July 1, 2016

Off-grid home solar-storage, community solar and microgrid projects in Brooklyn, Ontario, Minnesota, Rwanda and Kenya are among the highlight of this week’s microgrid and distributed energy developments.

Remote Utility Projects Fuel 2GW Rise in Global Microgrid Capacity

*NYSERDA

Navigant Research added nearly 1,600 microgrid projects with a combined generation capacity of 15 gigawatts (GW) to its 2Q Microgrid Tracker, an indication of the extent and degree to which stakeholders are turning to distributed zero- and low-emissions microgrids enhance energy security, reliability, efficiency and resiliency and reduce power sector greenhouse gas (GHG) emissions.

RISØ Report Concludes Danvest System Delivers Power Quality in Microgrid Applications

Danish national research institute RISØ, a world leader in setting standards for the modern wind industry, has released a report on power quality in diesel-wind microgrid-based hybrid systems.  RISØ measured performance using a Danvest Hybrid Power Plant running with a Vestas 600kW wind turbine. The institute tested voltage and frequency fluctuations during continuous operation as well as during transitions between different states of operation. The report concludes that frequency and voltage vary very little, both […]

Portugal’s Prime Minister Dr. Antonio Costa joined the President of the Azorean Government Dr. Vasco Cordeiro and other high-level officials May 3 on a tour of what’s billed as the world’s first megawatt-scale, grid-forming renewable energy system.

A Bright Future for Microgrids and Distributed Generation in Australia: Microgrid 2015 Wrap

More than 150 highly engaged people from 10 countries attended HOMER Energy’s 3rd and largest annual microgrid conference in Canberra, Australia on October 14 and 15 2015. The meeting kicked off with an inspiring and motivating opening keynote by Simon Corbell, Deputy Minister of the ACT Government and Minister of Environment and Planning. ACT has chosen to be a leader in Australia, with a goal of 100% renewable energy by 2025. Minister Corbell […]

ABB Microgrid Solution to Boost Renewable Energy Use by Remote Community in Kenya

ABB, the leading power and automation technology group, has won an order from Socabelec East Africa Ltd. to design, supply and install a PowerStore flywheel-based microgrid stabilization solution for the Marsabit wind farm in northern Kenya. The country plans to quadruple its energy output in the next five years bringing on board an additional 5,000 megawatts (MW) of power capacity, with the aim of providing the majority of its approximately 50 million citizens access […]

Village Power – Back to HOMER’s Roots of Remote Hybrid Renewable Microgrids

The HOMER software is now in use throughout the world, for hybrid renewable power systems of all sizes. But HOMER’s roots at the National Renewable Energy Laboratory were in village power, and HOMER Energy has recently been involved with a few village power projects that reminded us that 1.5 billion people still live without electricity, and the recent price increases in diesel fuel have made the transition to renewables far more compelling for […]

Strawman Proposal for a Taxonomy of Renewable Penetration Levels

This strawman taxonomy provides clear distinctions between different levels of renewable penetration.  By basing the criteria on the architecture and control of the power system, it avoids the ambiguity that is inherent in a taxonomy based on the percentage of renewable penetration or contribution.  Not only is the renewable penetration or contribution subject to multiple definitions, but it can vary widely depending on the load shape, characteristics of specific components, and the resource, […]

Call for Papers: Microgrid Deployment Forum

HOMER Energy will convene the Microgrid Deployment Forum 2013 in Cancun, Mexico, November 8 and 9 2013, in conjunction with the Solar World Congress, sponsored by the International Solar Energy Society. The Microgrid Deployment Forum 2013 is a two-day event that carefully examines the business models, optimal technology mix, and critical steps for successfully deploying microgrid systems in remote, island, and off-grid environments. The emphasis is on refining the business model as well […]

The Problem with 100% Renewable Energy

The New York Times reported recently on the work of a group of Stanford researchers, who published a piece in the journal Energy Policy claiming that the main issues with 100% renewables are neither economic nor technical but rather social and political will. Jesse Berst of Smart Grid News countered with a title that included the phrase, “Get real, Stanford.” As experts in the economics of renewable energy, HOMER Energy would like to […]
