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

danvest

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 […]

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

Village-Power-Metering

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

Wind turbines at sunset

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, […]
