Grid expansion isn&#8217;t an option\u2014in most cases, the economics don&#8217;t make sense.<\/p>\n<p>Where the main grid falls short, such as in\u00a0isolated communities\u00a0or when the lights go out from extreme weather, microgrids are a solution for more resilient power. These decentralized, self-sufficient\u00a0energy\u00a0hubs can run independently or connect to the larger grid. Yet one lingering hurdle is microgrid design. Getting the mix of power sources right involves complex tradeoffs between risk tolerance, cost, and going green.<\/p>\n<p>New research from a team at Pacific Northwest National Laboratory (PNNL) shows that resilient, hyper-local microgrids provide economic value, if designed with the right mix of power sources.

Less than a third of that power comes from renewables, while the rest comes from fuel-powered generators.<\/p>\n<p>Yet, the things that make the Hawaiian Islands special\u2014the ocean breeze, sun, and waves\u2014all bode well for a microgrid test case. Moloka&#8217;i&#8217;s aim to kick the fuel-burning habit is something many other island or rural communities grapple with.<\/p>\n<p>&#8220;Microgrid design is complicated. A lot of communities aren&#8217;t set up to develop something like that,&#8221; said Dhruv Bhatnagar, a PNNL mechanical engineer who was part of the PNNL research team focused on Moloka&#8217;i as part of a larger evaluation of marine energy resources.<\/p>\n<div style=\"width: 640px;\" class=\"wp-video\"><video class=\"wp-video-shortcode\" id=\"video-376699-1\" width=\"640\" height=\"360\" preload=\"metadata\" controls=\"controls\"><source type=\"video\/mp4\" src=\"https:\/\/scx2.b-cdn.net\/gfx\/video\/2021\/are-microgrids-a-key-t.mp4?_=1\" \/><a href=\"https:\/\/scx2.b-cdn.net\/gfx\/video\/2021\/are-microgrids-a-key-t.mp4\">https:\/\/scx2.b-cdn.net\/gfx\/video\/2021\/are-microgrids-a-key-t.mp4<\/a><\/video><\/div>\n<figure class=\"mb-4\"><figcaption class=\"text-darken text-low-up mt-4\">Microgrids are typically powered by solar and\/or wind, which use extra power to charge batteries, plus a generator for backup.

Typically, microgrids include solar and\/or wind, which charge batteries, plus a diesel generator for backup.<\/p>\n<div class=\"article-banner w-100 mb-4\"><\/div>\n<p>Since Moloka&#8217;i&#8217;s goal was zero emissions, researchers predicted what would happen if existing\u00a0diesel generators\u00a0were swapped with marine energy. When added to the mix of wind and solar, marine energy not only ramps up resiliency, but it also slashes reliance on fuel.<\/p>\n<p>To meet the zero emissions goal, the research team found that using marine energy can cut the need to build solar and wind up to 50% compared to not including marine energy in the portfolio, plus less battery storage is needed. That&#8217;s good <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a> for communities since batteries are expensive. Also, less emphasis on solar means a reduced land-use footprint. And space is a big deal on a small island.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Resilient_microgrids_to_rebound_faster_longer\"><\/span><b>Resilient microgrids to rebound faster, longer<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>When Hurricane Sandy slammed into the Eastern Seaboard in 2012, the damage was so significant, parts of New York and New Jersey were without power for months after the storm. Yet a microgrid at Princeton University in New Jersey kept the lights on for emergency workers and at key facilities.<\/p>\n<p>There is growing interest in designing microgrids to power things like hospitals, shelters, or police stations during emergencies. Yet microgrid design tends to focus on minimizing cost rather than enhancing resiliency, which means rebounding quickly when the power goes off. But the cheapest solution isn&#8217;t always the best.<\/p>\n<p>&#8220;It&#8217;s hard to put a price tag on resiliency,&#8221; said Sarah Newman, a PNNL data scientist who led a study evaluating microgrid design for U.S. Army posts, which need to be self-sufficient for longer durations. For example, a hospital will place more value on reliable, resilient energy during disasters, as opposed to a homeowner who might be able to go a few hours without power.<\/p>\n<figure style=\"width: 1980px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2021\/are-microgrids-a-key-t-1.jpg\" alt=\"\" width=\"1980\" height=\"1320\" \/><figcaption class=\"wp-caption-text\">Battery storage at Pacific Northwest National Laboratory\u2019s solar array.

Generators are critical in bridging gaps when batteries aren&#8217;t fully charged, such as cloudy days, or when energy demand is high and excess can&#8217;t be saved.<\/p>\n<p>Newman and her team predicted everything from optimal generator sizes and how much fuel they&#8217;d need to store to energy use in different types of buildings, and even solar patterns and weather in different states.<\/p>\n<p>They found that in some cases, the generators aren&#8217;t big enough for the microgrid to be resilient during a variety of outage situations. Plus, the generators need up to 30% more fuel than previously predicted if extreme weather isn&#8217;t accounted for during design. If that extra fuel isn&#8217;t planned for, then the microgrid won&#8217;t be able to meet the energy demand.<\/p>\n<p>&#8220;Stopping after a week and a half may not be an option when a\u00a0microgrid\u00a0is the backup for critical facilities,&#8221; said Newman. &#8220;This underscores how important designing microgrids around resiliency actually is.&#8221;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Microgrid_modeling\"><\/span><b>Microgrid modeling<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The modeling work being done by PNNL can help decision makers weigh tradeoffs and ultimately design microgrids that are more likely to keep the lights on during an emergency or\u00a0power\u00a0areas without access to a main grid.
