But few studies have examined their operation in electricity markets.</p> <p style="text-align: justify;">For WISE researchers Claudio Cañizares,…</p></div>Sana SadiqFri, 25 Mar 2022 10:56:57 -0400https://wise.uwaterloo.ca/news1/research-stories/participating_profitably_how_compressed_air_energy_storage_can_make_the_most_of_electricity_marketsOvercoming short-circuit shortcomings on wind farmshttps://wise.uwaterloo.ca/news1/research-stories/overcoming_short_circuit_shortcomings_on_wind_farms<div><p><img src="/.api2/binaries/oGRuYRc55c/thumbnails/iStock-1137394150.jpg?width=300" style="width: 300px; height: auto;" class="fr-fic fr-dib" data-key="oGRuYRc55c" data-contentlength="10455187" data-contenttype="image/jpeg" data-binarylocation="/.api2/binaries/oGRuYRc55c/download/iStock-1137394150.jpg" data-thumbnaillocation="/.api2/binaries/oGRuYRc55c/thumbnails/iStock-1137394150.jpg" data-name="iStock-1137394150.jpg" data-isprofilephoto="false" data-ig-embed-key="oGRuYRc55c"></p> <p id="isPasted" style="text-align: left;">Wind farms contribute an ever-growing share of the energy flowing through the world’s electricity grids. Because those grids have to be stable and reliable, wind farms are required to stay connected even if a short circuit causes the voltage to drop. This prevents a short circuit from knocking out other generators and causing widespread outages.</p> …</div>Sana SadiqWed, 26 Jan 2022 16:10:27 -0500https://wise.uwaterloo.ca/news1/research-stories/overcoming_short_circuit_shortcomings_on_wind_farmsPlotting the path to a hydrogen economyhttps://wise.uwaterloo.ca/news1/research-stories/plotting_the_path_to_a_hydrogen_economy<div><p><img src="/.api2/binaries/ojosWlf7Kt/thumbnails/PIC-1.jpg?width=300" style="width: 300px; height: auto;" class="fr-fic fr-dib" data-key="ojosWlf7Kt" data-contentlength="1060317" data-contenttype="image/jpeg" data-binarylocation="/.api2/binaries/ojosWlf7Kt/download/PIC-1.jpg" data-thumbnaillocation="/.api2/binaries/ojosWlf7Kt/thumbnails/PIC-1.jpg" data-name="PIC-1.jpg" data-isprofilephoto="false" data-ig-embed-key="ojosWlf7Kt">When you burn fossil fuels, the by-products are greenhouse gases and particulates.
