Tender summary

<p>Pre-Solicitation Notice</p> <p>System for Award Management (SAM) Posting</p> <p>Notification of Intent to Publish a Full and Open Competitive Solicitation for</p> <p>DC Filter at NLR&#39;s Flatiron&#39;s Campus</p> <p></p> <p><strong>INTRODUCTION</strong></p> <p>The National Laboratory of the Rockies (NLR) is the U.S. Department of Energy&rsquo;s primary national laboratory for energy systems research and development. As the energy systems laboratory, NLR&rsquo;s unique strength lies in developing and integrating a broad array of energy technologies into robust, resilient systems - bridging foundational research with practical applications to lower energy costs, drive economic growth, bolster national security, and deliver abundant and reliable energy.</p> <p></p> <p><strong>BACKGROUND</strong></p> <p>A DC filter is a powerful tool in power electronics and energy systems research. It can smooth out voltage or current ripples in DC systems and is particularly effective when used in conjunction with a Controllable Grid Interface (CGI) which can dynamically adjust system parameters.&nbsp;</p> <p></p> <p>Procurement of a DC Filter will open a wide range of research opportunities, especially in the context of modern power systems and renewable energy integration. Key research areas include power quality improvement, grid-forming and grid-following control, advanced control algorithms, DC microgrid research, and hardware-in-the-loop simulations.</p> <p></p> <p><strong>DESCRIPTION: </strong></p> <p>NLR intends to publicly publish for a period of 15 calendar days a competitive solicitation for the following:</p> <p>DC Filter - This project seeks to add a 4kA DC Filter within the CGI Yard.
