영문목차

Penetration of distributed solar is set to increase by over 300% in the United States over the next four years, straining existing distribution infrastructure at the local level in at least thirteen states. Secondary distribution grid control equipment, including power electronics-based solutions, represents the best and increasingly most cost-effective technical solution to these problems. GTM Research expects the market for these devices to grow tenfold over the next five years alone.

Secondary distribution control equipment addresses the localized grid stability issues that will continue to impact distribution grids in the near-term as distributed solar penetration continues to grow. Wider deployment of these solutions could drastically improve the way power is distributed while simultaneously increasing operational flexibility. Cost-effective deployment and integration of these solutions into existing distribution grid control architectures will benefit from leading utility efforts to enhance planning and simulation software. This will enable utilities to better direct limited capital budgets to purchase and install the right solution in the most critical locations.
