Renewable Energy Integration
Meet the challenges of integrating renewable energy sources—while ensuring system stability and delivering reliable electric power.
Ensure Transmission System Stability
As renewable energy sources continue to replace traditional fossil fuel generation capacity, care must be taken to ensure that transmission systems remain stable and new generation sources are properly integrated with existing sources.
Integrating wind and solar generation poses particular challenges for transmission system operators, who must deliver uninterrupted bulk electric power despite the intermittent and variable nature of these sources.
SEL designs and commissions wide-area protection and control systems—also commonly called special protection schemes (SPS) and remedial action schemes (RAS)—that ensure transmission system stability and provide wide-area situational awareness.
Enhancing the stability and capacity of existing transmission lines can potentially free up billions of dollars in capital expenditures. In some cases, utilities can operate transmission corridors at a higher capacity after the RAS/SPS is implemented, increasing revenue and freeing up capital expenditure.
