Integrated DER/Grid use optimization through grid-scale electricity storage

This invention presents an integrated strategy to reduce end-user electricity costs and grid carbon emissions by efficiently utilizing Distributed Energy Resources (DER) and grid-scale electrical energy storage systems, such as batteries. The system optimizes the flow of energy between these two components to enhance energy resilience and cost efficiency while supporting the transition to low carbon transportation sector.

Description

This invention offers a strategy to reduce the levelized cost of electricity and carbon emissions from the electric grid by efficiently using renewable energy sources, like solar power, alongside large-scale energy storage systems such as batteries. As demand for electricity grows, particularly with the increased use of electric vehicles, the system ensures energy is managed effectively to enhance energy resilience and cost minimization. By bouncing energy generation from renewable sources with stored energy, the system optimizes power distribution to minimize the carbon footprint of the grid. It assesses the energy needs of electric truck fleets and strategically manages renewable energy and storage systems to ensure reliability. This approach supports a more sustainable and energy-resilient infrastructure while maintaining efficiency and cost-effectiveness.
