What are the implications of electrical energy storage systems for the future of the electric grid?0 answersElectrical energy storage systems (ESSs) have significant implications for the future of the electric grid. ESSs help absorb and release energy when needed, making surplus energy usable and equivalent to traditional energy sources like fossil fuels. They enable the integration of fluctuating renewable energy sources and provide demand-adapted energy. ESSs can provide multiple services throughout the electricity supply chain, including mitigating the intermittency of renewables, improving power quality, and enabling various smart grid applications. The future grid will rely on the coordinated operation of ESSs with other grid entities, requiring robust cyberphysical security measures. ESSs are increasingly deployed in transmission and distribution grids to improve renewable energy penetration. Cost-benefit analysis and market policies play a crucial role in the deployment and participation of ESSs in wholesale markets. Future research should focus on developing decision-making tools, performance models, market frameworks, and cost-benefit analysis to enhance the performance and profitability of ESSs for grid applications.
