With the rapid expansion of new energy, there is an urgent need to enhance the frequency stability of the power system. The energy storage (ES) stations make it possible effectively. However, the frequency regulation (FR) demand distribution ignores the influence caused by various resources with different characteristics in traditional strategies.
Various energy storage systems (ESS) methods support frequency regulation services, each addressing specific grid stability needs. Batteries are highly efficient with rapid response capabilities, ideal for mitigating short-term frequency fluctuations.
The frequency regulation power optimization framework for multiple resources is proposed. The cost, revenue, and performance indicators of hybrid energy storage during the regulation process are analyzed. The comprehensive efficiency evaluation system of energy storage by evaluating and weighing methods is established.
Hybrid energy storage systems that combine different ESS technologies leverage the strengths of each component to provide a balanced solution for LFC. For example, battery–supercapacitor hybrids offer both high energy density and quick response, making them suitable for grids with significant renewable energy sources .
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
