Several key challenges arise when grids are powered by a high percentage of renewables. These include issues with intermittency, ramp rate control, frequency management, and low inertia. These issues are particularly acute on smaller grids, such as on geographically or electrically islanded systems.
A battery energy storage system (BESS) can solve these issues when paired with a high-speed inverter and managed by a grid-aware high-speed controller. This technology combination is being tested and proven in island environments and the results offer valuable insights for grid operators of larger grids who are just beginning to experience issues related to the influx of renewables.
PXiSE CEO Tim Allen explores the role of BESS in combatting issues brought on by renewables in an article on POWERGRID International.
