A Test Model of a Power Grid With Battery Energy Storage and Wide-Area Monitoring

This paper presents a test model for investigating how to coordinate a power grid and energy storage systems (ESSs) by wide-area monitoring (WAM). It consists of three parts: first, a model of a power grid containing different types of generators, loads, and transmission network; second, a model of lithium-ion battery ESSs; and third, a model of multivariate statistical analysis based WAM built to capture the grid information for guiding the operation of ESSs. Simulation studies using a reduced equivalent model specifically built for a UK power grid enhanced with lithium-ion battery ESSs and WAM illustrate the way in which WAM can coordinate a power grid and ESSs, and also demonstrate the benefit of ESSs on a power grid.
