The power systems are responsible for energy transportation in the form of electricity, are subjected to anumber of disturbances such as frequency variation or voltage fluctuation. These may impact to the devices which we areconnected to the network. An effective storage system such as battery energy storage systems (BESS) may bring thenetwork many advantageous. There are several models to examine the BESS for micro grid stability analysis such asdetailed model, ideal dc link model, and an average model .All the models share the same parameters and the controlstrategy. In this paper a Dependent Source Model (DSM) is proposed for modeling the battery energy storage system(BESS) for micro grid stability. Here in the proposed model, switches are replaced by dependent voltage and currentsources and the control system remains the same. To obtain optimum PI controller settings for a non-linear process aParticle Swarm Optimization (PSO) technique is used. In this paper optimum values of PI controller settings are foundand it is proved that the PSO based tuned PI values in the DSM model gives better results than the gain schedulingmethods.
