For the smart grid arrangement a battery energy storage system is important equipment of renewable energy resources. In this paper we will have a discussion on active power control in a battery storage system with a topology of cascaded multi level inverter with pulse width modulation switching technique. Multilevel inverters have been attracting in favor of academia as well as industry in the recent decade for high-power and medium-voltage energy control. A battery energy storage system (BESS), combining battery packs with a power converter and control, should be installed in the vicinity of an intermittent energy source. Here we can control the active power as individually in a converter cell battery arrangement unit, by this we can have a advantage of charging and discharging of a battery units at different power levels. The charging/discharging of the battery in a dc form can be shown in this paper. From the controlling of active power as in a individual converter cells we will get maximum utilization of battery power to the load as required. If we will get a less harmonic content in the output voltage definitely we can improve the utilization part, so this can be obtain by getting the multiple level of voltage as approximately sinusoidal with maximum reduction of harmonics. The simulation results for this proposed system have been shown in this and also multiple levels of voltages in output can be shown in this paper.
