Abstract: The large-scale use of PV (solar) technologies creates a large number of constraints on grid flexibility because of the intermittence and stochasticity of solar irradiance during fast weather transients. The need for the integration of a Battery Energy Storage System (BESS) is very much required to do away with the occurrence of voltage ripples, power imbalance locally and to avoid the occurrence of active frequency trips across the internal conversion links. This paper describes in detail the design evaluation for a grid-tied Solar-BESS system, including the basic functions of the moving-average power smoothing and the dual closed-loop DC-bus voltage clamping. The micro grid uses a bidirectional buck-boost converter topology to interface a lithium-ion battery bank with a common high voltage DC link, thereby avoiding transient stress of the inverter components used downstream in the micro grid. Parametric limits are applied to help maintain battery SOHC limits and meet IEEE 519 harmonic limits. The entire framework can be used as an established, low cost engineering baseline for improving renewables penetration in regional distribution networks.
