In this video explainer, we demystify the Power Conversion System (PCS) at the heart of modern Battery Energy Storage Systems (BESS). The PCS is the crucial component that converts DC power from the batteries into AC power for the grid (and vice versa), enabling efficient charging and discharging of stored energy. BESS SCADA (Supervisory Control and Data Acquisition) systems and other renewable energy SCADA platforms (such as a solar farm SCADA system) rely on the PCS as a critical link between battery storage and the power grid. We also explore how the BESS PPC (Power Plant Controller) coordinates with the PCS to maintain grid stability and optimize performance. Whether you’re an industry professional or a curious newcomer, this engaging explanation offers clear insights into how BESS technology works behind the scenes.
