Power Conversion Systems (PCS) are devicesconnected between the battery system and thegrid to achieve bidirectional energy conversion. The Power Conversion System (PCS) serves as a crucial apparatus facilitating the conversion of electrical energy from one form to another, allowing for the storage or release of energy within a battery system. As the Energy Storage System (ESS) emerges as a solution to address energy shortages, the PCS plays a pivotal role in extracting stored energy from the ESS and converting it into the desired form for end-user consumption.
In addition to its primary function of power conversion, a Power Conversion System (PCS) assumes responsibility for regulating the quality of electricity, managing both active and reactive power, and continuously monitoring voltage levels and operational status. Moreover, in the event of a power outage, the PCS safeguards the power system by autonomously activating backup batteries, ensuring uninterrupted operation even in the absence of a primary power source.
