PQ control is one of the most common strategies for ESS connected to the grid. It focuses on controlling the active power (P) and reactive power (Q) output of the ESS independently. . Configuring an energy storage system may allow that the grid output is fallen into a specified interval for the purpose of reduction in grid transmission capacity. Each strategy has unique characteristics, benefits, and suitable application scenarios. The. . Three-Phase Four-Leg (3P4L) Inverter is getting so much attention due to its ability to deal with unbalanced AC voltage sources that can be caused by grid/load faults. Recently, the flexibility of this converter to connect both the 1-phase and 3-phase grid systems in an AC battery application has. . Based on the power hypothesis of feed-forward decoupling, PQ control is typical of the micro network control strategy, through the SPLL and d–q trans-formation module power and power factor control module and current control module to establish PQ control model, and in the original basis of. . The invention relates to a three-phase inverter control technology, and aims to provide a method for PQ control of an energy storage inverter in a grid-connected state.
