Abstract-The utilization of inverters for the interconnection of distributed generators to the grid requires application of control systems capable of regulating the active and reactive output current, ensuring high power quality levels and achieving relative immunity to grid perturbations.
V. This paper proposes a control strategy for a voltage source inverter with an LCL output filter, suitable for interfacing dc voltage sources to the grid. The proposed control system is simple, exhibits satisfactory transient response and robustness to grid impedance variations.
Simple strategies focus on the direct control of a single variable, such as the output or inverter current (respectively at grid- or inverter-side of the filter) . A common approach comprises an outer control loop for capacitor voltage control and an inner control loop for the inverter current.
There are three methods to enhance the power capacity: 1) paralleling multiple phase in an inverter [3, 4, 5, 6], 2) paralleling multiple inverters, and 3) paralleling multiple IPT systems . Paralleling inverters or IPT systems requires multiple dc sources or transmitting coils, which can lead to high cost and system design complexity.
