HOME / Bidirectional Power Control For A Three Phase - KKA Industrial Storage
The Inverter Control is widely used in several kinds of energy conversion, for example, a motor control (electric energy to motive power) for an air conditioning system or washing machines, and so on, IH cooking machines (electricity to heat), and power conditioners which convert solar-generated electric power to home AC power supply (electric to electric).
Inverter controller, which ensure the control of active and reactive power generated to the grid; the control of DC-link voltage; high quality of the injected power and grid synchronization. The control strategy applied to the inverter mainly of two cascaded loops.
Photovoltaic (PV) inverters convert DC power generated by solar panels into AC power for grid connection. Uninterruptible Power Supplies (UPS) provide backup power during grid outages, ensuring the continuity of critical operations. Inverter control panels are also employed in battery backup systems, electric vehicles, and energy storage systems.
The DC–AC converters inject sinusoidal current into the grid controlling the power factor. Therefore, the inverter converts the DC power from the PV generator into AC power for grid injection. One important part of the system PV connected to the grid is its control. The control can be divided into two important parts.
In some works, the control of the inverter connected to the grid is based on a DC-link voltage loop cascaded with an inner power loop instead of a current one. In this way, the current injected into the grid is indirectly controlled.
The inverter is decoupled of the grid. The output voltage of the PWM inverter is already set by the utility PV modules. Therefore the inverter is current controlled to ensure only power injection into the grid. The power control is obtained by means of the inverter output voltage shifting phase, PCSP (Power Control Shifting Phase).
In the realm of electrical engineering, inverter control panels stand as pivotal components, orchestrating the seamless flow of power in various industrial applications.
