Active and Reactive Power Control of Grid Connected Distributed Generation Systems

Experimental validation of a single phase intelligent power router

“…The principle of operation is set so that power is equal at both sides. The AC side is modeled as a voltage source while DC side is seen as a current source [18]. This procedure simplifies the control part because there are not harmonic distortions and commutation losses are neither taken into account.…”

Operation and control of a Current Source Converter series tapping of an LCC-HVDC link for integration of Offshore Wind Power Plants

“…The control scheme includes one current loop to regulate q and d components of the stator current. The obtained controllers are two PI designed using IMC methodology [31] in order to achieve a first order response. The control scheme is depicted in Fig.…”

“…The grid side converter uses the classical vector control with two cascaded control loops [31]: The inner loop controls current qd components independently while the outer loop regulates the DC voltage. Reactive power is kept to 0, controlling i bd to 0.…”

“…Reactive power is kept to 0, controlling i bd to 0. The PI controllers are also tuned with IMC technique [31]. The Dynamic Breaking Resistor (DBR) is in charge of keeping the DC voltage below its maximum value.…”

Robust Repetitive Current Control of Two-Level Utility-Connected Converter using LCL Filter

“…The novel structures of these converters, e.g., multiphase modular converters (M 2 LC), have been further developed and are being used by industry. Modular architecture can provide high reliability and easy maintenance in addition to bidirectional power flow at all ports with active and reactive control [9]. These converters have the advantage of reducing the voltage step changes at the expense of increased complexity, cost of the power electronics, and control components.…”
