“…Moreover, the operation of the power converters must be controlled with the aim to regulate any desired electrical variable of the system. In the literature, several strategies have been proposed to address the control of power systems containing renewable energy sources [6][7][8][9][10][11][12].…”

“…The aim was to simultaneously Electronics 2021, 10, 1061 2 of 19 perform both power-fluctuation mitigation and damping improvement of four paralleloperated offshore wind farms delivering generated power to a large utility grid. In [8], an active power control strategy for a VSC-HVDC-linked islanded wind farm was proposed. The strategy is based on standard vector control to regulate the output currents.…”

The development of distributed generation, mainly based on renewable energies, requires the design of control strategies to allow the regulation of electrical variables, such as power, voltage (V), and frequency (f), and the coordination of multiple generation units in microgrids or islanded systems. This paper presents a strategy to control the active and reactive power flow in the Point of Common Connection (PCC) of a renewable generation system operating in islanded mode. Voltage Source Converters (VSCs) are connected between individual generation units and the PCC to control the voltage and frequency. The voltage and frequency reference values are obtained from the P–V and Q–f droop characteristics curves, where P and Q are the active and reactive power supplied to the load, respectively. Proportional–Integral (PI) controllers process the voltage and frequency errors and set the reference currents (in the dq frame) to be imposed by each VSC. Simulation results considering high-power solar and wind generation systems are presented to validate the proposed control strategy.

“…There are various control strategies for controlling the VSC-HVDC system that has been proposed in published literature. A control strategy in [4] is based on controlling the active power using the phase angle between the fundamental component of the output voltage of the VSC-based HVDC system and the grid voltage. While the reactive power is controlled by using an auxiliary measure.…”

Recently, the offshore wind farms (OWFs) have excellent potential in global power networks. So, the demand for high power and high‐quality transmission system is becoming more pressing with the fast growth of OWFs. A promising solution is provided by the voltage source converter‐high voltage direct current (VSC‐HVDC) system. This paper proposes a control method for controlling the VSC‐HVDC system to integrate OWFs into power grids based on model predictive control (MPC). To minimise the distortion and filtering of the harmonics injected into the utility grid, the receiving end converter of the VSC‐HVDC system is connected with LCL filter. The proposed control strategy maintains active/reactive power‐sharing with efficient regulation of AC voltage among the different OWFs operation conditions. The detailed system components modelling and simulation are executed in the MATLAB/Simulink environment, which is used to perform both dynamics and transient evaluation of the suggested control strategy. The acquired simulation results emphasize the capability of the proposed control strategy to maintain system stability under different operation conditions compared to the synchronous reference frame‐based current limiting droop control method (SRF‐based CLD).

“…High voltage direct current (HVDC) transmission has been proved as the only viable and most economical choice for bulk-power delivery over long distances [1]. On the other hand, rising voltage and current levels increase the converter electrical stress value and cause some disadvantages, such as overvoltage, insulation coordination and electromagnetic compatibility.…”

In this study, the modelling methods are compared in terms of their accuracy and modelling simplicity for different types of components. And the principle of the equivalent circuit model is obtained from reference and is used in the proposed equivalent circuit models of other equipment of HVDC converter stations. Then, all the models are connected into an HVDC system, and simulations are conducted to verify the validity of the proposed model. A comparison with the traditional modelling method shows that the proposed method is more effective for studying entire HVDC converter stations, and is also better suited for equipment building and simulating. Simulation results show that the model is effective and acceptable.
