“…According to [21] this form of control is crucial for ensuring the efficient operation of the MT-HVDC link, since it shows the system's inherent power balance and stability. [11] indicated that the function of the master converter (i.e. slack VSC) is to deliver or absorb any power imbalances in the DC network.…”

“…The ESO therefore solves instances of OPF problems to account for any changes in the system's steady-state operating points (generators' resource dispatch, transformers' tap changer positions, and other controller actions) to plan the system operation in a reliable and economic manner ahead of real-time operation. Yet, developing accurate models that are capable of representing the control actions of VSC converters, especially in the context of operating in a meshed MT-HVDC network is still an area of active research [10,11].…”

This paper presents a comprehensive analysis of a meshed MT-HVDC topology with three wind farms connected to the Substation Ring Topology (SRT) and investigates the steady state performance of the MT-HVDC system based on the VSC control strategies (i.e. conventional method and droop control), which was modelled via the FUBM model and produced results that is useful for solving Optimal Power Flow, particularly in the systems where hybrid AC/DC are adopted to integrate with the large-scale wind resources. The main focus is on the impact evaluation of various VSC control strategies. The outcome indicated that the VSC based MT-HVDC system performs well in terms of power transmission stability and reliability. The operational gain of the simulation results is that the Electricity system operator has the preference for the most robust strategy for the operational planning depending on the system requirements.

“…The determination of droop sparsity is essential for voltage droop control [23], and the smaller of DC droop coefficient is, the greater deviation of power allocation in the side of DC network will be caused by the DC line voltage drop under the condition of neglecting the resistance of the DC line [24, 25]. At the same voltage level, the total loss of the system can be reduced by a reasonable droop coefficient [26]. The flexibility of traditional voltage droop control with fixed coefficient is relatively poor under the complex working conditions.…”

“…In the study [18], a simulation of the integration of the HVDC network shows a reduction in power loss with increasing demand. The optimal power flow of the combined AC and VSC-MTDC system has a growing impact on the transmission grid, as shown in the study [19], to decrease active power losses [20]. Kumar et al [21] proposed the idea of network change to improve the voltage profile and decrease transmission losses in the practical utility transmission network.…”

The transmission network of a power system is important in connecting interactions between the generation and distribution sides. A significant aspect in the power system profile is voltage improvement. This study intends to examine the impact of inserting High Voltage Direct Current (HVDC) on the system's voltage stability, network power losses and power transfer capacity of transmission network under several cases of load contingency. IEEE 57-Bus test system is used for testing the addition of HVDC transmission based on genetic algorithm. Modeling of point-to-point HVDC transmission and multi-terminal HVDC transmission is carried out using the Power System Simulator for Engineering (PSS/E) version 32 Package Program (A collection of computer programs and organized data files called PSS/E software was developed by Siemens PTI to handle the fundamental tasks of power system performance simulation work). The system's performance was compared with and without the HVDC inserted under different loading scenarios: 5%, 10%, and 20% of the total load. The comparative results can show that active power losses at the normal load case are reduced by 55.714% after inserting point to point HVDC topology, and after inserting multi-terminal HVDC topology reduced by 68.214%. Also, the reactive power losses reduce by 55.714% after inserting point to point HVDC topology and after inserting multi-terminal HVDC topology reduced by 66.830% at the same case. The results shown that inserting HVDC Transmission to the system gives better improvement in bus voltage profile and a significant reduction in total network power losses and increase in power transfer capacity of transmission network. The results also showed that multi-terminal HVDC transmission is better in voltage improvement and total power losses reduction when HVDC Transmission is added to the system.
