Special Issue "HVDC for Grid Services in Electric Power Systems"
Deadline for manuscript submissions: 31 December 2018
We are inviting submissions of original research to a Special Issue of Applied Sciences on the subject of “HVDC for Grid Services in Electric Power Systems”.
The modern electric power system has evolved into a huge nonlinear complex system, due to the interconnection of thousands of generation and transmission systems. The unparalleled growth of renewable energy resources (RES) has caused significant concern regarding grid stability and power quality, and it is essential to find ways to control such a massive system for effective operation. The controllability of HVDC and FACTs devices allows for improvement of the dynamic behavior of grids and their flexibility. Research is being carried out at both the system and component levels of modelling, control, and stability. This Special Issue aims to present novel topologies or operation strategies to prevent abnormal grid conditions.

Title: DC Fault Interruption Performance of Half-Bridge and Full-Bridge MMC based HVDC Systems according to the Fault Location
Abstract: With the continuous improvement in modular voltage source converters (VSC) based HVDC technologies, the interest in the realization of high voltage direct current (HVDC) grids is significantly increasing. The modular multilevel converters (MMC) are based on either half bridge (HB) or full bridge (FB) submodules. These two MMC technologies show significantly different dc fault handling capabilities. The different characteristics directly affect the protection requirement of the HVDC grid. Due to reverse blocking capability of full bridge MMC, circuit breaker is not required as opposed to half bridge based MMC converters which are unable to control the fault current. In this study we have focused on comparison of peak fault current magnitude, fault current interruption duration and energy dissipation during fault in the two types of MMC-HVDC grids depending on the dc fault location. The results confirm that the HB submodule MMC scheme along with HCB has remarkably better fault interruption characteristics compared to Full Bridge MMC.

Title: The Frequency-Power Droop Coefficients Scheduling Method of Mixed LCC and VSC Multi-Infeed HVDC System for Loss Minimization of Islanded network
Abstract: Among the grid service applications of high-voltage direct-current (HVDC) system, frequency-power droop control for islanded network is widely used scheme. In this paper, a new frequency droop coefficients determination method for mixed line-commutated converter-based (LCC) and voltage-sourced converter-based (VSC) multi-infeed HVDC system is presented. The proposed method is designed for minimization of power loss which is caused by load imbalance. An interior-point method is used as optimization algorithm to implement the proposed scheduling method. Two test systems, modified IEEE 14-buses system and the Jeju island network in the South Korea, are utilized for MATLAB simulation case studies to suggest that the proposed method is effective to reduce power system loss during frequency control. Additionally, to demonstrate the steady-state model of LCC HVDC in terms of reactive power characteristic, simulation case study using PSCAD, which is electro-magnetic transient (EMT) based program, is performed.
