“…Similarly, the detailed modeling of power converters is required for assessment of the dynamic behavior of such a grid. In the future, MTDC transmission may help to reduce the number of converters, the capital cost of new installations and switching losses [69][70][71].…”

This paper presents an overview of the DC link development and evolution dedicated to HVDC structure for connecting offshore wind power plants to onshore power systems. The growing demand for the green energy has forced investors in power industry to look for resources further out at sea. Hence, the development of power electronics and industrial engineering has enabled offshore wind farms to be situated further from the shore and in deeper waters. However, their development will require, among other technologies, DC-DC conversion systems. The advantages of HVDC over HVAC technology in relation to transmission distance are given. The different HVDC configurations and topologies of HVDC converters are elucidated. In this context, the HVDC grids are a promising alternative for the expansion of the existing AC grid.

“…Despite AC transmission being the norm for so long, recent advancements in power electronic devices and control systems along with the uptake in renewable energy sources (RES), the trend towards HVDC systems and their coexistence with AC networks is on the rise. More than 180 HVDC projects are reportedly operational across the globe [10].…”

It is expected that superconducting technologies will play an important role in the future smart grid because their application brings a host of benefits, most notably a decrease power loss that allows for overload relief, the lowering of voltage levels, power quality enhancement and subsequent grid stability. The phenomenon of superconductivity brings these potential qualities to the grid in the form of a number of technologies analogous to the commonly accepted, conventional types in the form of cabling, fault current limiters, energy storage (ES), generators and transformers. This paper aims to provide an overview of these technologies and their current and potential applications.

“…There are rich controllable resources in the future distribution systems, such as the distributed photovoltaic (PV), on load tap changing (OLTC) transformer, shunt capacitor and so on. Particularly, new technologies such as DC interlinks between distinct distribution feeders have been introduced to aid the management of distribution systems [3,4]. Therefore, checking the feasibility of a candidate planning solution should rely on analyzing the manipulation control details rather than hardware redundancy alone [5].…”

Better flexibility and controllability have been introduced into distribution system with the development of new loads and resources. As a consequence, the connotations and tools for evaluating the planning solution need to be further enriched. This paper proposes a fast algorithm to quantify steady-state voltages and load profiles in distribution system by simulating the manipulation control process of controllable resources, taking the efficiency and ease of use into account. In this method, a complex distribution system is decoupled into several simple parts according to the ports of the DC interlink. Then, to achieve the qualified voltages and load profiles, the manipulation details of controllable resources are simulated following a certain control sequence in each part. Finally, the analysis results of each part are matched and filtered to obtain a complete evaluation. Five of the most commonly controllable resources are considered in this method. The effectiveness of the proposed method is demonstrated through a case study based on field data from an actual distribution system.
