In this paper, a novel economic analysis for multiterminal voltage‐source converter high‐voltage direct current (MTDC) systems with wind farms is developed. Both the reinforcement and operation methods of an MTDC system are determined hierarchically in the proposed approach. Based on these methods, not only wind power transmission but also the MTDC system is capable of contributing to the power transmission among alternating current (AC) grids in cases of low wind power production cases. As a consequence, the economic benefits produced by the MTDC system can be increased. This paper also focuses on the sensitivity analysis of small‐signal stability constraints on the developed approach. It is demonstrated that the system for wind power transmission without any MTDC systems is exposed to instability, which is solved by the proposed method. On top of that, the small‐signal stability improvement effect of the MTDC system is analyzed from the economic viewpoint. Under strict small‐signal stability constraints, the economic benefits obtained by the MTDC system increase. © 2020 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.

“…radial, ring, multi-terminal, meshed) for the NSOG will be from an operational standpoint. Such studies are often based on pure dynamic simulation techniques (and not optimization) and use different performance indicators, such as evaluation of steady-state losses and fault analyses [29], grid congestions and wind utilization [30], and cost-benefit analysis of different topologies [31]. In [32], an actual optimization is carried out in order to identify the most economical topology, considering both HVAC and HVDC alternatives and optimizing the grid voltage level.…”

Abstract-The goal of this paper is to review, systematize and critically discuss the approaches that have been proposed so far for grid transmission expansion in HVDC systems. In particular, the paper will focus on the special planning requirements of offshore HVDC grids, which have been seldom addressed by available literature. This contribution will first highlight how traditional expansion planning approaches commonly applied to AC systems need to be modified to properly include the HVDC technology; then it will outline how strategies and tools should be adapted when dealing with large offshore HVDC systems, such as the forthcoming North Sea Offshore Grid. On this respect, an updated overview of existing and planned HVDC links in the North Sea will be provided. Finally, a discussion of the specific challenges that need to be properly addressed by the expansion problem of offshore HVDC networks will be presented, with particular emphasis on renewable energy integration and control issues.

“…By assuming project lifetime (t = 30 years), discount rate (4%) 35 , and OPEX [276] (1% of CAPEX) , the LCoT was estimated [276], using Equation (20). No learning assumptions were considered here, as HVAC is regarded as a mature technology [291].…”

Learning, future cost and role of offshore renewable energy technologies in the North Sea energy system

This article reviews experience curve applications in energy technology studies to illustrate best practices in analyzing technological learning. Findings are then applied to evaluate future performance projections of three emerging offshore energy technologies, namely, offshore wind, wave and tidal stream, and biofuel production from seaweed. Key insights from the review are: First, the experience curve approach provides a strong analytical construct to describe and project technology cost developments. However, disaggregating the influences of individual learning mechanisms on observed cost developments demands extensive data requirements, e.g., R&D expenditures, and component-level cost information, which are often not publicly available/readily accessible. Second, in an experience curve analysis, the LR estimate of the technology is highly sensitive to the changes in model specifications and data assumptions. Future studies should evaluate the impact of these variations and inform the uncertainties associated with using the observed learning rates. Third, the review of the literature relevant to offshore energy technology developments revealed that experience curve studies have commonly applied the single-factor experience curve model to derive technology cost projections. This has led to an overview of the role of distinct learning mechanisms (e.g., learning-by-doing, scale effects), and factors (site-specific parameters) influencing their development. To overcome these limitations, we propose a coherent framework based on the findings of this review. The framework disaggregates the technological development process into multiple stages and maps the expected data availability, characteristics, and methodological options to quantify the learning effects. The evaluation of the framework using three offshore energy technologies signals that the data limitations that restrict the process of disaggregating the learning process and identifying cost drivers can be overcome by utilizing detailed bottom-up engineering cost modeling and technology diffusion curves; with experience curve models.
