“…At present, the schedule for placing a fusion power plant on the grid is uncertain despite the numerous long-range plans [64][65][66][67][68] developed to date. Besides the lack of funding and necessary political support, the prime reasons are the unreadiness of almost all necessary technologies, the varying degree of physics extrapolation from ITER to advanced power plants, and the lack of a demonstrated, fully-integrated fusion facility.…”

“…Figure 10 displays a collection of unofficial projections for the tokamak concept of when the Demo and first commercial fusion power plant might be built separately by various nations [69]. The most optimistic projection is by the Koreans with a scenario for the first fusion power plant adding electricity to the grid in the 2040s [68]. The other countries are targeting fusion power production in the 2050s.…”

Fifty years ago, the secrecy surrounding magnetically controlled thermonuclear fusion had been lifted allowing researchers to freely share technical results and discuss the challenges of harnessing fusion power. There were only four magnetic confinement fusion concepts pursued internationally: tokamak, stellarator, pinch, and mirror. Since the early 1970s, numerous fusion designs have been developed for the four original and three new approaches: spherical torus, field-reversed configuration, and spheromak. At present, the tokamak is regarded worldwide as the most viable candidate to demonstrate fusion energy generation. Numerous power plant studies (>50), extensive R&D programs, more than 100 operating experiments, and an impressive international collaboration led to the current wealth of fusion information and understanding. As a result, fusion promises to be a major part of the energy mix in the 21 st century. The fusion roadmaps developed to date take different approaches, depending on the anticipated power plant concept and the degree of extrapolation beyond ITER. Several Demos with differing approaches will be built in the US, EU, Japan, China, Russia, Korea, India, and other countries to cover the wide range of near-term and advanced fusion systems.

“…Preliminary design studies of DEMO reactors have been performed by several groups in a fusion thermal output range of 1500-5000 MW [28][29][30][31][32]. Key elements so far learned from these studies are the dense and stable plasma, the tritium breeding blanket system, scheduled maintenance scenario of the in-vessel components such as blanket modules and diverters keeping a reasonable availability [32,33].…”

An international joint project of fusion experimental reactor, the ITER (International Thermonuclear Experimental Reactor), is reviewed in view of long-range fusion energy research and development (R&D). Its purpose, goal, evolution, and the present construction status are briefly reviewed. While the ITER is a core machine in the present stage, generation of electricity is a role of the next-step fusion demonstration power plant "DEMO." The status of designs and technology R&D for DEMO are also reviewed.

“…For those substations, the voltage values are fixed to the upper or lower limit and in order to keep the voltage to these limits, the storage devices inject or absorb additional current which is indicated by the new terms added in Eq. (6). In this algorithm, since it is assumed that the energy storages have a 95% energy efficiency, a sign and a coefficient are selected differently followed by the storage's operation modes; positive and 1.0 for charging; negative and 0.95 for discharging.…”

“…These efforts can be divided into the development of alternative energy sources and the reduction of energy consumption. A number of studies on renewable, distributed, and nuclear fusion power generation are actively in progress for alternative energy sources which do not use fossil fuel and are not sources of CO 2 emissions [1][2][3][4][5][6]. Efforts on the reduction of energy consumption deal mainly in the process of how to improve energy efficiency.…”

-There is an increasing interest in research to help overcome the energy crisis that has been focused on energy storage applications in various parts of power systems. Energy storage systems are good at enhancing the reliability or improving the efficiency of a power system by creating a time gap between the generation and the consumption of power. As a contribution to the various applications of storage devices, this paper describes a novel algorithm that determines the power and storage capacity of selected energy storage devices in order to improve upon railroad system efficiency. The algorithm is also demonstrated by means of simulation studies for the Korean railroad lines now in service. A part of this novel algorithm includes the DC railroad powerflow algorithm that considers the mobility of railroad vehicles, which is necessary because the electric railroad system has a distinct distribution system where the location and power of vehicles are not fixed values. In order to derive a more accurate powerflow result, this algorithm has been designed to consider the rail voltage as well as the feeder voltage for calculating the vehicle voltage. By applying the resultant control scheme, the charging or discharging within a specific voltage boundary, energy savings and a substation voltage stabilization using storage devices are achieved at the same time.
