“…These options are summarized in Table I, which provides levelized cost figures for 2010 [18] and life cycle GHG emission intensity estimates [19]. Although Obara et al [21] study the use of a fuel cell microgrid with tidal power to supply locally produced energy for local consumption in Japan, tidal power is not featured in this analysis because its contribution to the Japanese electricity mix in the near future will likely be insignificant. The table also lists some qualitative factors which are not captured in levelized cost or GHG emission intensity but may either favor or limit the expansion of each technology in Japan.…”

SUMMARY Japan has not settled on a coherent long‐term electricity strategy for its post‐Fukushima reality. In this analysis, a stochastic electricity sector simulation model is formulated and used to evaluate alternative strategies prescribing different generation mixes for 2050. The generation mix evolves deterministically, demand is endogenous, and social cost of carbon is randomly sampled. The model treats fossil fuel prices and advanced technology cost dynamics stochastically. Monte Carlo simulation produces a distribution of net present social cost for each strategy, and the alternatives are assessed based on the median (expected cost) and standard deviation (risk). Aggressively expanding renewables is a promising strategy; it has the lowest expected cost and moderate risk. Whether this is preferred to substantial nuclear generation is sensitive to parameter assumptions, but a general finding is robust: severely limiting nuclear generation and substituting liquefied natural gas (LNG) and other fossil fuels is costly and risky. Principal component analysis confirms the vulnerability of such strategies to LNG price and social cost of carbon uncertainty. Japan's dominant short‐term response to Fukushima has been a dramatic decrease in nuclear generation coupled with increased use of fossil fuels, particularly LNG. This study suggests that continuing this approach would constitute a poor long‐term Japanese electricity strategy. Copyright © 2014 John Wiley & Sons, Ltd.

“…With the velocity and water elevation being predicted, it is convenient to apply these models to assess the tidal energy distribution in real coastal areas . Many studies have been conducted to estimate tidal power production potential without considering the effect of turbines on the flow . In some models, the effect of turbines is included by increasing the drag, which is represented using bed friction.…”

SUMMARYEnergy sustainability has become one of the most concerned issues around the world, and tidal stream power is one of the promising types of renewable energy with merits of high predictability, relatively low cost, and low environmental impact. Numerical models based on the shallow water equations (SWE) have been applied to assess the energy distribution and environmental impact. In existing SWE models, the effect induced by tidal stream turbines on the fluid is usually represented by bed friction, which is only applicable for far-field studies. In the current study, a Blade Element Momentum (BEM) model has been developed and integrated into a three-dimensional (3D) SWE model to improve the accuracy for assessing tidal current energy distributions. Using the BEM approach, state variables can be obtained for a blade element of a turbine rotor. These state variables can be used to calculate the local thrust coefficient, which is introduced for representing the effect of rotors in the 3D SWE models. A 3D SWE model has been refined, by incorporating the proposed BEM model, to simulate the density distribution of a tidal turbine farm. The refined SWE model has been validated against measurements from a flume experiment of turbine arrays. The model performs generally well in predicting the distribution of velocity deficit and the recovery of wakes. In a field-scale application to a planned tidal power test site, the model was used to predicting the flow field for both a single turbine scenario and a turbine array scenario.

The world will need greatly increased energy supply in coming years because of the rapidly increasing world population and depleting natural resources. For a long time, conventional energy sources have been utilized for power generation, but now it is of great concern that the rapid depletion of conventional sources added with their economic and environmental concerns are incompatible to address issues like growing electricity demand and environmental damages. Utilization of the alternative energy sources is compulsory to minimize the energy crisis around the world. Based on the alternative energy sources, a number of power generation systems have been designed to contribute for the management of optimized energy supply systems. The unpredictable nature of alternative energy sources is their common drawback, and they do not harness usable power for some considerable duration of time over the year. Therefore, trends are in progress to integrate two or more than two of these alternative energy systems to meet the required electricity supply in power generation operations. These systems are designated as hybrid systems and can be grid connected or off-grid depending upon their purpose and mode of fabrication. Off grid hybrid systems are popular for the electrification of the isolated and far-flung areas, where the grid supply is absent. This study mainly focuses on main 10 off grid, bi-source hybrid systems for power generation highlighting their role in energy stability. Systems' hybridization, power generation, energy flow schemes, operation schemes, and storage and backup needs have been addressed thoroughly in this study to provide a handy reference to stake holders for further work in this regime.
