Korea is a very well-known country for having abundant tidal current energy resources. There are many attractive coastal areas for the tidal current power that have very strong currents due to the high tidal range and the acceleration through the narrow channels between islands in the west and south coasts of the Korean peninsula. Recently, the Korean government announced a plan that aims to increase the portion of electricity generated from renewable energy to 20% by 2030. Korea has abundant tidal current energy resources; however, as reliable resource assessment results of tidal current energy are not sufficient, the portion of tidal current power is very small in the plan. Therefore, a reliable resource assessment should be conducted in order to provide a basis for the development plan. This paper describes the resource assessment of tidal current energy in Korea based on the observational data provided by KHOA (Korean Hydrographic and Oceanographic Agency) and numerical simulation of water circulation. As the observational data were unable to present the detailed distribution of the complicated tidal current between islands, numerical simulation of water circulation was used to describe the detailed distribution of tidal current in Incheon-Gyeonggi and Jeollanam-do, where the tidal energy potentials are abundant. The west and south coastal areas of Korea were divided into seven regions according to the administrative district, and the theoretical tidal current potential was calculated using average power intercepted. The results of this research can provide the insight of the tidal current energy development plan in Korea.

Tidal current energy is regarded as one of the most promising alternative energy resources for its minimal environmental footprint and high-energy density. The device used to harness tidal current energy is the tidal current turbine, which shares similar working principle with wind turbines. The high load factors resulting from the fluid properties and the predictable resource characteristics make marine currents particularly attractive for power generation. There is a paucity of information regarding various key aspects of system design encountered in this relatively new area of research. Not much work has been done to determine the characteristics of turbines running in water for kinetic energy conversion even though relevant work has been carried out on ship’s propellers, wind turbines and on hydro turbines. None of these three well established areas of technology completely overlap with this new field so that gaps remain in the state of knowledge. A tidal current turbine rated at 1–3 m/s in water can result in four times as much energy per year/m2 of rotor swept area as similarly rated power wind turbine. Areas with high marine current flows commonly occur in narrow straits, between islands, and around. There are many sites worldwide with current velocities around 2.5 m/s, such as near the UK, Italy, the Philippines, and Japan. In the United States, the Florida Current and the Gulf Stream are reasonably swift and continuous currents moving close to shore in areas where there is a demand for power. In this study tidal current turbines are designed for several high tidal current areas around USA for a tidal current speed range from 1 m/s to 2.5 m/s. Several locations around USA are considered, e.g. the Gulf Stream; Mississippi River, St. Clair’s river connecting Lake Huron to Lake St. Clair’s; Colorado River within Cataract Canyon etc. Tidal current turbines can be classified as either horizontal or vertical axis turbines. In this study several designs from both the classifications are considered and modeled using SolidWorks. Hydrodynamic analysis is performed using SolidWorks Flow simulation software, and then optimization of the designs is performed based on maximizing the starting rotational torque and ultimate power generation capacity. From flow simulations, forces on the tidal current turbine blades and structures are calculated, and used in subsequent stress analysis using SolidWorks Simulation software to confirm structural integrity. The comparative results from this study will help in the systematic optimization of the tidal current turbine designs at various locations.

Considering the depletion of oil, coal, gas and other fossil energy, and the increasingly serious environmental pollution, all countries in the world are developing clean and renewable energy, such as wind energy, water energy, solar energy, etc., to alleviate the current energy crisis. Tidal current energy belongs to the marine renewable energy. It is clean, pollution-free, and abundant, with a good prospect of development due to its similarity with wind energy. This paper firstly analyses the reserves and distribution of tidal current energy in China. Then the early exploration of Tidal Current Power Generation System (TCPGS) in China is briefly introduced. Subsequently, it gives the details of the devices and experimental platforms of TCPGS that were researched and developed by various universities, research institutes and enterprises in China. The information mainly includes: the size and the capacity of the system, the support structure, turbine type, the selection of generator, and some river and offshore test information, etc. Finally, it discusses the similarities and differences between China and other countries in tidal current power generation technology, and summaries the current development status and gives the prospect of the TCPGS technology in China.

Tidal Power Generation

Tidal energy is a kind of new energy which is both renewable and pollution-free so that the tidal power generation is increasingly popular in the world. This paper is with respect to the current situation and prospects of development to the tidal power generation at home and abroad, from which it is realized that countries around the world set out the exploitation and utilization of tidal power generation as early as last century by carrying out a great quantity of research and practice, and building numerous tidal power generation stations. As we all know, water turbine generating units are absolutely necessary for tidal power generation. So this paper also refers to the water turbine generating units used in some tidal power generation stations and briefly presents their characteristics as well.
