Malaysia nowadays depends heavily on conventional energy resource for generating electricity and transportation. This will give negative impact and trigger other problems if not well managed. Therefore, it is very important to increase the use of renewable energy especially the tidal energy as the tidal energy is more predictable and reliable renewable energy source. A kinetic energy produced by the tidal differences will be used to generate electricity and involves the use of a tidal turbine. There are two approaches that are being used to harness the tidal energy for the generation of electricity which are barrage approach and tidal stream approach. This paper identify the potential region along west coast of peninsular Malaysia that has higher potential power generation for harnessing tidal energy and study which approach suitable to be applied. From the results, show that the highest potential power generation for harnessing tidal energy is at Pelabuhan Klang with the average power availability is 591.19kW while the lowest is at Tanjung Keling with the average potential power generation is 52.75kW.

Tidal Power Generation

The global economic and social developments depend largely on fossil fuels nowadays. To cope with energy crisis and environment problems caused by consumption of fossil fuels, the renewable energy exploitation is an alternative path. As one kind of renewable ocean energy which can be applied into production, tidal energy is mainly utilized in electricity generation. China has abundant tidal energy resource, which mainly distribute in the southeast coastal areas where power supply is insufficient. China's tidal power generation started in 1958, and some experience and technologies have been accumulated from the long-time history of tidal power station construction and operation. At present, China’s tidal energy’s development and utilization are still in low level, and remain plagued by several challenges, such as high cost, and insufficiency of preferential policies and regulations. While, China's tidal power generation must be very promising in the foreseeable future, with a great deal of attention paid to the utilization of renewable energy and the perception of sustainable development.

Currently, renewable energy can only support 5% of national energy needs. Meanwhile, in 2035 renewable energy targeted to sustain 14% of total national energy demand. The proper way for optimizing the renewable energy is needed to actualize the target. Tidal energy as one of the potentials that are still being developed and need more attention from the government. Tidal can be used for natural energy resource since it has zero emission, produce big energy, and has no impact to weather. Larantuka Strait located in Flores island, Nusa Tenggara Timur province can produce tidal velocity up to 2.859 m/s with water density as much as 1.025 gr/cc.  In utilizing this energy, we use new innovation by using dual tidal turbines which placed at the foot of Palmerah Bridge. The construction of Palmerah Bridge is built both by the government of Flores Island and Adonara Island. Dual tidal turbines are more efficient than singl e turbine by reason of tidal that has passed through the first turbine can be used again for the second turbine. The using of the generator is meant to convert kinetic energy that produced by dual tidal turbines. To convert ocean currents into electrical energy optimally, it is necessary to plan turbine designs that are in accordance with the conditions of ocean currents and the surrounding environment such as current velocity, wind influences and so on. Horizontal-axis tidal turbine (HATTs) is one of the technologies that are being developed and tested in prototype form by several companies, an efficient blade design is very important for the success of the HATTs. The amount of turbine needs, in this case, is 15 turbines with each turbine’s length is 10 meters. The turbines installed in bridge’s column along 800 meters. Estimate electricity can be generated by the turbine is 1.48 Mega Watt (MW).

This paper addressed assessing feasibility of hybrid use of ocean renewable energy, such as wave and wind energy around Japanese coast. At first, wave and wind energy theoretical potentials were calculated and, in the second step, correlation coefficient between wave and wind energy was computed around Japanese coast. Sea area suitable for hybrid use of ocean renewable energy resources is supposed to have high potential for some types of energy resources. Furthermore, correlation of power generation between wave and wind energy resources should be low because one energy resource needs to complement another one for stabilizing power generation. Based on the assumptions, feasibility of wind and wave energy was evaluated on some sea areas where R&D project are ongoing.

Wave Energy Spectrum

We consider the influence of wave-current interactions (WCI) on the tidal energy resource through changes in the velocity field of tidal currents. In order to investigate this, we have run three models: SWAN (stand-alone), ROMS (stand-alone) and COAWST (two-way coupled ROMS and SWAN model). The research area of our studies is Alderney Race, France, an area with strong currents, which has a strong potential for tidal turbine deployment. The time period used for the simulations was March 2008, when a strong storm hit the Alderney Race area and produced significant wave heights (Hs) of up to 7 m and a Stokes drift near the surface close to 0.3 m/s. Furthermore, in order to see the extent of the influence of large waves on current parameters, two virtual storms with larger waves have been generated by magnifying the wave energy spectrum and changing the frequency of the spectrum of the real storm in March 2008. The 3D and the barotropic velocity field were analysed in order to see if the WCI in the waters of Alderney Race during storm conditions can cause a significant increase or decrease of the current speed and through which mechanisms. This study also investigates the Turbulent Kinetic Energy (TKE) in order to portray the turbulent conditions in the area of interest which are important for resource characterisation and device design.

Tidal Turbine

This Round Robin Test program aims to establish the influence of the combined wave and current effect on the power capture and performance of a generic tidal turbine prototype. Three facilities offering similar range of experimental conditions have been selected on the basis that their dimensions along with the rotor diameter of the turbine translate into low blockage ratio conditions. The performance of the turbine shows differences between the facilities up to 25% in terms of average power coefficient, depending on the wave and current cases. To prevent the flow velocity increasing these differences, the turbine performance coefficients have been systematically normalized using a time-average disc-integrated velocity, accounting for vertical gradients over the turbine swept area. Differences linked to blockage effects and turbulence characteristics between facilities are both responsible for 5 to 10% of the power coefficient gaps. The intrinsic differences between the tanks play a significant role as well. A first attempt is given to show how the wave-current interaction effects can be responsible for differences in the turbine performance. In these tanks, the simultaneous generation of wave and current is a key part often producing disruptions in both of these flow characteristics.

Photovoltaic Power

In recent years, with the gradual depletion of traditional energy, as renewable energy representatives, new energy has developed rapidly. We know that distributed photovoltaic power generation with clean, pollution-free, easy installation, and therefore has been rapid development. However, the large number of distributed photovoltaic power generation connected to the distribution network would have a negative impact on the grid with a safe and reliable operation because of its randomness and volatility intrinsic properties. In this paper, in terms of power flow, voltage distribution, load characteristics, power quality, system protection and reliability departure, through MATLAB simulation analysis, the distribution network transformation strategies of primary and secondary devices has been proposed. It laid an important foundation for renewable energy development and the Third Industrial Revolution.

Offshore renewable energy has been showing remarkable growth and acceptable yields over recent years, the concept of this study centres on the idea of connecting a wind turbine to a tidal turbine, where both energy sources may be utilised at any one location for maximum energy yield. AutoCAD and MATHCAD have been used to simulate the aerodynamics and hydrodynamics of the structure. The power generation and risk analysis were also accounted for. The result of a wave spectral analysis effect on tidal turbines is demonstrated in the study for 6 different cases at different mean crossing period, wave heights, and fatigue life. The power generation of 2 bladed wind/tidal turbine versus 3 bladed was calculated. Although 3 bladed turbines have a marginal higher power generation output, this does not reflect the feasibility of the extra percentages of power on the economics.

The Moment

Malaysia is one of the fastest emerging and developing countries in the world. To drive the economical workhorse, large amounts of power is required. The power demand has risen to 156,003 GWh per year in the year 2016, almost 30,000 GWh more than 5 years prior. Fossil fuels such as natural gas, coal, oil, and diesel have been the driving force powering Malaysia’s grids. However, these resources will not last forever, and they do harm to our environment. To counter this, renewable energy (RE) projects have been constructed all around Malaysia. This paper discusses on available and existing renewable energy systems (single/hybrid) in Malaysia and provides a comparison of their electricity generation capabilities. The renewable energy sources that are covered in this paper include Solar, Hydropower, Biomass, Tidal and Geothermal. At the moment, hydropower is the largest renewable energy producer, contributing to almost 15% of the country’s total energy generation. A lot of resources have been channeled towards the initiative of hydropower and it has definitely borne much fruit. This is followed by Solar Energy. Even though it is not as successful as hydropower, there is still a lot of avenues for it to grow in a tropical country like this. Malaysia is still relatively new in terms of power generation using biomass sources. There has been a gradual increase in the power generation using biofuels through the years and its future does look bright. Energy generation from wind, tidal, and geothermal sources has been rather challenging. Because of Malaysia’s geographical location, it experiences slow winds on average throughout the year. This has led to insufficient output for its financial input. Besides that, Malaysia also has relatively low tide, if compared to other Asian countries such as Indonesia and the Philippines. This contributed to the failure of tidal energy in Malaysia, but there have been signs of locations that can be suitable for this energy generation. Besides that, the country’s first geothermal power plant project failed due to a lack of preparation and discipline during the project’s execution. There is a high initial cost for geothermal projects, and the chances of failure are high if the necessary precautions are not followed. This could be one of the reasons why this branch of renewable energy has not been explored deeply.
