Abstract Capturing the tidal energy is one of the ways of tapping natural and renewable energy which do not involve the cost of working fluid/ fuel. The present work focuses on some of the feasibility aspects of setting up of major tidal power plants along the seacoast. Besides, the present study synergizes on methods of estimating the power-producing capacities in regions along the seacoast. Estimation of power-producing capacities, calendar month-wise, and lunar month-wise gave handy information. Also, the estimation of power-producing capacities of different regions along a location gave clarity on the probable regions of interest for producing power simultaneously. A comparison of the estimates with the details of the literature authenticated the study. A discussion of producing more tidal power in specific locations gave insights into the aspects that may have been ignored in the literature. Geographic restrictions along the local seacoast like identifying the security-sensitive regions rationalized the estimating procedures. The paper includes a discussion of various factors that address the feasibility concerns. The study supposedly helps space exploration too.

Module Performance

The use of renewable energy as a source of electrical energyincreases every year. Unfortunately, Indonesia does not have manypower plants that utilize renewable energy sources. The mostpotential renewable energy in Indonesia is the sunlight with the helpof solar panels that converts solar energy into electrical energy.However, the environment could affect the solar panel module andin turn, affect the performance of solar panels or the generatedelectric energy. This research calculated the performance of solarpanels with a single-diode model using the Five Parameters methodthat required solar panel module specification data, the totalradiation absorbed by the solar panel module, and the temperatureof the environment. The Five Parameters method is a methodmodeled after solar panel module performance in the form of thesingle-diode equivalent circuit. The Five Parameters method isreliable in predicting the energy produced by the solar panels whenthe input data is limited. The results for using the Five Parametersin monocrystalline solar panels were Isc = 1.827 A, Imp = 0.662 A,Voc = 18.221 V, Vmp = 15.019 V, Pmp = 9.955 W. And the results inpolycrystalline solar panels were Isc = 1.926 A, Imp = 0.686 A, Voc =17.594 V, Vmp = 14.166 V, Pmp = 9.722 W. Based on the results; itwas concluded that the most efficient and optimised types of solarpanels on natural conditions in Sendang Biru Beach was themonocrystalline solar panel because it produced electrical outputpower of 9.955 W. Therefore, there could be a manufacturer ofsolar energy power plants to reduce the cost of electricity in thecoastal area, such as in Sendang Biru Beach.

Abstract The use of energy, especially electrical power, is needed by the wider community— lots of alternative energy from nature, especially in Indonesia that can be utilized to produce electricity. One of the newest alternative examples is the energy produced by tides. Tidal energy is a type of renewable energy that is relatively more predictable in number. One method that can process the waves is the Least Square Method. Where the results of data processing using this method can be known based on tidal observations for 15 days on Toaya Beach located in Donggala Regency, Central Sulawesi, the types of tidal types that occur based on the results of Formzahl’s count is 0.357 that the tidal types that occur are varied types leaning to double daily, with a Root Mean Square Error (RMSE) of 0.028, which means that the difference between predictive results and observational data is accurate. Then also obtained the value of the design water level elevation that is the highest high water level (HHWL) is 2.7 meters, and the lowest low water level (LLWL) is -0.3 meters with a height difference is 3.0 meters. So with the high height difference, the total energy generated by two times a day with a sea area of 9 km2 which is capable of producing energy movement from seawater can be calculated the potential energy generated from the waves of Toaya Beach, which is 5,53 MW.

The Moment

The relevance of the development of tidal hydropower is extremely high. Tidal energy is the only guaranteed energy on our planet during the entire period of use since it is guaranteed by cosmic forces unchangeable in the foreseeable future. To optimize power generation, TPP turbines should be used in several modes, the choice of which depends on the power required at the moment, the needs and capabilities of other power producers. If TPPs and NPPs need oil, gas, coal, uranium; for hydroelectric power plants – river water (and now there is a shallow period); for wave, wind and solar power plants – sun and wind are needed (today they are available, tomorrow –no); then for a TPP in any range of the World Ocean, the generation of electricity depends only on the attraction of the Moon and the amount of energy received can be accurately determined for any period of time for the entire period of operation, therefore, the TPP can be controlled at a distance of hundreds of kilometers (example of TPP Rane) having only security at the station. The successful implementation of the Severnaya TPP project and its innovative components would be the last stage on the way to industrial development of tidal energy in Russia. The final criterion for the commercial success of a TPP is the cost per 1 kWh of electricity generated by it. Severnaya TPP is designed to supply electricity to remote areas and is therefore economically profitable.

This research focuses on proposing and evaluating an optimized hybrid system of wind and tidal turbines operating as a renewable energy generating unit in New Zealand. Literature review indicates increasing worldwide investment in offshore renewable energy in recent years. Offshore energy shows a high potential as an alternative energy generation solution to that of fossil fuels. Using the capacities of wind and tidal power in renewable technologies would be a suitable alternative for fossil fuels and would help prevent their detrimental effects on the environment. It is a cost-effective procedure for the power generation sector to maximize these renewables as a hybrid system. At the design phase, turbine types appropriate to environmental conditions for an area with high wind speed and tidal flow need to be considered. When selecting which turbines should be used, horizontal or vertical axis, number and length of blades, and optimized rotational speed are all important to get maximum capacity from either the wind or tidal energy for the hybrid system. Comprehensive simulation models of the hybrid system are now being set up, using several available commercial software packages such as QBlade, Simulink, and RETScreen. Several different parameters will be required for these simulation models to run in order to test performance, capacity and efficiency of the proposed hybrid system. To decide which regions are suitable for the hybrid system, it will be necessary to analyze available wind and tide records from NIWA, and online databases such as GLOBAL ATLAS. This next phase of research will aim to create optimized scenarios for the hybrid model by considering the effect of wind and water speed on performance. After deciding which region and scenarios are suitable, it will also be necessary to evaluate the costs and returns of a hybrid system. This final phase will be performed using the RETScreen simulation model.

The Cost

Improving the efficiency of thermodynamic cycles plays a fundamental role in reducing the cost of solar power plants. These plants work normally with Rankine cycles which present some disadvantages due to the thermodynamic behavior of steam at low pressures. These disadvantages can be reduced by introducing alternatives such as combined cycles which combine the best features of each cycle. In this paper a combined Rankine-Goswami cycle (RGC) is proposed and a thermodynamic analysis is conducted. The Goswami cycle, used as a bottoming cycle, uses ammonia-water mixture as the working fluid and produces power and refrigeration while power is the primary goal. This bottoming cycle, reduces the energy losses in the traditional condenser and eliminates the high specific volume and poor vapor quality presented in the last stages of the lower pressure turbine in the Rankine cycle. In addition, the use of absorption condensation in the Goswami cycle, for regeneration of the strong solution, allows operating the low pressure side of the cycle above atmospheric pressure which eliminates the need for maintaining a vacuum pressure in the condenser. The performance of the proposed combined Rankine-Goswami cycle, under full load, was investigated for applications in parabolic trough solar thermal plants for a range from 40 to 50 MW sizes. A sensitivity analysis to study the effect of the ammonia concentration, condenser pressure and rectifier concentration on the cycle efficiency, network and cooling was performed. The results indicate that the proposed RGC provide a difference in net power output between 15.7 and 42.3% for condenser pressures between 1 to 9 bars. The maximum effective first law and exergy efficiencies for an ammonia mass fraction of 0.5 are calculated as 36.7% and 24.7% respectively for the base case (no superheater or rectifier process).

The study presents a brief description and problems of power supply of the Khabarovsk territory. The problems and prospects of the development of renewable energy sources, in particular in the Khabarovsk territory, are considered. There are three main approaches that exist in the scientific community for comparing energy objects. The first approach is based on comparing the technical indicators of power facilities, the second on calculating the normalized cost of electricity, and the third is based on monetizing the environmental and climatic consequences of power facilities. During the study, it was found that these approaches differ in the number of indicators included in the calculation of the cost of electricity. In accordance with the selected approaches, evaluation of economic efficiency of three operating power plants of the Khabarovsk territory – coal, diesel and solar – was carried out, monetized estimates of the full cost of three alternatives for the production of electricity in the region were given, taking into account the environmental component. The analysis made it possible to conclude that under the current market conditions, renewable energy sources are most profitable in decentralized areas, and quantitative evaluations have shown that with the introduction of payments for carbon monoxide emissions, renewable energy sources become an economically effective way of organizing energy supply in the region, including in the regions with centralized power supply.

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.
