Abstract As a clean and efficient power generation device, molten carbonate fuel cell(MCFC)can directly convert chemical energy into electrical energy at the operating temperature of 650 degrees, avoiding the heat loss caused by the Carnot cycle, and effectively reducing the emission of CO2 and other pollutants. This paper introduces the background, basic principle, system design and current situation of fused carbonate fuel cell at home and abroad, and explains the technical problems that molten carbonate power generation technology is facing. At the same time, the cost of the molten carbonate power generation system is analyzed, and the present cost and the cost after industrialization are compared and evaluated to provide a reference for the economy of the molten carbonate fuel cell power generation system.

Solar energy is an inexhaustible source of clean energy. Meanwhile, supercritical carbon dioxide has excellent characteristics such as easy access to critical conditions, high density, and low viscosity, making it one of the most popular circulating working fluids in solar power generation technology. However, solar power generation systems are severely affected by geographical distribution, seasonal variations and day-night cycles. Therefore, efficient and adaptable turbine design is the key to realize supercritical carbon dioxide solar power generation technology. In this paper, the initial thermodynamic design of 10 MW S-CO2 three-stage axial turbine is completed by self-developed thermodynamic design software, and the key thermodynamic and structural parameters are obtained. The optimal design of turbine and its aerodynamic performance at rated operating conditions are obtained by using a three-dimensional aerodynamic numerical analysis and optimization method. At last, nine off-design conditions are analyzed in detail. The results show that the designed turbine output power is 10.37 MW and the total-total efficiency is 91.60%. It can operate efficiently and steadily in the range of output power from 16.2% to 155.9%. It can adapt to the variable operating conditions of solar power generation system and meet the design requirements.

World climate change challenges and the world’s consistent growing demand for energy during the past decade have brought the need to explore for more renewable energy resources. The continuation of exploring green energy sources results Osmotic Power- a new emission-free source of sustainable energy that can be used to generate electricity. Osmotic power plant is only feasible in places where rivers flow out to the ocean. The leading virtue of osmotic power is that it would be capable to produce a steady and reliable supply of renewable base load power as an alternative of other variable sources like solar or wind. There are some hurdles to generate osmotic power. Developing suitable membrane and initial construction cost are top on of them. Though Osmotic power is years from commercial feasibility but researchers think that it could provide thousands of terawatts of base load power per year around the globe. This paper presents an overview of osmotic power generation system with the analysis of potential benefits and limitations of it.

Telecommunications industry requires efficient, reliable and cost-effective hybrid power system as alternative to the power supplied by diesel generator. This paper proposed an operational control algorithm that will be used to control and supervise the operations of PV/Wind-Diesel hybrid power generation system for GSM base station sites. The control algorithm was developed in such a way that it coordinates when power should be generated by renewable energy (PV panels and Wind turbine) and when it should be generated by diesel generator and is intended to maximize the use of renewable system while limiting the use of diesel generator. Diesel generator is allocated only when the demand cannot be met by the renewable energy sources including battery bank. The developed algorithm was used to study the operations of the hybrid PV/Wind-Diesel energy system. The control simulation shows that the developed algorithm reduces the operational hours of the diesel generator thereby reducing the running cost of the hybrid energy system as well as the pollutant emissions. With the data collected from the site, a detailed economic and environmental analysis was carried out using micro power optimization software homer. The study evaluates savings associated with conversion of the diesel powered system to a PV/Wind-Diesel hybrid power system.

Due to the lack of fossil fuels, people are paying more and more attention to renewable energy. Wind energy is one of the important renewable energy. Unpredictability and volatility of the wind source make the output power unstable, so we need to control the active Power. This paper uses fuzzy control method, and the simulation results show that fuzzy control method mentioned in this paper is better than the conventional PI control for Wind power, the nonlinear system. Based on the analysis of pitch control theory and control process, we design fuzzy pitch controller and its model. We simulates gust wind speed imitates, wind turbine control and verifies the effects of the blur pitch control in a constant speed and constant frequency wind power generation system. According to the results of the simulation, we know the pitch controller of fuzzy logic has a better effect on the active control of the generator of the wind power generation system.

Abstract As industrialization, worldwide population growth, and improvements in the living standards in developing countries continue, demands for energy, food, and water, likewise surge. This in turn accelerates global warming, and its resultant extreme weather effects. Among the measures proposed to meet the growing energy demands, the use of renewable energy is gaining more and more attention. In particular, wave power generation is attracting a great deal of attention as an effective use of ocean energy. However, current wave generators are large and very expensive relative to their output. Furthermore, they cannot generate power efficiently with wave directivity, small amplitude waves and so on. For these reasons, widespread use is very limited. In order to solve these problems, this paper discusses the possibility of a recently developed wave power generator that uses a newly developed dielectric elastomer (DE) as a new way to harvest renewable energy. We also discuss the technical breakthrough of building a mega power generation system using DEs.
