“…6 as follow to the Eq.

SOFC A basic concept of thermodynamic analysis of energy conversion processes is important when modelling electrochemical processes of fuel cells.Generally the classification of fuel cell can be seen by the type of electrolyte they use, and the choice of electrolyte dictates the range of their operating temperature and the degree of fuel processing required.Solid Oxide Fuel Cells (SOFCs) are high-temperature (600-1000°C) direct energy conversion devices, which transport the chemical energy of a fuel to electrical energy with approximately efficiencies as high as 70% up to 90% in combined heat & power (CHP) generation. There are many auxiliary devices working behind the scene in order to operate smoothly and efficiently.…”

“…Although tidal power generation is one of the renewable energies which has a good predictable output power, due to the rotation of solar, lunar, and earth gravitation. Hence, to get to know the fluctuation responses of tidal power, the analysis should be done at least for one week or one month [6][7][8].…”

“…In recent years, stand-alone microgrid has received much attention, as it is the most appropriate solution to power shortage demand in those remote island and mountain areas [3][4][5]. The basic requirement of a stand-alone microgrid system is to simultaneously achieve a secure, stable, economic, and reliable power supply to satisfy the load demand.…”

-A dynamic economic dispatch and control method is proposed to minimize the overall generating cost for a stand-alone microgrid in DongAo Island, which is integrated with wind turbine generator, solar PV, diesel generator, battery storage, the seawater desalination system and the conventional loads. A new dispatching strategy is presented based on the ranking of component generation costs and two different control modes, in which diesel generator and battery storage alternate to act as the master power source to follow system power fluctuation. The optimal models and GA-based optimization process are given to minimize the overall system generating cost subject to the corresponding constraints and the proposed dispatch strategy. The effectiveness of the proposed method is verified in the stand-alone microgrid in DongAo Island, and the results provide a feasible theoretical and technical basis for optimal energy management and operation control of stand-alone microgrid.

“…After the nuclear disaster of 2011, research activities on independent microgrids for local generation and local consumption, containing sustainable renewable energy generation such as wind, solar and tidal power have increased considerably. Operation of microgrids, aiming at the reduction of CO 2 emissions and the safety of energy supply, in cold, urban and remote areas has been studied [12][13][14].…”

This paper presents an operation strategy for a power system supplied from 100% renewable energy generation in Kitami City, a cold region in Japan. The main goal of this work is the complete elimination of the CO 2 emissions of the city while keeping the power frequency within prescribed limits. Currently, the main energy related issue in Japan is the reduction of CO 2 emissions without depending on nuclear generation. Also, there is a need for the adoption of distributed generation architecture in order to permit local autonomous operation of the system by the local generation of power. As a solution, this paper proposes a strategy to eliminate CO 2 emissions that considers digital simulations using past hourly meteorological data and demand for one year. Results shows that Kitami City can be supplied entirely by renewable generation, reducing its CO 2 emission to zero while keeping the quality of its power grid frequency within permitted limits.
