“…During this time the natural gas generator is used to meet the load demand and charge the batteries for the amount that the PV array is not able to, and during the summer months when solar energy is more prevalent the generator will be used less, which will in turn extend the life of the generator. The dispatch strategy for this type of arrangement was discussed in detail elsewhere [79][80][81][82][83][84].…”

“…Tables (4) to (5) summarize in detail the results of optimum sizing for different hybrid systems: PV/WT/diesel/battery, PV/diesel/battery, WT/diesel/battery, and diesel generator alone, for first scenario and second scenario respectively. The first scenario (subsidize fuel price, Table 4) the optimum number of PV panels, WTs and batteries in the PV/WT/diesel/battery, PV/diesel/battery, and WT/diesel/battery, are equal to zero, it is clear that economically the diesel generators system is a better choice for providing power.…”

Diesel power technology has been utilized worldwide, especially in remote regions, because of its low initial capital cost. But it has negative effects on the surrounding environment and causes global warming. Also the power supply of off-grid remote area and applications at minimal cost and with low emissions is an important issue when discussing future energy concepts. In Iran, the cost of fuel is highly subsidized. If Iran removes the fuel subsidy, the cost of diesel fuel would increase and the renewable energy systems would become more attractive. This paper presents techno-economic analysis, modeling and optimization of a photovoltaic (PV)/wind/diesel/batterybased hybrid system for electrification to an off-grid remote area located in Rafsanjan, Iran, for different diesel generator fuel price scenarios. For this location, different hybrid (PV/wind/diesel/battery) systems are studied and compared in terms of cost and pollution for two scenarios. For cost analysis, a mathematical model is introduced for each system's component and then, in order to satisfy the load demand in the most cost-effective way, two discrete versions of particle swarm optimization algorithm are developed to optimally size the systems components. As an efficient search method, PSO has simple concept, is easy to implement, can escape local optima, by use of probabilistic mechanisms, and only needs one initial solution to start its search. Simulation results indicate that only under a subsidized diesel fuel price scenario, the diesel-only system has the minimum cost, but by the elimination of diesel fuel price subsidies and reduce the costs of photovoltaic panels and wind turbines, the role of the diesel generator decreases in hybrid (PV/wind/diesel/battery) energy systems.

“…In the regard of combining PV-SOFC systems, different generation technologies are investigated for the residential sector to find the most suitable option concerning high energy efficiency and low CO 2 emissions. Sadeghi and Ameri [8] examine a PV/Battery system with different power generation systems, such as SOFC, micro gas turbine, gas generator and diesel generator. In this study, a multi-objective evolutionary algorithm was used to obtain the best solution of the generation system with solar panels and a battery system.…”

“…The electricity and heat demand for dwellings can be primarily covered in an efficient way, reducing fuel consumption and CO 2 emissions [5,6]. Shimoda and Taniguchi [7] compared the use of the cogeneration systems PEM, SOFC and gas engines for different household types in the Japanese residential sector, concluding that SOFC technology can reduce the CO 2 emissions significantly due to the possibility for the electricity dominated mode with a high part load capability and efficiency [8].…”

Renewable energy sources based on solar and wind energy provide clean and efficient energy. The intermittent behaviour of these sources is challenging. At the same time, the needs for efficient, continuous and clean energy sources are increased for serving both electricity and thermal demands for residential buildings. Consequently, complimentary systems are essential in order to ensure a continuous power generation. One of the promising energy sources that helps in reducing CO2 emissions, in addition to providing electrical and thermal energy efficiently, is a Solid Oxide Fuel Cell (SOFC) system operated in a combined heat and power (CHP) mode, due to high electrical efficiencies (in full and part load) and the fuel flexibility. Currently, most studies tend to focus on fuel cell model details with basic information about the building’s energy requirements. Nevertheless, a deep understanding of integrating fuel cell micro-CHP systems with renewable energy systems for the residential sector is required. Moreover, it is important to define an operating strategy for the system with a specific controlling method. This helps in evaluating the performance and the efficiency of the building energy system. In this study, an investigation of different configurations of a hybrid power system (HPS) was carried out. The intended aim of this investigation was to optimize a HPS with minimal CO2 emissions, serving the energy demands for a single-family house efficiently and continuously. As a result of this study, a photovoltaic (PV)/SOFC micro-CHP system has satisfied the intended goal, where the CO2 emissions are significantly reduced by 88.6% compared to conventional systems. The SOFC micro-CHP plant operated as a complimentary back-up generator that serves the energy demands during the absence of the solar energy. Integrating the Power to Gas (PtG) technology leads to a similar emission reduction, while the PtG plant provided a seasonal energy storage. The excess energy produced during summer by the PV system is stored in the fuel storage for a later use (during winter). This SOFC micro-CHP configuration is recommended from an energy and environmental perspective. In terms of feasibility, the costs of SOFC based micro-CHP systems are significantly higher than traditional technologies. However, further technology developments and the effect of economy of scale may cause a substantial drop in costs and the micro-CHP shall become economically competitive and available for residential users; thus, enabling a self-sufficient and efficient energy production on site.
