“…Besides, a radical shift to a decarbonize energy supply will be required to stable the atmospheric concentrations of CO 2 which leads a significant climate change mitigation. So, it is very urgent to arrange the renewable energy resources for this critical issue [3,4]. Usage of renewable energy resources for electricity generation is a priority research topic for this situation.…”

The enormous percentage of people in the world; particularly in the developing countries; are living mostly in decentralized, rural and remote areas, those are geographically secluded from the main grid connection. The power distribution and continuous fuel transportation to generate electricity for these areas pretenses a very big challenge. By proper utilization of renewable energy resources in off grid hybrid energy systems will be an efficient solution of this crisis. Moreover, the high cost of renewable energy systems has led to its slow adoption in many developing countries. Hence, it is very important to find an appropriate size of system in order to reduce the energy cost and excess electricity generation as well as to maximize the available resources. Therefore, a hybrid energy system has been designed and simulated to support a small community considering an average load demand of 85 kWh/d with a peak load of 8.7 kW. The simulation and optimization of the system have been performed by the HOMER software using real time field data of solar radiation, wind speed and biomass of that particular area. The simulation results confirm that the system is suitably feasible with respect to the net present cost (NPC) and CO 2 emission reduction purpose. The simulation results also confirm that the NPC and CO 2 emission can be reduced about 32.45% and 29 tons per year respectively compared to the conventional power plants. The NPC of the optimized system has been found about USD $160,626 having per unit Cost of Energy

Abstract:The potential for using heat generated during the compression stage of a Compressed Air Energy Storage system was investigated using exergy and exergoeconomic analysis. Two Compressed Air Energy Storage systems were analysed: Compressed Air Energy Storage (CAES) and Compressed Air Energy Storage combined with Thermal Storage (CAES-TS) connected to a district heating network. The maximum output of the CAES was 100 MWe and the output of the CAES-TS was 100 MWe and 105 MWth. The study shows that 308 GWh/year of electricity and 466 GWh/year of fuel are used to generate 375 GWh/year of electricity. During the compression of air 289 GWh/year of heat is generated, which is wasted in the CAES and used for district heating in the CAES-TS system. Energy efficiency of the CAES system was around 48% and the efficiency of CAES-TS was 86%.Exergoeconomic analysis shows that the exergy cost of electricity generated in the CAES was 13.89 ¢/kWh, and the exergy cost of electricity generated in the CAES-TS was 11.20 ¢/kWh. The exergy cost of heat was 22.24 ¢/kWh in the CAES-TS system. The study shows that CAES-TS has the potential to be used both as energy storage and heat source and could be a useful tool for balancing overall energy demand and supply.

“…In particular, households cause 25% of the total green house gases emission related to fossil fuel combustion in the EU (European Environmental Agency, 2012). To mitigate their impact on both energy consumption and pollutant emissions, several technological alternatives are available in terms of energy generation systems, such as: i) an increase in the renewable energy penetration (Franco and Salza, 2011;Cozzolino et al, 2016;Lau et al, 2010); ii) distributed generation (DG) and cogeneration (CHP) or trigeneration (CHCP) (Onovwiona and Ugursal, 2006;Chicco and Mancarella, 2009;Jannelli et al, 2014a); iii) mechanical, electrical or thermal energy storage (Marano et al, 2012;Facci et al, 2014c;Jannelli et al, 2014b). Regarding DG, the definition of (Ackermann et al, 2001) should be taken as a reference, that is an electric power source connected directly to the distribution network or on the customer site of the meter.…”

The optimal design of distributed generation systems is of foremost importance to reduce fossil fuel consumption and mitigate the environmental impact of human activities in urban areas. Moreover, an efficient and integrated control strategy is needed for each of the components of a distributed generation plant, in order to reach the expected economic and environmental performances.In this paper, the transition from natural gas to electricity-based heating is evaluated for residential applications, considering the interplay between photovoltaic electricity produced on site and the thermal energy storage, to grant the optimal management of heating devices. The energy demand of an apartment building, under different climatic conditions, is taken as a reference and four power plant solutions are assessed in terms of energy cost and pollution reduction potential, compared to a baseline plant configuration. The performance of each power plant is analyzed assuming an optimized control strategy, which is determined through a graph-based methodology that was previously developed and validated by the authors. Outcomes from our study show that, if heat pumps are used instead of natural gas boilers, energy costs can be reduced up to 41%, while CO 2 emissions can be reduced up to 73%, depending on the climatic conditions.Our results provide a sound basis for considering the larger penetration of photovoltaic plants as an effective solution towards cleaner and more efficient heating technologies for civil applications. The simultaneous utilization of heat pumps (as substitutes of boilers) and photovoltaic panels yields a positive synergy that nullifies the local pollution, drastically cuts the CO 2 emission, and guarantees the economical sustainability of the investment in renewable energy sources without subsidiary mechanisms.
