Special Issue Information

Dear Colleagues,

Recently, global warming has become one of the main issues globally. One of the causes of global warming is the increase of greenhouse gas emissions. Therefore, the efficient utilization of energy is necessary for the reduction of emissions, and smart city demonstration (SC) projects have been conducted all over the world in order to reduce the total energy used and the amount of CO2 emissions. Using various technologies, including renewable energies such as solar and wind power generation, storage batteries, and recent information technologies, SC can realize sustainable and low carbon emission cities. All countries attending the UN climate change conference 2015 (COP21) proposed the goal to reduce the amount of CO2 in 2015. The importance of SC is increasing all over the world as a reduction of the amount of CO2 emissions was again recognized at the COP21.

In order to realize smart cities, research has to be conducted in various sectors, and this will be the focus of this Special Issue. Topics of interest for publication include, but are not limited to:

- Smart energy management in factories, buildings, and houses,

- Energy efficiency in drinking water and wastewater treatment plants,

- Energy efficiency in trains and automobiles, and networks of these,

- Energy efficiency in electric power systems,

- Energy efficiency in whole cities.

Hybrid energy systems (HESs) generate electricity from multiple energy sources that complement each other. Recently, due to the reduction in costs of photovoltaic (PV) modules and wind turbines, these types of systems have become economically competitive. In this study, a mathematical programming model is applied to evaluate the techno-economic feasibility of autonomous units located in two isolated areas of Ecuador: first, the province of Galapagos (subtropical island) and second, the province of Morona Santiago (Amazonian tropical forest). The two case studies suggest that HESs are potential solutions to reduce the dependence of rural villages on fossil fuels and viable mechanisms to bring electrical power to isolated communities in Ecuador. Our results reveal that not only from the economic but also from the environmental point of view, for the case of the Galapagos province, a hybrid energy system with a PV–wind–battery configuration and a levelized cost of energy (LCOE) equal to 0.36 $/kWh is the optimal energy supply system. For the case of Morona Santiago, a hybrid energy system with a PV–diesel–battery configuration and an LCOE equal to 0.37 $/kWh is the most suitable configuration to meet the load of a typical isolated community in Ecuador. The proposed optimization model can be used as a decision-support tool for evaluating the viability of autonomous HES projects at any other location. Full article
