“…The algorithm behind the mono objective optimization ensures elitism by making use of an archive (secondary population), while the one behind the multi objective optimization relies on the principles of Strength Pareto Evolutionary Algorithm (SPEA). [82][83][84][85] In this analysis is opted for the multi-objective type optimization, and the criteria with minimization function by which it was achieved are the following: total system cost, carbon dioxide emissions, unmet load, excess energy and rated power/component equipment related to energy demand assurance.…”

The Electric Vehicle (EV) as a clean alternative to Classic Vehicle that use fossil fuels is promoted as an immediate solution to improve the quality parameters of the environment related to the transport sector. The transition to clean electrified mobility must be considered from the sustainability spectrum, and the planning of a strategy related to the implementation of electric vehicles implies, from the beginning, providing clean energy conditions to go toward a green-to-green paradigm. It should be noted that the successful implementation of the "green electro mobility" concept depends heavily on the green energy supply solutions of green electric vehicle, so Electric Vehicle Charging Stations (EV-CS) should be powered by electricity generation systems based on green resources. This research article has as main objective the environmental impact assessment from the perspective of CO 2 emissions embedded in green stand-alone energy systems and the estimation of the environmental benefits of their implementation in the power supply of EV-CS from the perspective of avoided CO 2 emissions compared to the classic electricity supply grid. The results indicate that the green energy systems represent feasible solutions for the independent energy support of electric vehicle charging stations, being able to supply electricity based on on-site available 100% alternative energy sources. Related to 1 kWh of electricity, the CO 2 emissions embedded in these systems represent on average 11.40% of the CO 2 emissions of the electricity supplied through the grid at European level and on average 7.10% of the CO 2 emissions of the electricity supplied through the grid worldwide. Results also show that the average price of 1kWh of electricity generated by the analyzed systems is 4.3 times higher than the average unit price of the European Union grid energy, but this indicator must be correlated with the kgCO 2 /kWh cost savings compared to the electricity production from classic power plants.

“…If there is an excess of power generated from the PV and WT sources the electrolyser will produce hydrogen which will be stored for further consumption. In the case the energy generated from RES is not enough to supply the entire building the fuel cell will generate the required power using the already stored hydrogen [12,15,16].…”

This contribution presents a comparative study of operating a green energy hybrid system to sustain the power production mix of an office building. For this purpose, two scenarios of a hydrogen storage system (S1) and battery energy storage (S2) to sustain solar and wind energy inlets were compared from a technical, environmental and financial perspectives. S1 - hydrogen technology system was found to be more performing than S2 - battery technology in terms of energy efficiency, as well as CO2 emissions and initial costs.

A price-regulated electric vehicle charge-discharge strategy for G2V, V2H, and V2G

Summary Electric vehicles (EVs) and smart grids are gradually revolutionising the transportation sector and electricity sector respectively. In contrast to unplanned charging/discharging, smart use of EV in home energy management system (HEMS) can ensure economic benefit to the EV owner. Therefore, this paper has proposed a new energy pricing controlled EV charging/discharging strategy in HEMS to acquire maximum financial benefit. EV is scheduled to be charged/discharged according to the price of electricity during peak and off‐peak hours. In addition, two different types of EV operation modes, ie, grid‐to‐vehicle (G2V) in off‐peak time and vehicle‐to‐home (V2H) in on‐peak time are considered to determine comparative economic benefit of planned EV charging/discharging. The real load profile of a house in Melbourne and associated electricity pricing is selected for the case study to determine the economic gain. The simulation results illustrate that EV participating in V2H contributes approximately 11.6% reduction in monthly electricity costs compared with G2V operation mode. Although the facility of selling EV energy to the grid is not available currently, the pricing controlled EV charging/discharging presented in the paper can be used if such facility becomes available in the future.
