Transformation of the urban energy metabolism is possible when sustainable energy is positioned as an infrastructure‐scale tool. A review of urban energy planning research is complemented by an examination of assessment methods in use to gauge the feasibility of planning sustainable energy as a new infrastructure to power cities. A case study analysis of the city of Daejeon is offered to operationalize this planning strategy. In particular, the integrated application of the “savings city” and “solar city” concepts where, respectively, citywide deployment of energy efficiency and rooftop photovoltaic energy systems is envisioned at a large‐scale, is explored for Daejeon through the innovative use of geospatial assessment methods and a visualization tool that can guide urban policy. This assessment and its visualization illustrates not only grid energy use divisions throughout the city but also reveals possible energy planning trajectories in pursuit of positioning sustainable energy as urban infrastructure. The assessment finds that cities like Daejeon could fulfill over half of their electricity service needs through in‐city deployment of sustainable energy at the infrastructure‐scale. Cities that embark on this “sustainable city” trajectory essentially reform the lived experience of “the city” and reshape the city‐energy relationship.

“…Several studies in the literature analyzed the effects of controlled charging and discharging of EVs on the grid and the associated reductions of GHG emissions [10][11][12][13][14][15][16]. Note that, in energy systems with a large share of RES, flattening the duck curve, which represents the net demand of a power system once the intermittent renewable energy production has been subtracted from the total demand [3], is similar to reducing the amount of imported GHG emissions.…”

The Potential of Vehicle-to-Grid to Support the Energy Transition: A Case Study on Switzerland

et al. 2021

Energy systems are undergoing a profound transition worldwide, substituting nuclear and thermal power with intermittent renewable energy sources (RES), creating discrepancies between the production and consumption of electricity and increasing their dependence on greenhouse gas (GHG) intensive imports from neighboring energy systems. In this study, we analyze the concurrent electrification of the mobility sector and investigate the impact of electric vehicles (EVs) on energy systems with a large share of renewable energy sources. In particular, we build an optimization framework to assess how Evs could compete and interplay with other energy storage technologies to minimize GHG-intensive electricity imports, leveraging the installed Swiss reservoir and pumped hydropower plants (PHS) as examples. Controlling bidirectional EVs or reservoirs shows potential to decrease imported emissions by 33–40%, and 60% can be reached if they are controlled simultaneously and with the support of PHS facilities when solar PV panels produce a large share of electricity. However, even if vehicle-to-grid (V2G) can support the energy transition, we find that its benefits will reach their full potential well before EVs penetrate the mobility sector to a large extent and that EVs only contribute marginally to long-term energy storage. Hence, even with a widespread adoption of EVs, we cannot expect V2G to single-handedly solve the growing mismatch problem between the production and consumption of electricity.

“…Integration of household PV systems and electric vehicle use are a promising solution for global GHG reduction and locally lower fuel costs [17,18]. Energy analysis from Kyoto, with limited areas intended for RES, indicated 74% CO2 emission and 37% cost reduction from the power and transport sectors by applying photovoltaic rooftop systems and electric vehicles [19]. Results from 12 stands at an EV charging station equipped with photovoltaic panels (48 kW) and Li-ion 100 kW battery energy storage show the possibility of achieving 100% renewable electricity using appropriate control modes [20].…”

Experimental Analysis of Residential Photovoltaic (PV) and Electric Vehicle (EV) Systems in Terms of Annual Energy Utilization

Electrification of powertrain systems offers numerous advantages in the global trend in vehicular applications. A wide range of energy sources and zero-emission propulsion in the tank to wheel significantly add to electric vehicles’ (EV) attractiveness. This paper presents analyses of the energy balance between micro-photovoltaic (PV) installation and small electric vehicle in real conditions. It is based on monitoring PV panel’s energy production and car electricity consumption. The methodology included energy data from real household PV installation (the most common renewable energy source in Poland), electric vehicle energy consumption during real driving conditions, and drivetrain operating parameters, all collected over a period of one year by indirect measuring. A correlation between energy produced by the micro-PV installation and small electric car energy consumption was described. In the Winter, small electric car energy consumption amounted to 14.9 kWh per 100 km and was 14% greater than summer, based on test requirements of real driving conditions. The 4.48 kW PV installation located in Poznań produced 4101 kWh energy in 258 days. The calculation indicated 1406 kWh energy was available for EV charging after household electricity consumption subtraction. The zero-emission daily distance analysis was done by the simplified method.
