“…In the literature, various benefits have been mentioned for EVSC. The effectiveness of EVSC in reducing charging costs for a case in Europe (including Belgium and Germany) by 15-30 % and decreasing CO 2 emissions by 600,000 t per year by 2030 compared to unmanaged charging has been mentioned in [106]. This reference has also mentioned the influence of EVSC in reducing renewable curtailment in California by 40 % and the power grid operational costs by 10 % by 2025.…”

Impact of Dynamic Electricity Tariff and Home PV System Incentives on Electric Vehicle Charging Behavior: Study on Potential Grid Implications and Economic Effects for Households

The rapid increase of electric vehicles (EVs) would lead to a rise in load demand on power grids but create different potential benefits as well. Those benefits comprise EVs serving as a mobile energy storage system to participate in adjusting the load on the power grids and helping manage renewable energy resources. This paper evaluates the effect of dynamic electricity prices and home photovoltaic (PV) system incentives on users’ EVs charging behavior and potential impacts on grid load and household economy. This has been done by establishing and assessing three different optimized charging configurations and comparing them to an uncontrolled charging strategy. In this study, the charging incentives are applied to a representative sample of 100 households with EVs and PV systems in a metropolitan area. The results show that an optimized charging strategy based on the dynamic electricity tariff can reduce charging costs by 18.5%, while a PV-based optimized strategy can reduce the costs by 33.7%. Moreover, the PV-integrated optimization strategies significantly increase the utilization of PV energy by almost 46% on average, compared to uncontrolled charging. In addition, the simulations of this research have depicted the capability of using home PV systems’ incentives to smoothen the charging profiles and hence significantly reduce the maximum grid load. However, the electricity price optimization strategy increases the aggregated charging peaks, which can only be slightly reduced by peak shaving. Therefore, an identical price signal for all households might be critical. Further analyses have shown that direct charging occurs simultaneously with household electricity assigned to a specific low-voltage grid while PV and price incentive charging configurations shift the charging peaks away from household load peaks.

“…This paper uses MC to describe ''unidirectional power flow management,'' unlike bidirectional charging, known as vehicle-to-grid (V2G). V2G enables a PEV (specifically a BEV) to discharge energy to the grid (60).…”

“…Given a pool of 1,000 PEVs, about 1.2 MW of power could be shed during a typical weekday night in December if needed, suggesting that flexible loads can reduce the need to dispatch inefficient power plants to reduce emissions. If a California grid is assumed, each PEV could reduce over 10% of their annual CO 2e emissions.A joint utility-OEM study recorded driving records from nearly 400 PEV owners in Northern California and discovered an additional 32% of GHG emissions could be reduced if all charging sessions were managed ( 60 , 83 ). This assumption requires that all trip destinations had access to utility-controlled EVSE and mobility constraints were met and known in advance.…”

Vehicle electrification delivers fast decarbonization benefits by significantly improving vehicle efficiency and relying on less carbon-intense feedstocks. As power grids transition away from carbon-intensive generation and battery energy density improves, the transportation sector’s greenhouse gas savings may deliver upwards of a 75% reduction in current carbon footprint for many nations. Actual savings depend on many variables, like power grid feedstocks, charging rates and schedules, driver behavior, and weather. A special synergy between power and transportation sectors comes via managed charging and second-life battery uses for energy storage systems. This paper reviews the added carbon and energy savings that can come from these two strategies. If charging stations are widely available at one’s destination, utility-controlled managed charging could reduce emissions from electric vehicle charging by one-third. Downcycling electric vehicle batteries for energy storage can also lower peaker power plant use, avoid curtailment of renewable feedstocks, and lessen households’ power-based carbon footprints by half—or contribute up to 5% of grid power capacity.
