Special Issue Information

Dear Colleagues,

The energy world is being challenged by the so-called “three-D’s”—decarbonization, decentralization, and digitalization.  Future power systems will be characterized by very large penetrations of renewables (towards 100%), supporting the operation of both central and local markets, as well as the existence of a wide range of distributed energy resources, such as intelligent micro-grids and aggregation services that are able to participate in the different market layers in a cost-effective way. Electric vehicles are expected to play a key role in future power systems. While the integration of small EV fleets typically has minimal effects on distribution grids, large-scale adoption presents significant challenges. These include potential issues with grid adequacy, operational security, and power quality. At the transmission and generation level, impacts may include erratic power flows, insufficient reserves, grid stress, and shifts in marginal generation units—ultimately influencing electricity market prices. To adress these challenges, one viable approach involves a synergistic integration of EVs into smart grids through demand-side management. This strategy enables controlled EV charging aligned with both grid constraints and user preferences, reducing the need for costly infrastructure upgrades. Additionally, it opens the door for EVs to offer new balancing and regulation services, supporting the evolution from centralized systems to decentralized, intelligent energy networks. EV owners could also benefit through appropriate compensation for their contributions to grid stability.

This Special Issue seeks to contribute to the agenda of “Sustainable Transportation: Impact on Power Systems and Future Energy Markets” by considering a multi-disciplinary approach. We therefore invite papers on innovative technical developments, reviews, models, analytical aspects, and case studies, as well as simulation-based and assessment papers, from the various disciplines related to the main activities of power systems, i.e., the generation, transport, distribution, and consumption of electrical energy.

Many electricity providers are offering their customers an array of tariff options intended to discourage electricity consumption at specific times of the day. The problem facing a customer is whether to switch from their existing tariff to a new tariff. The aim of this paper is twofold: first, to develop two analytical methods that help residential customers evaluate when switching from a flat-rate tariff to time-varying pricing options, specifically the Time-of-Use (TOU) tariff and an event-based tariff, becomes economically beneficial, and second, to review customers’ experiences with the tariffs. The methods identify the specific consumption distributions at which the TOU or event-based tariffs are in energy- and cost-equilibrium with the domestic service tariff for residential customers. For the TOU structure, the analysis shows that customers must maintain a non-winter-to-winter-peak consumption ratio exceeding 3.0756 for cost neutrality, a condition rarely met by households with winter-dominant loads. In contrast, event-based structures require only minimal behavioral adjustments to achieve savings, with as little as 1.75% of annual consumption needing to be avoided during event periods to match domestic-service costs. Additional savings are observed with partial or full load shifting away from peak events. The findings highlight that while TOU may benefit households with high summer usage, event-based tariffs present a more practical and economically favorable option for residential customers living in the Canadian province of Nova Scotia. The paper concludes with implications for tariff selection and consumer behavior. This research will be of value to anyone considering designing a time-varying rate or having to choose between an existing flat-rate tariff and a time-varying tariff. Full article

This study aims to provide an efficient framework for the coordinated integration of AC and DC chargers, intermittent solar Photovoltaic (PV) Distributed Generation (DG) units, and a Distribution Static Compensator (DSTATCOM) across residential, commercial, and industrial zones of a Radial Distribution Network (RDN) considering the benefits of various stakeholders: Electric Vehicle (EV) charging station owners, EV owners, and distribution network operators. The model uses a multi-zone planning method and healthy-bus strategy to allocate Electric Vehicle Charging Stations (EVCSs), Photovoltaic Distributed Generation (PVDG) units, and DSTATCOMs. The proposed framework optimally determines the numbers of EVCSs, PVDG units, and DSTATCOMs using Harris Hawk Optimization, considering the maximization of techno-economic benefits while satisfying all the security constraints. Further, to showcase the benefits from the perspective of EV owners, an EV waiting-time evaluation is performed. The simulation results show that integrating EVCSs (with both AC and DC chargers) with solar PVDG units and DSTATCOMs in the existing RDN improves the voltage profile, reduces power losses, and enhances cost-effectiveness compared to the system with only EVCSs. Furthermore, the zonal division ensures that charging infrastructure is distributed across the network increasing accessibility to the EV users. It is also observed that combining AC and DC chargers across the network provides overall benefits in terms of voltage profile, line loss, and waiting time as compared to a system with only AC or DC chargers. The proposed framework improves EV owners’ access and reduces waiting time, while supporting distribution network operators through enhanced grid stability and efficient integration of EV loads, PV generation, and DSTATCOM.
