This causes changes in load demand, which is responsible for grid imbalances, price changes, higher grid maintenance costs, and a higher chance of power outages, especially in low-voltage grids. This work focuses on enhancing the profit for EVCS while concurrently minimizing the charging cost for EVs owners by using coordinated charging of EVs at EVCS. The better coordinated charging of EVs increases the profit of each EVCS and lowers the cost of charging for EVs owners. This paper proposes a Monte Carlo simulation-based bi-level coordinated transactive energy trading mechanism. In the first part, the Monte Carlo simulation coordinates the EVs charging process based on their respective arrival time at the EVCS, where as in the second part, a cooperative game theory-based energy trading mechanism has been modeled to trade energy in the transactive energy market through the Distribution System Operators(DSO) with different EVCSs. The proposed coordinated charging approach enhances the profitability of all EVCSs as compared to the other existing method. The proposed technique has been implemented and validated on a modified IEEE-33 bus system.</div></div>","PeriodicalId":56142,"journal":{"name":"Sustainable Energy Grids & Networks","volume":"42 ","pages":"Article 101712"},"PeriodicalIF":4.8,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143820385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the main hurdles to understand their impact on the LVG is the lack of recent, large electricity consumption datasets, measured in real-world conditions. We investigated the contribution of LCTs to the size and timing of peaks on LV feeders by using a large dataset of 42,089 smart meter profiles of residential LVG customers. These profiles were measured in 2022 by Fluvius, the Distribution System Operator (DSO) of Flanders, Belgium. The dataset contains customers that proactively requested higher-resolution smart metering data, and hence is biased towards energy-interested people. LV feeders of different sizes were statistically modeled with a profile sampling approach. For feeders with 40 connections, we found a contribution to the feeder peak of 1.2 kW for a HP, 1.4 kW for an EV and 2.0 kW for an EV charging faster than 6.5 kW. A visual analysis of the feeder-level loads shows that the classical duck curve is replaced by a night-camel curve for feeders with only HPs and a night-dromedary curve for feeders with only EVs charging faster than 6.5 kW. Consumption patterns will continue to change as the energy transition is carried out, because of <em>e.g</em>. dynamic electricity tariffs or increased battery capacities. Our introduced methods are simple to implement, making it a useful tool for DSOs that have access to smart meter data to monitor changing consumption patterns.</div></div>","PeriodicalId":56142,"journal":{"name":"Sustainable Energy Grids & Networks","volume":"42 ","pages":"Article 101705"},"PeriodicalIF":4.8,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143834107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is an urgent need to incorporate faster frequency reserves that can stabilize the system and enhance its resilience and reliability.

To tackle this issue this paper addresses a tri-stage stochastic framework for cyber-physical attack resilient expansion planning for a smart distribution network (SDNEP<sup>CPAR</sup>) that supplies active microgrids (AMGs). The main contribution of this paper is to provide an integrated framework for expansion planning based on improving the resiliency of the electrical network against CPAs. Therefore, this paper investigates the impact of a false data injection attack on the AMGs’ electricity transactions, separately and as part of a broader group of attacks including load redistribution and physical attacks that can affect the operability of the distribution network. This framework employs an integrated resource planning mitigation strategy, including demand response programs, network reconfiguration, and rescheduling of resources to reduce the impact of attacks. In the initial stage, the network structure, the locations of the devices, their capacities and installation time, and the optimal transactions of the AMGs are determined, considering uncertain parameter scenarios. In the subsequent stage, the optimal CPA vector and the resiliency index are determined to maximize the operational cost while adhering to attack constraints. In the final stage, the optimal integrated resource planning mitigation strategy is determined to increase the power system’s resiliency.

Practically, energy hubs (EH) and Hydrogen refueling stations (HRS) could provide an ideal environment for integrating such technologies. However, the management process involves several conflicting objectives that must be met to a satisfactory extent. In this regard, this paper proposes a stochastic bi-level tri-objective optimization framework for the planning and operation of EHs and on-site green/blue HRSs. The multiple objectives involve total cost (i.e., capital, operation and maintenance, Hydrogen, and emissions), load profile deviation resulting from engaging the demand response program (DRP), and the dissatisfaction of fuel cell electric vehicles (FCVs) owners. The proposed model forms a bi-level optimization strategy. The upper-level optimization (i.e., planning level) optimizes the sizes and locations of renewable energy sources (RESs) along with the capacities, rates, and locations of the other resources (i.e., photovoltaic, wind turbine, Hydrogen storage system, thermal storage system) integrated into both EHs and HRSs incorporated into the IEEE-69 system. On the other hand, the lower level (i.e., operation level) precisely optimizes the charging and discharging profiles of the different resources incorporated in EHs and HRSs along with FCVs. The Pareto optimal solution is employed to find the best-compromised solution among the conflicting tri-objective solutions. The simulation results demonstrate that the green-controlled approach has validated its superiority for net-zero emissions transition with a 10.74 % reduction in emissions costs at almost the same total cost compared to the other approaches (i.e., blue-uncontrolled, blue-controlled, green-uncontrolled).</div></div>","PeriodicalId":56142,"journal":{"name":"Sustainable Energy Grids & Networks","volume":"42 ","pages":"Article 101690"},"PeriodicalIF":4.8,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
