In this paper, a novel interpolation-based method is proposed for performing fast and accurate dynamic simulations of electric power systems equipped with smart digital controllers. This method fully exploits the potential of variable time-step integration methods without requiring a time-step reduction in the case of discrete events stemming from digital controllers. Therefore, it accelerates the numerical simulation of large-scale systems containing many non-equation-based smart digital controllers, while maintaining accuracy.

In the residential scope, demand response can be realized with heat pumps and electric vehicles. Recent research has already quantified the flexibility potential of heat pumps and electric vehicles. However, none of this research considers the communication protocols used in practical applications. The novelty of the current work is that it analyzes the influence of different real-world communication protocols on the flexibility potential of heat pumps and electric vehicles. Therefore, models for heat pumps and electric vehicles with different communication protocols are developed and verified with measurement data. To determine the flexibility potential, 200 randomized instances of these models are simulated over one year for each communication protocol. The results show that the downward flexibility potential of heat pumps is independent of the communication protocol. The upward flexibility potential of heat pumps is highest and most stable with direct load control over <em>Modbus</em>. Unlike downward flexibility, upward flexibility increases the daily energy consumption of heat pumps. For electric vehicles, ISO 15118-20 shows the highest overall flexibility.</div></div>","PeriodicalId":56142,"journal":{"name":"Sustainable Energy Grids & Networks","volume":"42 ","pages":"Article 101662"},"PeriodicalIF":4.8,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143520404","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}

This paper defines a novel method to the improve economic aspect of distributed energy resources (DERs) in a distribution network through a VPP framework, actively contributing in day-ahead and regulation reserve markets. One of the main novelties of this study is using a forecasted price-based unit commitment approach for VPPs in microgrids with the aim of determining an optimal pricing strategy though addressing real-world operational complexities. Also, this study integrates a dual-role EV parking lots, acting both as a consumer and electricity provider, and explores its potential to minimize costs while optimizing charging and discharging agendas. The proposed optimization model tries to obtain maximum VPP profits in day-ahead and reserve markets by controlling the complexities of distributed thermal and electrical production, energy storage limits, and power balance restraints. By implementing an efficient model based on the a mixed-integer linear programming (MILP), a higher solution speeds, global optimality, and scalability for larger problems overcoming traditional limitations such as local optima and infeasibility in large-scale scenarios is achieved. By considering the uncertainties of solar and wind sources, a spinning reservation technique is used to increase microgrid stability. This study also examines how demand response programs help gas stations operate better and facilitate effective energy transfers between VPPs and the upstream network.

The concept of the system is based on a time-discretized scheduling approach that incorporates all relevant assets at the hub to charge the EVs without creating grid congestion problems. Since EV charging schedules in general have to be determined based on incomplete and often inaccurate forecasts and information, the scheduler is combined with an online control policy that operates to compensate for forecast errors or that can be used to react on external market price signals or congestion information. A simulation study of the scheduling concept and its underlying model shows that incorporating the current peak-tariff structure used in the Netherlands into the EMS can contribute to reducing the peak demand on the grid throughout the year for the proposed charging hub by 8.4%. The simulations furthermore show that the application of a peak shaving approach can lead to a peak load reduction of up to 36%, at only a 2.6% increase in total operational costs. The research objective of this study is to investigate how the theoretical model of the EMS can be applied in a real-world implementation. For this, the EMS is implemented in a real-life operational demonstration of the concept with real devices, data and users. The demonstration of the EMS in a real-world implementation advances the state of knowledge on these topics by demonstrating conflicting interests the lack of information-exchange between different stakeholders and the effect of this on the EV charging ecosystem.
