Firstly, the users participating in the smart contract and the VPP within the region are regarded as different interest subjects. And the maximum opportunity benefit of users is taken as the internal optimization goal. Secondly, taking the overall benefit maximization of the VPP as the overall optimization objective,. Thus, a two-layer optimal scheduling model including energy storage is established, and the multi-objective particle swarm optimization algorithm was applied to solve the problem. The local consumption of new energy is taken as the criterion, and the price of some local consumption energy is determined by the bidding mechanism of producers and sellers. Finally, the thermal power units are used as auxiliary units. In the two scenarios with or without energy storage, comparative tests are made on the internal trading of the energy layer of VPPs. The optimal scheduling results show that the internal trading of the energy layer of VPP contributes to the local consumption of new energy and improves the overall internal income level of VPP.","PeriodicalId":165790,"journal":{"name":"2023 International Conference on Future Energy Solutions (FES)","volume":"44 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132936369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Energy in buildings is mainly produced by PV solar panels. As a result, the energy production profile is highly variable and out of balance with the energy consumption profile, resulting in peak demand on the electricity grid. Energy flexible buildings, i.e. buildings that can adapt their grid energy demand to the grid energy supply at any time, could reduce the impact of the widespread use of renewable energy production on the electricity grid. Current methods for assessing the energy flexibility of buildings use dynamic energy data, mainly generated by building energy simulations. This type of method makes it difficult to assess large building portfolios. This paper presents a method that provides an indication of the energy flexibility characteristics of buildings based on static data about the characteristics of the building and building services. The method analyses the building characteristics with a set of 32 questions divided into 11 categories and derives from them an estimate of the main energy flexibility indicators: amount of power, amount of energy, amount of time and speed at which the energy consumption of the building can deviate from the reference profile. The method makes it possible to identify which building elements can be modified in order to increase the energy flexibility of the building. This type of information can facilitate the development of a real state strategy to increase the energy flexibility of the building portfolio of large organisations, resulting in a significant positive impact on the national electricity grid. The proposed method is a first attempt to create a rapid energy flexibility assessment method and should be further developed to validate its accuracy and investigate the effect of combinations of building parameters.","PeriodicalId":165790,"journal":{"name":"2023 International Conference on Future Energy Solutions (FES)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133186665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finally, an assessment framework is established to evaluate the benefits of implementing DR programs on the energy costs and the individual profit of the WPP. Also, effective metrics are implemented to the problem to evaluate the effect of implementing DR programs on the market power of the WPP.

When using FCS-MPC, the switching frequency is not fixed, which leads to a more complex design of the converter filter. In this work, a new method is given to guarantee that the input current ripple is limited to a predetermined level when the converter is operating as a dc-grid former, and the output voltage ripple is limited for the ac grid-former operation.

Previous literature has reported that the wake region of the VAWT is not symmetric, and its downstream is similar to a circular cylinder wake street. The airflow of the VAWT is turbulent, and the inviscid incompressible flow can be applied to its range. Therefore, the current study analyzed the flow over a cylinder with circulation to investigate the velocity, pressure coefficient, and tip speed ratio and to observe the similarity between the cylinder and the VAWT. The results of this study demonstrate remarkable similarity, particularly with respect to the asymmetry of the wake region due to the distinct velocity speed in two opposite locations of the VAWT. Moreover, the pressure coefficient functionality and curvature are similar to the available measurements of the VAWT. This model can be further developed and examined under varied conditions to provide a theoretical wake loss model for VAWTs. This will lead to the expansion of VAWTs’ applications in green, sustainable, and clean energy production.","PeriodicalId":165790,"journal":{"name":"2023 International Conference on Future Energy Solutions (FES)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132723960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we propose an open-source LEM model for matching prosumers and consumers with the same energy and price policy in a decentralized LEM. Our model was verified of its applicability by simulating it with the data from a German community. The simulation results showed that the model was able to satisfy the energy preferences of the consumers and prosumers in the local community to an average of more than 60%.
