For that purpose, a recent fusion strategy that relies on the Maximum Correntropy Criterion (MCC) is extended by including predictive models to forecast power system behavior in the very short term. No changes are required to first-stage estimation algorithms, while the MCC properties allow for the immediate suppression of discrepant data effects.

For this purpose, reliable decision-support methods should be deployed to identify feasible and profitable microgrid operation strategies, considering the effects of the large and correlated uncertainty sources affecting the input data. To try and address this problem, this paper proposes a new formulation of the affine arithmetic counterpart of the microgrid-based flexibility scheduling problem that allows overcoming the over-conservativism of conventional range-based operators by computing a family of solutions that include the solution computed by robust optimization.

Also, the case study results show that the consideration of BESSs’ degradation costs reduces the provision of energy as well as balancing services from BESSs.

This cyclic operation causes a degradation of the storage batteries and a reduction of the available energy capacity. The operation of the asset can be improved by considering revamping actions, where the energy capacity of the asset is restored by replacing the degraded cells with brand-new ones. However, these actions require a comprehensive modelling of different types of non-negligible costs and of important operating features. For an accurate maximization of the overall profit, it becomes extremely relevant to determine the optimal timing and sizing of these revamping actions. This paper develops a scheduling model for a utility-scale battery which co-optimize the asset’s optimal <em>short-term</em> market operation while providing the optimal <em>long-term</em> revamping policy to manage the energy capacity fade pursuant to cyclic charging/discharging actions. Specifically, the optimal choices concerning the revamping policy accurately account for three features. The first acknowledges both fixed and variable costs concerning the replacement of racks of cells. The second is the downtime of the asset during each revamping period, i.e. its inability to operate in energy markets while the revamping action is being carried out. Last, the proposed methodology allows to compare the residual economic value of worn cells with respect to the current market value of brand-new ones. Results indicate a high impact of the abovementioned features on the optimal selected revamping policy as well as on the actual total profit of the battery.</div></div>","PeriodicalId":56142,"journal":{"name":"Sustainable Energy Grids & Networks","volume":"43 ","pages":"Article 101823"},"PeriodicalIF":5.6,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144739033","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 introduces a real-time rolling horizon control model specifically designed to mitigate imbalances within a Renewable Energy Community (REC). The proposed model, referred to as BAL-RT, leverages the flexibility of distributed energy storage systems by reserving a portion of their capacity exclusively for real-time imbalance compensation. Unlike many approaches in the literature, which rely on intraday market mechanisms and are difficult to apply to small-scale consumers, the BAL-RT model is conceived for practical implementation in RECs composed of prosumers and consumers with limited market access. Furthermore, the model's robustness is assessed by analyzing the impact of key parameters, including the share of storage capacity allocated to the balancing service and the measurement time resolution. Numerical results, based on a real-world case study of an Italian REC, demonstrate that the BAL-RT model can significantly reduce imbalance levels and related costs, even in the presence of increased temporal granularity.</div></div>","PeriodicalId":56142,"journal":{"name":"Sustainable Energy Grids & Networks","volume":"43 ","pages":"Article 101828"},"PeriodicalIF":5.6,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144721366","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}
