This increased uncertainty poses challenges for accurate long-term EC forecasting. Due to the complexities of feature extraction and the absence of labelled data, conventional supervised learning-based forecasting methods, such as support vector machines (SVM) and long short-term memory networks (LSTM), struggle to predict EC with precision in situations of heightened uncertainty resulting from the interplay of multiple factors. To address this issue, a novel method based on a conditional generative adversarial network (CGAN) is proposed. Initially, the dominant factors influencing future electricity consumption trends through grey correlation degree analysis and the K-L information method are identified. Subsequently, an EC forecast model is introduced based on CGAN, adept at capturing essential factors and the non-linear relationship between EC and exogenous factors. This approach effectively models the uncertainty of EC, accurately approximating the true distribution with only a small dataset. Finally, the proposed method by forecasting China's EC from 2015 to 2020 is validated. The results demonstrate that the authors’ method achieves lower root mean square error and mean absolute percentage error values, specifically 0.177% and 2.39%, respectively, outperforming established advanced methods such as SVM and LSTM.</p>","PeriodicalId":33288,"journal":{"name":"IET Energy Systems Integration","volume":"6 4","pages":"437-450"},"PeriodicalIF":1.6,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/esi2.12138","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139784847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under the SCSI scheme, a supercapacitor is added to the DC side of each wind turbine generator via a bidirectional DC/DC converter, varying its voltage along with the offshore frequency to synthesise the desired inertial response. The HVDC grid side VSC employs a DC voltage/frequency droop control to convey the onshore frequency information to DC voltage without communication.

A robust optimisation model for the distributed cooperation of MG-CES is presented, taking into account distributed generation under uncertainty. The proposed model follows a two-stage, four-layer ‘min-min-max-min’ structure. In the first stage, the initial layer ‘min’ addresses the distributed cooperation problem between MG and CES, while the second stage employs ‘min-max-min’ to optimise the scheduling of MG. To enhance the solution process and expedite convergence, the authors introduce a column-constrained generation algorithm with alternating iterations of U and D variables (CCG-UD) specifically designed for the three-layer structure in the second stage. This algorithm effectively decouples subproblems, contributing to accelerated solutions. To tackle the convergence challenges posed by the non-convex MG-CES model, the authors integrate the Bregman alternating direction method with multipliers (BADMM) with CCG-UD in the final solution step. Real case tests are conducted using three zone-level MGs to validate the efficacy of the proposed model and methodology.

Utility-scale solar PV plants have a huge potential for participation in frequency and voltage regulation since they are linked to the grid through power electronic interfaces with flexible, decoupled control of active and reactive power. A comprehensive control strategy for a utility-scale solar PV plant is proposed to simultaneously participate in frequency and voltage control without the aid of any energy storage. The frequency response is accomplished by maintaining some active power reserves that enable the PV plant to participate in both over- and under-frequency events. The active power of the PV plant is modulated by operating the PV as a virtual synchronous generator (VSG). Unlike the classic notion of VSG, an intelligent fuzzy-based technique is employed to adapt the gains of the VSG controller for improved control performance. Additionally, an adaptive droop-based voltage control mechanism is proposed to control the reactive power reference for the PV plant. The gain of the droop controller is adapted to the varying maximum reactive power capacity of the PV plant. This ensures that the PV system's unused reactive power capability is fully utilised. Through simulation studies, the efficiency of the proposed frequency and voltage control mechanisms is validated under a range of realistic circumstances. The findings show that the suggested control approach can efficiently leverage the PV plants' capacity to handle both frequency and voltage events.</p>","PeriodicalId":33288,"journal":{"name":"IET Energy Systems Integration","volume":"6 4","pages":"386-405"},"PeriodicalIF":1.6,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/esi2.12134","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139525370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
