Existing research has predominantly restricted ECS cable layouts to conventional radial or ring structures and employed graph theory heuristics for solutions. However, both economic efficiency and reliability of the OWFs heavily depend on their ECS structure, and the optimal ECS cable layout often deviates from typical configurations. In this context, this paper introduces a novel reliability-based ECS cable layout planning method for large-scale OWFs, employing a two-stage stochastic programming approach to address uncertainties of wind power and contingencies. To enhance reliability, the model incorporates optimal post-fault network reconfiguration strategies by adjusting wind turbine power supply paths through link cables. To tackle computation challenges arising from numerous contingency scenarios, a customized progressive contingency incorporation (CPCI) framework is developed to solve the model with higher efficiency by iteratively identifying non-trivial scenarios and solving the simplified problems. The convergence and optimality are theoretically proven. Numerical tests on several real-world OWFs validate the necessity of fully optimizing ECS structures and demonstrate the efficiency of the CPCI algorithm.","PeriodicalId":452,"journal":{"name":"IEEE Transactions on Sustainable Energy","volume":"16 1","pages":"419-433"},"PeriodicalIF":8.6,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142250422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the DR is a passive device and cannot support the startup of the WTs. Therefore, it is worth finding an appropriate and cost-effective startup strategy for the DR-connected WTs. This paper investigates to use of wind energy to startup those WTs to avoid the need for additional grid support or the energy storage system, which can reduce the overall cost of such transmission system. The first challenge for this strategy is that the output active power of WTs can be extremely low during the startup process, which puts the WT rotor at a high risk of overspeed. Another challenge is to prevent power surges between synchronizing WTs. To address those issues, the pitch control has been innovated for the DR-connected WTs. In addition, a seamless synchronization control of the DR-connected WTs is proposed, which does not need the phase-locked-loop and can facilitate the whole startup process of the DR-connected WTs. The feasibility of these proposed control strategies for the startup of the DR-connected WTs is verified by comprehensive simulation studies.","PeriodicalId":452,"journal":{"name":"IEEE Transactions on Sustainable Energy","volume":"16 1","pages":"407-418"},"PeriodicalIF":8.6,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142250424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, this paper proposes an unsupervised zero-label learning method for power generation forecasting of newly built PV sites without relying on any historical power output data. The main idea is to extract invariant causal structures across different PV sites and leverage this causality to enhance the power forecasting performance on the newly built ones. In particular, a causality-enabled domain adaptation network (CEDAN) is designed to capture the causal mechanism of PV generation from the multiple fine-grain segments of time-lagged data. It relaxes the causal relationships to an associative structure which is further concretized as attention score vectors through the designed intra- and inter-variable attention mechanisms. To quantify the distribution discrepancies between source and target domain causal structures, a specific domain adaptation loss function is designed for the optimization of CEDAN. It is further extended to a domain adaptation quantile loss to handle the uncertainties of PV power output. By jointly minimizing the domain adaptation loss and power forecasting error/conditional quantile loss, an invariant power generation causal mechanism across data domains for a newly built PV site can be learned. This allows the proposed method to achieve accurate and highly generalized power generation forecasting for newly built PV sites without relying on labeled data. Extensive experiments utilizing real PV generation data demonstrate that the proposed method surpasses state-of-the-art transfer learning methods by 7.57% at least in deterministic forecasting and 8.37% at least in probabilistic forecasting.","PeriodicalId":452,"journal":{"name":"IEEE Transactions on Sustainable Energy","volume":"16 1","pages":"392-406"},"PeriodicalIF":8.6,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142219442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the data sets for training wind power curve models have a critical issue. A considerable proportion of the data sets is abnormal due to communication failure and other factors. Using the data sets with abnormal data will significantly deteriorate the fitting performance. This paper resolves the above issue by proposing a unified way to achieve abnormal data detection and curve fitting. Instead of regression with scalar output, set-valued regression of the wind power curve is considered, giving a set of wind power for a given wind speed. Interval neural network is adopted as the model for set-valued regression. A chance-constrained optimization problem is formulated to train an interval neural network. The obtained interval neural network can specify a subset with the normal data area, which can be used to give the threshold for abnormal data detection. Besides, the center points of the interval can be used as the fitted wind power curve. Since the formulated chance-constrained optimization problem is intractable, a sample-based sigmoidal approximation method is proposed to approximately solve it. The convergence and probabilistic feasibility of the approximation are given. Finally, experimental validations have been conducted to compare the proposed method with several existing methods.","PeriodicalId":452,"journal":{"name":"IEEE Transactions on Sustainable Energy","volume":"16 1","pages":"350-364"},"PeriodicalIF":8.6,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142219446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the participation of multiple market entities with widely different characteristics in large-scale energy systems has urged the critical need for the application of a distributed scheme to the UC problem.

The presence of a large number of binary variables in the UC subproblems, which are solved by each participating entity after implementing the UC decomposition, fails to guarantee the convergence and the optimality of existing solution methods. To bridge this gap, this paper proposes a distributed method, using logic-based Benders decomposition (LBBD), for the UC problem in a typical multi-entity system, i.e., integrated electric and heating system (IEHS). By searching the branch and bound tree of the district heating system (DHS) subproblem, the lower bound of its objective function is rigorously derived as a valid Benders cut to ensure the convergence to global optimal results. This distributed method is suitable for both deterministic and robust UC solutions.

Second frequency deeps (SFDs) are the results of such power reductions that are challenging during abrupt frequency transients that may lead to under-frequency load shedding, or cascading events leading to blackouts. To address this issue, this paper presents an adaptive inertial control (AIC) scheme for WTGs designed to maximize the improvement in frequency nadir without causing SFD. The proposed method is developed through an assessment of power reduction period of WTGs during fast frequency response. This analysis investigates the impacts on the system frequency of a) injecting different shares of disturbance size (SoDSs) by WTGs and b) latency/delay in power injection. Derived from this analysis, the AIC is proposed to inject the maximum possible SoDS during the over-production period and successfully stabilize and recover the rotor speed during the assigned optimal power reduction period with SFDs disabled. This is achieved by adaptively adjusting the AIC in the reduction period based on the SoDS injected by WTGs during the over-production stage. Also, the AIC is modified to adapt against wind speed deviations. To evaluate the performance of the AIC, a comprehensive verification is carried out by comparing AIC with thirteen existing inertial control schemes and maximum power point tracking control in various cases using wind-integrated IEEE 39-bus system in Digsilent PowerFactory and real-time experimental tests. The results confirm the effectiveness of AIC in terms of achieving maximum improvement in frequency nadir without generating SFD.","PeriodicalId":452,"journal":{"name":"IEEE Transactions on Sustainable Energy","volume":"16 1","pages":"377-391"},"PeriodicalIF":8.6,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142219443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
