Policy instruments, like carbon taxes and forcing coal plants to retire through various mechanisms, could help achieve the target. It is critical to analyze and compare decarbonization policies as different policies lead to different costs, emissions pathways, and political challenges. In this paper, we explore the ramifications of adopting alternative decarbonization policies. We assume a particular carbon tax to be the benchmark policy and compare it to alternative carbon tax and forced coal retirement policies in terms of emissions and costs. We use a power system dispatch model that co-optimizes unit commitment, energy, and frequency regulation capacity to simulate system evolution over multiple years, including retirements and renewables/storage expansion, under each policy. Our case study highlights the trade-offs between policies. We find that, counter-intuitively, higher carbon taxes do not always achieve lower emissions due to the complexity of dispatch, resulting profits and retirements, and the addition of renewables/storage. In contrast, forced coal retirements result in lower power system costs but higher emissions than the benchmark policy, with a large range of possible outcomes across different retirement cases.","PeriodicalId":452,"journal":{"name":"IEEE Transactions on Sustainable Energy","volume":"15 4","pages":"2310-2321"},"PeriodicalIF":8.6,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141943729","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}

Depending on the choice of synchronization methods, grid-connected converters may exhibit distinct nonlinear behavior that plays a vital role in determining their transient stability. Recently, the grid-voltage-modulated direct power control (DPC) has been proposed as an alternative to the conventional phase-locked loop (PLL) to enhance the dynamic response of the grid-following converter (GFLC). However, existing studies have primarily treated the DPC-based GFLC as a linear system. In this paper, we investigate the nonlinear behavior of this converter under weak grids using a large-signal model based on double reference frames. Our findings reveal that the DPC-based GFLC demonstrates sustained oscillation. Interestingly, the stable periodic orbit observed does not arise from a Hopf bifurcation but rather a saddle-node bifurcation of periodic orbits. This critical bifurcation is characterized by the coexistence of a stable periodic orbit and a stable equilibrium point, resulting in a sudden contraction of the converter's stability region. Furthermore, we provide a comparison between the nonlinear behavior of PLL-based GFLCs and DPC-based GFLCs. To validate our findings, we present full-circuit simulations and laboratory experiments.","PeriodicalId":452,"journal":{"name":"IEEE Transactions on Sustainable Energy","volume":"15 4","pages":"2287-2298"},"PeriodicalIF":8.6,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141943728","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}

Prior WT knowledge is utilized by establishing a spatially structured directed graph embedded in a graph attention network (GAT). The features in WTs’ supervisory control and data acquisition system are indicated by the nodes in GAT. Then, the global and local attention embedding layers as well as long short-term memory layers are employed to combine spatio-temporal information from each node. Finally, the condition monitoring in WTs’ graph and node-level are established, and a fault propagation chain at node-level is constructed for explaining condition monitoring results. To demonstrate the explainability, robustness and sensitivity of the proposed approach, a comparative analysis between a true fault case and a false alarm case are given, and anomaly detection results are also reported.","PeriodicalId":452,"journal":{"name":"IEEE Transactions on Sustainable Energy","volume":"15 4","pages":"2276-2286"},"PeriodicalIF":8.6,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141943733","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}

In the latter, immediate or intra-stage cost functions (ICF or ISCF) have been proposed in the literature to provide thermal generation costs for each weekly/monthly stage, to address the uncertainty and high variability of RES without explicitly discretizing the stage in hourly steps. This work proposes a combined two-stage Benders decomposition and dual dynamic programming (DDP) approach to improve the construction and consideration of such ISCF for the MLTP problem. In this case, a set of subproblems considering hourly aspects as load curve, RES intermittency and peak capacity of hydro-generation are iteratively solved in the DDP master problem of each stage, for several scenarios of RES generation profiles, along DDP iterations. Since the discretization points of the ISCF are obtained on demand, this approach yields more accurate ISCF functions, specially in multi-area systems. The methodology is validated for both a tutorial case and a case based on data from the large-scale Brazilian system, where more realistic mid-term policies are obtained when compared to current approaches, with a reduced number of subproblems.","PeriodicalId":452,"journal":{"name":"IEEE Transactions on Sustainable Energy","volume":"15 4","pages":"2263-2275"},"PeriodicalIF":8.6,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141943730","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}

Their aggregated effects alter the dynamic characteristics of the active distribution network (ADN). However, the typical model of ADNs does not consider the transient characteristics of IBDGs, leading to an inaccurate characterization of the dynamic characteristics of ADNs. This paper proposes an ADN equivalent model that considers the transient characteristics of IBDGs. Firstly, the detailed ADN model with IBDGs and the corresponding typical model are constructed, and the effect of IBDG on the accuracy of the equivalent model under large disturbances is analyzed. To characterize the transient behavior of IBDGs, the Low-Voltage-Ride-Through (LVRT) exit time is introduced. Subsequently, the AGglomerative NESting (AGNES) algorithm is used to cluster IBDGs within ADN based on their LVRT exit times. The determination of several clusters is based on multiple evaluation indexes. Then, a parameterization method is given for an ADN equivalent model structure applicable to IBDG grouping. Finally, the effectiveness of the proposed model is demonstrated by constructing practical engineering. Simulation results illustrate that the proposed model accurately reflects the transient characteristics of ADN and maintains high accuracy under different operating conditions.","PeriodicalId":452,"journal":{"name":"IEEE Transactions on Sustainable Energy","volume":"15 4","pages":"2249-2262"},"PeriodicalIF":8.6,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141969361","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, operating an IES smoothly is difficult due to source–load fluctuations and the complexity of the multiple timescales of different energy flows. To tackle the challenges, this paper proposes a two-stage dual-loop optimization framework for IESs, where the two stages comprise the first stage: day-ahead cooperative optimization of source-storage-demand (DCOS), and the second stage: intraday dual-loop rolling optimization control (IDRO). In DCOS, energy storage, and integrated demand response models are established, and a carbon emission trading mechanism is introduced to achieve an economically low-carbon operating plan. In IDRO, an electric power rolling optimization model based on model predictive control is established in the inner loop, and a cooling and heating power output adjustment strategy based on user comfort event-trigger mechanism is developed in the outer loop. The proposed optimization strategy enables the coordinated operation of multiple energy flows across various time scales, effectively mitigating the imbalance between production and demand during intraday operations under source–load fluctuations scenario. In case studies, this strategy is applied to a typical IES, with simulations conducted to evaluate its performance during typical summer and winter seasons.","PeriodicalId":452,"journal":{"name":"IEEE Transactions on Sustainable Energy","volume":"15 4","pages":"2234-2248"},"PeriodicalIF":8.6,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141943738","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}

This phenomenon could induce abnormal operations in high-precision equipment or result in erroneous computer memory functions. To handle this issue, this paper proposes a voltage control to smooth out a critical bus voltage, without utilizing the local controllable devices, while maintaining the bus voltages across the distribution system within the allowable range. First, a smoothing out control of voltage is proposed and theoretically proved to mitigate the voltage fluctuations at the critical bus by the first-order inertia. Second, an optimization model is proposed for the coordinated voltage control, which coordinates the actions of discrete control devices with the smoothing out control of PV inverters. A novel convex approximation method is proposed to transform the nonconvex model into an approximate convex model. It is theoretically proved that the solutions obtained by solving the approximation model can control the bus voltages across the distribution system within the allowable range. Last, the proposed voltage control is simulated in 15-bus and 51-bus distribution systems. The 6-minute and 24-hour simulations show that a single voltage fluctuation and the sum of squared voltage fluctuations at a critical bus are reduced by 22.4% and 36.5%, respectively, as compared to the results offered by using the existing benchmark control method.","PeriodicalId":452,"journal":{"name":"IEEE Transactions on Sustainable Energy","volume":"15 3","pages":"2038-2049"},"PeriodicalIF":8.6,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140800635","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}

Unlike existing approaches, the proposed approach analytically establishes voltage stability constraints and incorporates them into droop slope optimization for local controllers, mitigating voltage oscillation risks. Additionally, a novel deviation-aware optimization method is developed to calculate optimal voltage references. This method treats the deviations between fixed-point voltages and their references as uncertainties and accounts for their impacts on voltage security through chance-constrained programming.
