The use of transient energy storage systems (TESSs) has proven to be an effective solution to this issue. Hence, it is crucial to understand the impact of TESS components design on sizing the power-train system during fast frequency response. While power-train systems have been extensively discussed, the impact of dc-link voltage on the TESS power-* train and associated power electronics specification requirements has not been evaluated. This study uses a sodium-nickel chloride (NaNiCl2) battery-based TESS to assess different power-train options. Specifically, the research investigates the impact of variations in dc-link voltage due to battery regulation and state-of-charge (SoC) on the design of the TESS-connected power-train system, since these will be the major contributions to the power-train system performance envelope. This paper also compares the performance of TESS power-train systems with four different schemes. The power-train models include the detailed modelling of energy sources, power electronic converters, and transformers based on published parameters and testing data. Additionally, the study proposes a performance index to evaluate the superiority of the four schemes in terms of voltage and current rating, efficiency and battery size.","PeriodicalId":55000,"journal":{"name":"IET Renewable Power Generation","volume":"18 S1","pages":"4679-4688"},"PeriodicalIF":2.6,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rpg2.13175","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143248363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a first-of-its-kind comprehensive analysis of 17 illustrative pathways varying the impact of e-fuel imports, grid interconnections and an accelerated energy transition towards the Caribbean's carbon neutrality by 2050. The research method is based on techno-economic principles for designing a cost-optimal energy system. An optimisation tool is used, the LUT Energy System Transition Model, to analyse the various pathways. The study finds that high uptake of renewables in Caribbean energy systems significantly lowers costs and enhances reliability, crucial for building competitive and resilient economies. Renewable energy dominated pathways show 7–24% lower cumulative costs compared to alternatives, with grid integration reducing costs by 1–10%. Accelerated transition pathways incur 3–12% higher costs than complete defossilisation by 2050. Solar photovoltaics, wind power, batteries, and electrolysers are pivotal for achieving carbon neutrality by 2050. Importing e-fuels reduces system costs by 7–16% and supports local resource use. Offshore renewable energy overcome land limitations, driving sustainable development and a vibrant blue economy. High electrification levels with renewable energy, sector coupling, and Power-to-X solutions enhance system efficiency and flexibility. Given the dominance of solar photovoltaics, the Caribbean's energy transition could be more appropriately called a ‘Solar-to-X Economy’. This research contributes to the international perspective on sustainable energy transition for islands.","PeriodicalId":55000,"journal":{"name":"IET Renewable Power Generation","volume":"18 S1","pages":"4650-4678"},"PeriodicalIF":2.6,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rpg2.13173","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143248364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This trend results in the decline of system inertia and thus raises the frequency secure issue. Concurrently, electric vehicles (EVs) proliferate. Numerous EVs hold a huge potential of frequency regulation in case of contingency as EVs are able to achieve primary frequency responses (PFRs) via vehicle to grid chargers. However, the value of frequency responses from aggregated EVs has not fully exploited. This paper, proposes a chance constrained scheduling model incorporating the ability of PFRs from aggregated EVs. The proposed model characterizes uncertainties associated PFR capacities from aggregated EVs and wind power forecast errors by the Wasserstein-metric ambiguity sets, which do not rely on distributional assumption, and then formulates uncertainties-related constraints as distributionally robust (DR) chance constraints. These DR chance constraints are reformulated as tractable linear programs. Consequently, the proposed model leads to a mixed-integer linear program. Numerical results on a modified IEEE 39-bus system show that incorporating PFR from EVs can reduce total costs from $4,540,396 to $4,431,233, which is reduced by 2.4%. The proposed model also achieves better reliability compared to traditional methods, demonstrating the distributionally robust optimization in enhancing electricity scheduling and rising renewable integration.","PeriodicalId":55000,"journal":{"name":"IET Renewable Power Generation","volume":"18 S1","pages":"4348-4359"},"PeriodicalIF":2.6,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rpg2.13171","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143248220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Central to this approach is the localized autonomous controller with a socket protocol interfaced communication layer, dynamically managing operations based on real-time conditions such as generation, load, and battery state of charge. By integrating battery storage systems, the strategy reduces diesel generator dependency during grid outages. Comprehensive simulations and controller hardware-in-the-loop testing validate its effectiveness, demonstrating improved stability and decreased reliance on diesel generators.

To counter this, a virtual inertia and damping controller utilizing battery energy storage, leveraging the virtual synchronous generator concept is proposed in this paper. This controller supplements inertia by modulating active power flow, thus stabilizing frequency during high renewable energy source penetration periods. Additionally, to enhance load frequency control, a cascaded controller combining adaptive neuro-fuzzy inference system-assisted fractional-order PID with a nonlinear FOPI controller is introduced. It should be noted that improper controller parameters can worsen frequency deviations and system stability. Hence, a whale optimization algorithm optimizes control parameters using the integral time absolute error based objective function. Simulation studies on a modified IEEE 10-generator 39-bus power system, considering various disturbances like stochastic load-generation, nonlinear generation behaviours, and time delay, validate the effectiveness of the proposed controller. Comparative analysis demonstrates the superior resilience of the cascaded control approach in managing contingencies within low-inertia power systems, with a remarkable performance improvement of 87.9811% compared to existing control methods.","PeriodicalId":55000,"journal":{"name":"IET Renewable Power Generation","volume":"18 S1","pages":"4602-4620"},"PeriodicalIF":2.6,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rpg2.13169","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143244045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To design and evaluate controllers, wind farm flow models are used that capture the key aerodynamics of the system whilst remaining computationally efficient for iterative controller design. This review article reveals considerable heterogeneity in the potential wind farm flow models to study WFFC. Lack of consensus is problematic as differences in results from separate studies are attributable to both controller and model effects, making it hard to draw comparative conclusions. Hence, an expert elicitation is completed surveying WFFC practitioners. Two key contributions are presented. First, a guide to available software for WFFC, which, combined with results from an expert elicitation on flow model requirements, facilitates selection of suitable software for investigating WFFC problems. Secondly, critical future research areas are identified. Research into high fidelity wind direction models (particularly transient effects) and wake meandering models for fatigue load investigations are identified as critical to the field. A lack of consensus regarding the importance of atmospheric boundary layer effects, wake induced turbulence, and lateral wind correlation identifies the requirement of sensitivity studies in these areas.","PeriodicalId":55000,"journal":{"name":"IET Renewable Power Generation","volume":"18 S1","pages":"4707-4725"},"PeriodicalIF":2.6,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rpg2.13149","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143253752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, coordinating the upstream energy sources, internal energy stations, distribution networks, and downstream loads within the PIES framework remains a challenge. Developing a station-network coordinated planning scheme for PIES confronts challenges, such as overly complex models that are difficult to solve and the difficulty of implementing standard methods for medium and long-term planning. This paper proposes a multi-stage coordinated planning approach for PIES, containing energy stations, multi-energy networks, and load aggregation nodes. The energy equipment and energy networks are precisely modelled to enhance the reliability of the planning scheme. The chance-constrained programming (CCP) method is adopted to address uncertainties arising from renewable energy generation. Additionally, the improved big-M method and second-order cone (SOC) relaxation technique are utilized to manage non-linear elements, transforming the model into a mixed-integer second-order cone programming (MISOCP) form to enhance solution efficiency. A case study illustrates that the proposed method enables effective allocation of equipment and networks, outperforming single-stage planning by reducing investment costs, enhancing facility utilization rates, and facilitating renewable energy integration.","PeriodicalId":55000,"journal":{"name":"IET Renewable Power Generation","volume":"18 S1","pages":"4543-4564"},"PeriodicalIF":2.6,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rpg2.13166","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143253678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Differently, in the power-electronic-dominated power system (PEDPS), the dynamics of transmission lines of network for fully differential equations should be considered, due to the rapid response of converters' controls, for example, the alternating current controls. This poses a great challenge for the cognition, modeling, and analysis of the PEDPS. In this article, a nonlinear DAE model framework for the PEDPS is established with differential equations for the source nodes and algebraic equations for the dynamical electrical network, by generalizing the application scenarios of Kron reduction. The internal and terminal voltages of source nodes of converters are chosen as ports of nodes and network. Namely, the internal and terminal voltages of source nodes work as their output and input, respectively, whereas they work as the input and output of the algebraic network, respectively. The impact of dynamical network becomes clear, namely, it serves as a (linear) voltage divider and generates the terminal voltage based on the internal voltage of the sources simultaneously. By keeping only useful independent state variables, all differential equations for the transmission lines can be transferred to algebraic equations. With this simple model, the roles of both nodes and network become apparent, and it enhances the understanding of the PEDPS dynamics. On the other hand, broad simulations are conducted and compared to verify the proposed DAE framework for the PEDPS. As all independent variables have been kept in the model, it is found that they show the same computational accuracy, but better efficiency in computational time, compared to the electromagnetic-transient simulation results.","PeriodicalId":55000,"journal":{"name":"IET Renewable Power Generation","volume":"18 S1","pages":"4519-4529"},"PeriodicalIF":2.6,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rpg2.13164","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143253211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
