The authors develop an approach for the coordinated recovery of interdependent power and WDSs, which enhances the resilience of both infrastructures from an operational standpoint based on the optimised dispatch of existing power and water resources after an extreme weather event. The proposed model allocates the available resources in both power and WDSs—including solar generation, battery energy storage systems, water stored in tanks, and small pumped-storage hydropower—to minimise the energy and water demand curtailment. The proposed model is tested on the interconnection of IEEE 33-bus test power distribution system with a 16-node test WDS. Results for the test system show that, by coordinating the power and water operation during the recovery, the energy curtailment cost reduces by 8.9%, while the water curtailment cost is reduced by 33.5% from adequately allocating energy resources without negatively affecting the demand requirements during the restoration process, when compared to the uncoordinated approach where each infrastructure is operated independently.</p>","PeriodicalId":36490,"journal":{"name":"IET Smart Grid","volume":"7 6","pages":"760-775"},"PeriodicalIF":2.4,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/stg2.12175","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141338569","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}

The transactive energy (TE) concept inverts the centralised grid model by leveraging the evolution of consumers to prosumers to prosumagers. The principal TE market design challenge is transactive control—using market and pricing mechanisms to coordinate autonomous peer interactions, to optimally allocate power and incentivise peers. Peer attraction, incentivisation and retention are all critical for practical TE implementation along three adoption stages, starting from independent peer transactions with the centralised market; to decentralised peer coordination; towards distributed peer-to-peer trading. Addressing gaps in related scholarship, the authors investigate the economic positions of distinct peer roles in each adoption stage and two local pricing strategies. Using a real market dataset, trading decisions are simulated over a 1-year horizon at hourly granularity. Coordinated action achieves better transactive control for the community, with economic superiority over centralised and distributed mechanisms. Distinct peer incentives should equitably align with their contribution to market functionality, such as the value ascribed to prosumagers' flexibility in local pricing and the constrained bargaining power of prosumers in distributed bilateral negotiations.</p>","PeriodicalId":36490,"journal":{"name":"IET Smart Grid","volume":"7 5","pages":"672-694"},"PeriodicalIF":2.4,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/stg2.12166","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141341812","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}

In recent years, the smart grid concept has been dramatically developed in different applications, such as islands, shipboards, aircraft, microgrids and grid integration of renewables. With the wide application of ESS in smart grids, significant technical challenges remain along with the enhancement of smart grid operations and services. These challenges can be categorised as control of ESS, optimal operation, and energy management systems, optimal design of hybrid ESS, protection of ESS, and power electronics for ESS connections. This necessitates suitable design and control of the interfaces between ESSs in smart grids, as well as consideration of different applications of smart grid systems. This special issue of IET smart grid is focused on research ideas, articles, and experimental studies related to ‘Energy Storage for Green Transition of Electrical Grids’ from contributors in universities, industries, and research laboratories to develop and propose novel solutions on applications of ESS in smart grids.&lt;/p&gt;&lt;p&gt;This special issue presents six papers providing some methodologies within the field of ongoing research and development, all of which were selected after undergoing a thorough peer-review process. Below, we expand the publications on this special issue. Some common themes within the papers on this special issue include control of hybrid storage systems, energy management of electric vehicles (EVs), photovoltaics (PV), and ESS, and voltage regulation of storage systems. All of these attributes are vitally important to the integration of energy storage for the green transition of power grids.

The actual parameters are updated by MFO and then sent to the MPC to minimise the model mismatches. The advantages of the proposed method, in terms of accuracy and convergence speed, are verified by comparison with Grey Wolf optimization (GWO) and particle swarm optimization (PSO).

The communication traffic of a VPP fundamentally indicates its activeness in interacting with the power system, thus providing a new dimension in depicting the behaviour characteristics of distributed energy resources in VPPs. Therefore, the prediction of communication traffic is significant in improving the control efficiency of VPPs. However, due to the involvement of numerous interactive agents characterised by both individual randomness and coordinative characteristics, traditional prediction models are no longer capable of fitting VPP communication traffic effectively. Therefore, a  novel prediction model is introduced that enhances the prediction accuracy by integrating long short-term memory (LSTM) and variational mode decomposition (VMD). This model employs VMD as the initial step for extracting the intrinsic modes from the traffic sequence, thereby mitigating the impact of incidental noise. Then, LSTM is applied to fit each intrinsic mode individually. Additionally, considering the outer influencing factors, the attention mechanism is incorporated.

An integrated energy system, which is interconnected with various energy resources and highly aggregated with groups of residential, commercial, and/or industrial buildings, is becoming the primary target for low-carbon transition due to its large energy consumption and high carbon emission density. The decarbonisation of integrated energy systems is of great significance in achieving the goal of carbon neutrality. The integrated energy system generally provides ideas for integrating multiple elements of the urban energy system, such as electricity, natural gas, heat networks, as well as residential, commercial, industrial or associated service systems and transportation, which makes the mechanism and method of decarbonisation more difficult and complicated. Meanwhile, digital technologies such as IoT, ICT, machine learning, and big data are drawing much attention as they can aid the decarbonisation process. With these novel technologies' promotion, the improvement will be made in terms of economy, energy efficiency and environmental benefit when developing an integrated energy system towards low-carbon/zero-carbon.&lt;/p&gt;&lt;p&gt;This IET Smart Grid special issue on Planning and Operation of Integrated Energy Systems for Decarbonisation invites a broad spectrum of contributors from universities, industry, research laboratories, and policymakers to develop and present novel solutions and technologies that will facilitate and advance the agenda of deep decarbonisation of integrated energy systems.&lt;/p&gt;&lt;p&gt;This special issue solicits original research papers that target at, but are not restricted to, the following aspects.
