To address this issue, technology that accurately predicts PV power generation is essential. Therefore, we predicted total PV power generation for the next day in the Tokyo Electric Power Company (TEPCO) area. In this paper, we proposed a method that adds normalized images of variables forecasted from Meso-Scale Model (MSM) of Japan Meteorological Agency (JMA) and the average values of weather information indicating the characteristics of the area to the input of Autoencoder, and confirmed that prediction accuracy was improved. It was also shown that prediction accuracy could be further improved by adding daytime and solar altitude data. © 2026 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"21 9","pages":"1297-1303"},"PeriodicalIF":1.0,"publicationDate":"2026-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148696339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The strategy is based on scheduled charging and Vehicle-to- Grid (V2G) interaction. First, by analyzing power system characteristics at different levels, a multi-level power balance control framework is constructed. Next, a model of the scheduling potential of EVs participating in V2G within a distribution transformer supply zone is developed, and a scheduling strategy for charging and discharging is established. With the travel demands of users, the V2G power feedback, and the influence of time-of-use electricity pricing on the charging costs all taken into account, a multi-objective optimization scheduling strategy is designed to achieve power supply and demand balance in distribution transformer supply zones and reduced charging costs for users. Simulation results prove that the proposed strategy can effectively balance the power supply and demand within a distribution transformer supply zone, mitigate the load fluctuations caused by EV charging loads integration, reduce the charging costs and protect the financial interests of users participating in V2G interaction. © 2026 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"21 9","pages":"1351-1361"},"PeriodicalIF":1.0,"publicationDate":"2026-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148696445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the travel time of MEG in the transportation network will greatly affect the restoration speed of important loads, it is vital to take into account the routing problem of MEG in the transportation network when achieving MEG-assisted distribution network restoration. In this context, this paper proposes a two-stage restoration strategy considering pre-event MEG allocation and after-event restoration with real-time scheduling of MEG. Specifically, first, the spatial coupling mode of distribution network and transportation network is analyzed, and multiple fault scenarios are generated based on the fragility curves of distribution network equipment under extreme weather conditions. Second, aiming to optimize the MEG dispatching path and maximizing the load restoration after extreme events, a pre-event allocation model for MEGs is established. Then, focusing on the specific post-event distribution network fault scenario, a multi-period restoration model considering the real-time dispatching of MEG is established. The real-time routing and scheduling constraints of MEG in coupled distribution-transportation networks and the operation constraints of distribution network are fully incorporated. Eventually, case studies on the coupled PG&E69 distribution network and 30-node transportation network verify the effectiveness of the proposed restoration strategy. © 2026 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"21 9","pages":"1362-1371"},"PeriodicalIF":1.0,"publicationDate":"2026-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148696537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed topology adopts the design of partitioned-primary, where the armature windings and the slot PMs are arranged in the top primary, while the inset-type PMs are housed in the bottom primary. The excitation fields generated by the dual sets of PMs can be mutually superimposed in the air gap, significantly enhancing the thrust density of the machine. Meanwhile, the field windings integrated into the bottom primary enable flexible regulation of the resultant air gap flux, thereby extending the speed adjustment range of the machine. Firstly, the topology and operating principle are introduced. Then, based on 2D finite-element method (FEM), a global optimization is performed on both the proposed machine and an existing machine for comparison, targeting higher average thrust force, lower thrust ripple, and wider flux regulation range. Finally, the electromagnetic performance of the optimized machines is comparatively analyzed.

Battery energy storage systems (BESSs) are increasingly recognized as an effective solution for addressing these challenges and improving grid operations, especially under the management of grid operators. However, given the substantial investment and immobility of BESSs, determining their optimal placement and capacity while considering future PV-deployment uncertainties is crucial. Moreover, selecting locations that satisfy grid constraints and offer multifunctional contributions is desirable. One promising approach is to select sites where the voltage impact of battery charging and discharging is minimal, which is expected to enhance BESS flexibility in output regulation. Therefore, this paper considers multiple PV-deployment cases to simulate high PV penetration that induces grid congestion in distribution networks, and evaluates optimal BESS sites—selected from candidates satisfying operational constraints—based on voltage margins relative to the acceptable range. Additionally, the study examines the interplay between optimal BESS positioning, the distribution of load and PV systems, and overall power-flow dynamics. Numerical simulations using a rural feeder model from CREST 126-feeder model are used to quantitatively assess the impact of BESS sites on voltage margin while satisfying constrains. © 2025 The Author(s).

The expected matrix of electric distance between nodes is obtained by discretizing the characteristics of PV output probability distribution.

On this basis, an upper-layer scheduling method aiming at minimizing the operating cost of the ADN system is proposed, and day-ahead scheduling plans are developed for devices such as on-load tap changer (OLTC) and capacitor banks (CBs) in each cluster. At the lower layer, real-time operational data are utilized to develop cluster voltage control strategies with the goal of maximizing the tracking of day-ahead scheduling plans, ensuring the economic and safe operation of the ADN while compensating for the shortcomings caused by forecast errors.

In many existing applications, the interconnected microgrids need a central controller to realize the scheduling of generators, energy storage systems, and flexible loads. However, each microgrid belongs to different owners, rendering the centralized control inconvenient. Thus, a novel distributed method for solving the economic dispatch problem (EDP) of interconnected microgrids is proposed in this paper. First, the EDP is reformulated to incorporate a penalty, and decomposed to subproblems for the microgrids. Then, a penalty-based distributed economic dispatch method (PDED) is proposed accordingly for each microgrid to solve the entire problem in parallel. Rigorous theoretical analysis has been provided to guarantee the equivalence of reformulation and the convergence of PDED to optimal solutions.
