However, the interest coordination of different stakeholders with privacy preservation is challenging. Therefore, the heterogeneous-agent coordinated secure and contribution-aware equilibrium strategy for IEGS with a fully decentralized approach is proposed. The flexible operation of PDS, NGS, and community-integrated energy stations (CIESs) enables bidirectional power interaction between PDS and NGS, enhancing the security of IEGS. This interaction is optimized by integrating diverse demand responses, including interruptible, transferrable, and replaceable loads, to ensure more effective power exchanges. A contribution-aware asymmetric Nash bargaining method is proposed for revenue allocation, determined by the stakeholder contribution degrees calculated through a nonlinear energy sharing mapping method. Additionally, the study employs the adaptive alternating direction method of multipliers (ADMM) to resolve the coordinated secure operation challenges and contribution-aware equilibrium issues among heterogeneous agents, thereby achieving full decentralization of stakeholder collaboration with ensured privacy and operational independence. A numerical study on a modified IEEE 33-bus PDS and 9-node NGS, connecting 2 CIESs, proves the strategy’s efficacy. The proposed strategy boosts voltage by 60.96 % and pressure by 93.33 %. The profit rates of cost for PDS, NGS, CIES1, and CIES2 surge to 198.69 %, 112.55 %, 26.44 %, and 25.78 %.</div></div>","PeriodicalId":56142,"journal":{"name":"Sustainable Energy Grids & Networks","volume":"42 ","pages":"Article 101691"},"PeriodicalIF":4.8,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143715261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a new method to accelerate DSSR calculation. Firstly, the DSSR models are briefly introduced. Secondly, the influence mechanism of the main transformer capacity on the DSSR is observed and analyzed, forming the theoretical basis for simplifying the computation. Thirdly, a speed-up method based on neglecting the main transformer constraints is proposed. The method includes the calculation formula of the main transformer active capacity, forming main transformer active capacities for common distribution systems in China, and a convenient lookup table-based speed-up process. When the main transformer reaches or exceeds this active capacity condition, it is determined that the main transformer constraints can be ignored in the DSSR modeling, thereby simplifying the model and improving calculation speed. Finally, the proposed method is verified by an extended IEEE-RTBS-BUS4 case and a real distribution system case. The proposed method can accelerate the DSSR calculation by 701 times when it is individually used. The method is further integrated with another method, which combines two speed-up methods for the first time. As a result, the solving efficiency is improved by 6.02 times and 7.43 times, respectively, compared to using the two methods individually, which has achieved the best speed-up effect so far. This study finds that common distribution systems in China mostly satisfy the speed-up condition.</div></div>","PeriodicalId":56142,"journal":{"name":"Sustainable Energy Grids & Networks","volume":"42 ","pages":"Article 101688"},"PeriodicalIF":4.8,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although this problem can be formulated as a mixed integer nonlinear program, solving the resulting optimization problem requires significant time and resources. A carefully selected initial solution, which can be identified by appropriate heuristics, reduces the search space, accelerates convergence, and ensures feasibility. This paper introduces two heuristic algorithms based on the Alternating Direction Method of Multipliers (ADMM) to address this problem. These heuristics break down the problem into smaller, more manageable subproblems that can be solved efficiently. Two algorithms are developed: one relies on natural variable substitution, and the other on a previously used relaxation technique. The challenge encountered in previous studies of incorporating radial constraints with ADMM is addressed by redefining the combinatorial subproblem in the projection step of ADMM as a minimum weight rooted arborescence problem, whose solutions are guaranteed to be radial. Convex optimization techniques can then handle the remaining subproblems. The performance of both heuristics is evaluated through numerical experiments on the 33-bus and 70-bus systems, as well as on a real-world electrical network.</div></div>","PeriodicalId":56142,"journal":{"name":"Sustainable Energy Grids & Networks","volume":"42 ","pages":"Article 101684"},"PeriodicalIF":4.8,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current optimization methods for hybrid electric vehicles (HEV) in multi-traffic-light scenarios still have room to improve energy-saving optimality and computational efficiency. Hence, this paper proposes a two-layer convex approach for the eco-driving of connected HEVs at signalized intersections. In the upper layer, a convex motor-power model is built, and a position constraint within the green-light time window is decided using traffic light information and signal phase-and-timing data. Then, a convex velocity-planning problem to minimize motor energy consumption is formulated and efficiently solved. In the lower layer, the engine's optimal operating line and unified battery-power constraints are introduced, and a series of convexification steps are performed. This enables the establishment of a convex-optimization energy management problem for minimizing fuel consumption, facilitating fast solution. Results show that the proposed method can effectively manage multi-signal scenarios, allowing vehicles to pass through green lights and avoid red-light waits. Regarding motor energy and fuel consumption, it achieves near-optimal results, with a deviation of less than 2 % from the global optimum.

However, conventional research often overlooks the impact of multiple extreme weather conditions and only considers planning for one specific type of extreme weather. This paper proposes a resilience-oriented distributed generation planning approach for distribution networks, which takes into account multiple extreme weather conditions. Firstly, a line fault probability model is established to capture the impact of typhoons, rainstorms, ice and snow weather. Secondly, a fault scenario generation and simplification method based on modified monte carlo simulation and <em>k</em>-means clustering is proposed to ensure the representativeness and computational efficiency of the selected scenarios. Additionally, a two-stage stochastic mixed integer programming model is introduced to enhance system resilience through distributed generation configuration and network topology reconstruction. The first stage focuses on determining the number, location, and size of distributed generation with economic objectives, while the second stage addresses the recovery method after an uncertain extreme event based on the distributed generation configuration obtained in the first stage. The proposed model is applied to modified IEEE 33-bus system and IEEE 123-bus system.

The results show evidence of fat tail distributions for some consumers. For both consumer groups, extreme values scale as an inverse power law with aggregation over increasing numbers of consumers and as a decaying exponential with the timescale of moving-average smoothing.
