Abstract New energy can enhance the load capacity of distribution networks, and addition storage suppress fluctuations caused by uncertainty new energy, promoting stable absorption networks. This paper explored impact integration into network load‐carrying proposed a method for evaluating networks improving GA‐BWO with voltage adaptive control. Under premise considering access to increase on status is derived. Constructing evaluation indicator system safety, flexibility, economy, then calculating weights using AHP‐EWM building function. Building carrying model based objective function constraint conditions this basis, utilizing bus adaptively control balance factor development stage Beluga algorithm, introducing mutation process Genetic realize solution capacity. Evaluate storage, example, prove improvement effect output characteristics provide theoretical basis regional planning construction.

ABSTRACT Smart local energy systems (SLESs) are central to enhancing localization and decentralization of the sector. Although these widely studied in literature, Nordic conditions probabilistic approaches have remained out spotlight. This study analyzes economically optimized configurations for a SLES. We define cost levels at which various technologies become feasible invest in. also evaluate life cycle emission reductions achievable from systems. Our case utilizes Monte Carlo optimization with integrated economic models. The results 2000 cost‐optimized SLES years 2020–2023 indicated that compared baseline, levelized electricity reduced 98% cases, while specific greenhouse gas emissions 97% cases. mean positive carbon handprint was 44%. Maximum costs deploy were 30 €/MWh wind power, 500 €/kW solar 120 €/kWh battery storage. Thermal storage commonly utilized. outcomes highlight importance sector integration context SLESs, as cases achieved large especially heat carrier. indicate SLESs could be viable mitigation.

In this paper, we present an optimization planning method for enhancing power quality in integrated energy systems large-building microgrids by adjusting the sizing and deployment of hybrid storage systems. These incorporate wind solar power, natural gas supply, interactions with electric vehicles main grid. developed, objectives cost-effective low-carbon operation, lifecycle cost storage, improvements, renewable utilization are targeted coordinated using utility fusion theory. Our addresses multiple forms—cooling, heating, electricity, gas, energies—which through a combined cooling, system turbine. The incorporates batteries compressed-air to handle fast slow variations demand, respectively. A sensitivity matrix between output sources voltage is modeled flow DistFlow, reflecting improvements respective constraints. proposed validated simulating various typical scenarios on modified IEEE 13-node distribution network topology. novelty paper lies its focus application within large buildings approach dimensions, including making co-location capacity decisions. Other innovative aspects include coordination combinations, simultaneous siting decisions, calculations, enhancement. As part these design considerations, microgrid-related technologies cutting-edge nearly zero-energy building designs, representing pioneering attempt field. results indicate that multi-objective, multi-dimensional, fusion-based significantly enhances economic efficiency operation building-level planning.

Abstract Long‐term hydrogen storage systems are considered a solution to the long‐term supply imbalance caused by different seasonal characteristics in renewable energy output and load. However, most existing planning models assume whole year‐round net load series is known advance optimal operation sequence of derived accordingly. This assumption underestimates necessary capacity because difficulty accurate fine‐grained forecasting. work proposes framework that robust fluctuation. The daily average component from historical first formulate scenario set. On this basis, model developed where trend forced be identical for all scenarios not respond one specific with full information sequence. results show given proposed more real‐time less shedding.
