Optimizing CHP-based multi-carrier energy networks with advanced energy storage solutions.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This paper presents an advanced operational framework for large-scale combined heat and power (CHP)-based multi-carrier energy (MCE) networks integrating both electrical and gas energy storage systems (EESS and GESS). A novel coordinated controller is developed to regulate energy flows by managing charging and discharging cycles of storage units while stabilizing electricity and gas supply to CHP units. The operational optimization problem is solved using a parameter-free Teaching-Learning-Based Optimization (TLBO) algorithm, which efficiently minimizes total costs and enhances system flexibility. The proposed approach is validated on a comprehensive testbed comprising the IEEE 14-bus power system, the Belgian natural gas network, and district heating subsystems. Results showed that the presence of EESS reduced the total operation cost of the network by about 0.075%, while the use of GESS increased the operation cost by about 0.024%. Overall, the framework significantly improves operational cost efficiency, energy flow stability, and network resilience compared to existing methods. This work provides valuable insights into the integration and coordinated control of multi-energy storage in CHP-based MCE networks, contributing to the development of more sustainable and flexible energy systems.
