Abstract
The increasing variety of energy conversion units and storage equipment connected to the multi-energy system, along with the uncertain factors posed by distributed wind and photovoltaic power generation, have made the energy flow structure of the system more complex. This complexity has created significant challenges for the frequency regulation of traditional energy hub systems. One of the characteristics of a microgrid (MG) is the use of combined heat and power (CHP) systems to generate both electrical and thermal energy at the same time. This can boost the system's dependability, efficiency, and economic performance. As a CHP's ramping capability makes it a useful tool for monitoring and controlling the MG's frequency, it will be employed in this research to achieve this goal. The complexity of the system's dynamics and set tasks throughout the course of the performance period necessitates advanced control structures for the MG with CHP systems. To address the challenges of controlling in MG with CHP systems, this research introduces a novel control structure based on deep reinforcement learning and single input interval type-2 fuzzy fractional-order proportional integral (SIT2-FFOPI) for this system. The SIT2-FFOPI serves as the main controller, with its fundamental parameters established through the utilization of the Improved Salp Swarm Algorithm (ISSA) optimization technique. An adaptive deep deterministic policy gradient (DDPG)-based actor-critic system has been developed to enhance the main controller's learning potential, thereby enabling it to more effectively address control challenges in the isolated MG. The efficacy of the suggested approach in real-time was evaluated through simulations carried out utilizing an OPAL-RT-based Hardware-in-the-Loop (HiL) configuration. As a result of this study, it was determined that the proposed controller for load disturbance, renewable energy sources (RES) power changes, and contingency circumstances in MG outperforms other controllers in terms of performance.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
