Abstract

The intermittent nature of solar energy results in a generation–load mismatch, posing a significant challenge to reliable power utilization. Battery Energy Storage Systems (BESS) play a crucial role in mitigating this issue. However, effective operation requires advanced control strategies. Conventional techniques, such as classical Maximum Power Point Tracking based on Constant Current/Constant Voltage, often struggle to cope with the nonlinear dynamics of PV–BESS systems, leading to reduced efficiency and accelerated battery degradation. This paper proposes a hybrid adaptive control strategy integrating fuzzy logic decision-making, Genetic Algorithm (GA) optimization, and Extended Kalman Filter (EKF)-based State of Charge (SoC) estimation. A comprehensive PV–BESS model is developed in the MATLAB/Simulink environment using real solar irradiance and realistic load profiles. Simulation results demonstrate an absolute improvement in energy efficiency of approximately 14.3%, a SoC estimation accuracy within ±5%, and an extension of battery lifetime by 18–25% compared to conventional control methods. The proposed approach offers a robust and computationally efficient solution for PV–BESS operation, making it suitable for future microgrid and renewable energy storage applications.

Abstract

Manajemen mobilitas merupakan tantangan utama dalam jaringan seluler nirkabel akibat dinamika kanal dan mobilitas pengguna, di mana skema handover konvensional berbasis ambang RSS atau SINR sering memicu handover tidak perlu dan efek ping-pong. Penelitian ini mengusulkan mekanisme keputusan handover cerdas berbasis kecerdasan buatan menggunakan Support Vector Machine (SVM) dengan integrasi fitur RSS, SINR, kecepatan pengguna, dan beban base station. Evaluasi melalui simulasi MATLAB pada kondisi kanal dan mobilitas yang realistis menunjukkan bahwa pendekatan yang diusulkan mampu mengurangi jumlah handover dan kejadian ping-pong lebih dari 50%, menurunkan probabilitas packet loss sekitar 6%, serta meningkatkan effective throughput sekitar 6% dibandingkan dengan skema berbasis threshold konvensional. Hasil ini menegaskan kontribusi ilmiah utama penelitian dalam merumuskan dan mengevaluasi mekanisme keputusan handover berbasis SVM yang mengintegrasikan parameter kanal dan mobilitas secara simultan, serta secara kuantitatif menunjukkan peningkatan kinerja jaringan dibandingkan dengan skema handover berbasis threshold konvensional.

Abstract

Data continuity problems in environmental monitoring systems due to congestion in communication traffic, interference from wireless communications, and failure of components present a great problem in maintaining accurate and reliable data continuity and environment assessment results. This paper proposes the development of a simulation framework for evaluating the reliability and data continuity of the distributed IoT-based environmental quality monitoring system with different traffic intensities, wireless communication interference levels, and component failures. The reliability performance measures include: data delivery ratio (DDR), packet loss ratio (PLR), transmission delays, system availability, time in interruption state and data continuity ratio (DCR). Based on simulation analysis, the proposed distributed IoT environmental monitoring system has DDR and DCR of 0.971 when the network is under baseline operations. Under high traffic intensity, DDR was reduced to 0.734 while under high traffic and high interference conditions, DDR is reduced to 0.420 while PLR was 0.580. Under gateway component failure, DDR was reduced to 0.409 while under high traffic, high interference, and component failure condition, DCR was 0.487 or a 49.8% reduction from baseline. The recovery techniques have helped significantly increase the availability of the system when the environment is degraded. This indicates that the main factors that determine the reliability of IoT-enabled environmental monitoring systems are gateway resilience and communication efficiency.
