Abstract

Power quality is paramount for ensuring reliable, stable, and environmentally sustainable electricity supply from distributed renewable energy sources (DRESs). However, conventional controllers in hybrid Photovoltaic–Electric Vehicle Battery (PV–EVB) systems typically suffer from limitations such as steady-state error, harmonic distortion, suboptimal transient response, and voltage overshoot. Addressing these issues, this paper proposes a novel arithmetic optimization algorithm (AOA) to enhance performance and power quality in PV–EVB systems subject to load and environmental variability. The proposed methodology consists of two primary components. First, an AOA-based global maximum power point tracking (GMPPT) controller dynamically adjusts PV output to suppress upward frequency oscillations. Second, AOA is employed to optimize the proportional-integral (PI) controller gains for both the bidirectional DC/DC converter and the single-phase inverter of the EVB system, thereby reducing downward frequency fluctuations. These coordinated strategies effectively stabilize DC link voltage (DLV), control grid frequency, and minimize total harmonic distortion (THD) in the grid current. Quantitative results demonstrate that, AOA-based approach achieves a rapid settling time of 0.3 s, low overshoot (3%), and minimal steady-state error (0.2%), while maintaining high PV power and system efficiency (99%). Thus, the AOA-based control strategy significantly improves the grid-integration of hybrid PV–EVB systems and supports more robust, efficient, and sustainable energy infrastructure.
基于性能改进和功率管理的光伏电池并网系统算法优化
电能质量对于确保分布式可再生能源(DRESs)的可靠、稳定和环境可持续供电至关重要。然而,混合光伏-电动汽车电池(PV-EVB)系统中的传统控制器通常存在稳态误差、谐波失真、次优瞬态响应和电压超调等局限性。针对这些问题,本文提出了一种新的算法优化算法(AOA),以提高受负载和环境变化影响的PV-EVB系统的性能和电能质量。拟议的方法包括两个主要部分。首先,基于全局最大功率点跟踪(GMPPT)控制器动态调整PV输出以抑制频率向上振荡。其次,利用AOA优化双向DC/DC变换器和EVB系统单相逆变器的比例积分(PI)控制器增益,从而减小向下的频率波动。这些协调策略有效地稳定了直流链路电压(DLV),控制了电网频率,并降低了电网电流中的总谐波失真(THD)。定量结果表明,基于aoa的方法在保持高光伏功率和系统效率(99%)的同时,实现了0.3 s的快速稳定时间、低超调量(3%)和最小稳态误差(0.2%)。因此,基于aoa的控制策略显著改善了混合PV-EVB系统的电网集成,并支持更强大、高效和可持续的能源基础设施。

期刊介绍: The impact of computers has nowhere been more revolutionary than in electrical engineering. The design, analysis, and operation of electrical and electronic systems are now dominated by computers, a transformation that has been motivated by the natural ease of interface between computers and electrical systems, and the promise of spectacular improvements in speed and efficiency. Published since 1973, Computers & Electrical Engineering provides rapid publication of topical research into the integration of computer technology and computational techniques with electrical and electronic systems. The journal publishes papers featuring novel implementations of computers and computational techniques in areas like signal and image processing, high-performance computing, parallel processing, and communications. Special attention will be paid to papers describing innovative architectures, algorithms, and software tools.
