Abstract

Accurate and reliable parameter estimation plays a pivotal part in the design of solar PV systems. However, the current PV parameter estimation (PVPE) methods still face great challenges due to the complicated characteristics of the PV models. In this paper, a novel meta-heuristic algorithm called improved simultaneous heat transfer search (ISHTS) is proposed to solve various PVPE problems. In ISHTS, two efficient strategies are embedded into the heat transfer search algorithm to improve the search performance. First, a simultaneous heat transfer strategy is adopted to diverse search equations for each generation to ameliorate the global detection. Second, a novel elitist perturbation strategy with adaptive perturbation amplitude is employed to enhance the local exploitation. The proposed ISHTS is applied to solve different PVPE problems including single diode, double diode, three diode and PV module. The performance of ISHTS is extensively compared with several state-of-the-art PVPE methods. Simulation results demonstrate that ISHTS achieves root-mean-square error (RSME) as low as \(9.8602 \times 10^{-4}\), \(9.8248 \times 10^{-4}\), \(9.8248 \times 10^{-4}\) and \(2.4251 \times 10^{-3}\), and obtains standard deviation (SD) as small as \(8.88 \times 10^{-17}\), \(2.05 \times 10^{-6}\), \(1.88 \times 10^{-5}\) and \(3.40 \times 10^{-17}\) for four different PV models, respectively. Based on the simulation results, ISHTS has advantages in terms of solution accuracy, reliability and convergence for various PVPE problems.

利用改进的同步传热搜索算法估算各种光伏电池和组件的参数
准确可靠的参数估计在太阳能光伏系统的设计中起着举足轻重的作用。然而,由于光伏模型的复杂特性,目前的光伏参数估计(PVPE)方法仍面临巨大挑战。本文提出了一种名为改进同步传热搜索(ISHTS)的新型元启发式算法,用于解决各种 PVPE 问题。在 ISHTS 中,两种高效策略被嵌入传热搜索算法,以提高搜索性能。首先,采用了同步热传递策略,为每一代的不同搜索方程改进了全局检测。其次,采用自适应扰动振幅的新型精英扰动策略来提高局部利用率。所提出的 ISHTS 被应用于解决不同的 PVPE 问题,包括单二极管、双二极管、三二极管和光伏组件。ISHTS 的性能与几种最先进的 PVPE 方法进行了广泛比较。仿真结果表明,ISHTS 的均方根误差(RSME)低至 10^{-4} 的 9.8602 倍、10^{-4}的 9.8248 倍、10^{-4}的 9.8248 倍和 10^{-4} 的 2.对于四种不同的光伏模型,分别得到了小至(8.88 倍 10^{-17})、(2.05 倍 10^{-6})、(1.88 倍 10^{-5})和(3.40 倍 10^{-17})的标准偏差(SD)。根据仿真结果,ISHTS 在各种 PVPE 问题的求解精度、可靠性和收敛性方面都具有优势。

期刊介绍: he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered. In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
