Abstract

This article proposes an innovative application of the Catch Fish Optimization method (CFOA) to effectively handle the complex Probabilistic Optimal Power Flow (POPF) optimization problem in modern power grids. The growing penetration of stochastic renewable energy sources, photovoltaic (PV) and wind energy, plus the presence of geothermal generation, causes uncertainties. The classical Optimal Power Flow (OPF) can’t address such uncertainties. This paper introduces the capabilities of the CFOA in addressing such uncertainties. The target is to determine optimal design variables considering the probabilistic models of generation. The introduced algorithm has been investigated on IEEE 30- and 118-bus networks. Moreover, these systems are modified to include PV, wind, and geothermal units. Both fixed and dynamic load profiles are included in the study. The simulation results for the 30-bus system show a reduction in total daily fuel costs of approximately 9.64% when compared with the no-renewables baseline. For the larger 118-bus system, the daily fuel cost reduction was even more significant, at approximately 15.91%. The results obtained using the CFOA are compared with those from other well-established algorithms. The comparative analysis confirms the greater CFOA performance in terms of the convergence speed besides the robustness. This analysis affirms the effectiveness of the introduced optimization techniques in tackling the POPF problem. The current research paves the way for further investigation into the application and enhancement of the CFOA for various power system optimization problems.
地热发电厂等可再生能源不确定电力系统的最优潮流
本文提出了一种创新的Catch - Fish优化方法(CFOA),以有效处理现代电网中复杂的概率最优潮流(POPF)优化问题。随机可再生能源,光伏(PV)和风能的日益普及,加上地热发电的存在,造成了不确定性。经典的最优潮流(OPF)算法无法解决这种不确定性。本文介绍了CFOA在处理此类不确定性方面的能力。目标是考虑发电的概率模型,确定最优的设计变量。所介绍的算法已经在IEEE 30和118总线网络上进行了研究。此外,这些系统被修改为包括光伏、风能和地热装置。研究中包括了固定载荷和动态载荷。模拟结果显示,与无可再生能源基线相比,30辆公交系统的每日总燃料成本降低了约9.64%。对于更大的118总线系统,每日燃油成本降低幅度更大,约为15.91%。用CFOA得到的结果与其他已建立的算法的结果进行了比较。对比分析表明,除了鲁棒性外,CFOA算法在收敛速度上也有较好的表现。这一分析证实了所引入的优化技术在解决POPF问题上的有效性。本研究为进一步研究CFOA在各种电力系统优化问题中的应用和增强奠定了基础。
