Abstract

This paper proposes optimisation techniques for the operations of cloud electric vehicle-to-grid battery (CEVB) in microgrids with high penetration of solar photovoltaics (PVs). It thoroughly scrutinises popular methods such as gradient descent (GD), as well as three heuristic methods, including pattern search (PS), particle swarm optimisation, and genetic algorithms. Addressing the limitations of these methods, such as local optimality and constraint violations, is achieved through intensive experimentation, utilising stochastic initialisation and a hybrid heuristic-GD multiple-run strategy. These experiments also investigate the effects of heuristic algorithm parameter settings on the optimisation results, identify optimal parameters for each heuristic-GD method, and assess their effectiveness in handling uncertainties in CEVB operational model inputs (solar irradiance, electricity price, and electric vehicle [EV] power demand). Evaluations conducted using actual operational data from an EV charging station in South Australia demonstrate that all proposed methods can achieve global optimal results in fewer than 100 runs with appropriate parameter settings. Scalability tests were conducted to validate the method's feasibility for larger systems, offering valuable insights into computation times as the number of CEVBs grows. The proposed methods demonstrate robustness in addressing uncertainties in electricity prices and EV power demand, ensuring reliable and adaptable performance across various scenarios.

太阳能光伏高渗透率微电网云电动车并网电池运行优化算法比较研究
本文提出了在太阳能光伏发电(pv)渗透率高的微电网中云电动汽车到电网电池(CEVB)运行的优化技术。它彻底审查了流行的方法,如梯度下降(GD),以及三种启发式方法,包括模式搜索(PS),粒子群优化和遗传算法。解决这些方法的局限性,如局部最优性和约束违反,是通过密集的实验,利用随机初始化和混合启发式- gd多运行策略实现的。这些实验还研究了启发式算法参数设置对优化结果的影响,确定了每种启发式- gd方法的最优参数,并评估了它们在处理CEVB运行模型输入(太阳辐照度、电价和电动汽车[EV]电力需求)不确定性方面的有效性。利用南澳大利亚电动汽车充电站的实际运行数据进行的评估表明,在适当的参数设置下,所有提出的方法都可以在不到100次的运行中获得全局最优结果。进行了可伸缩性测试,以验证该方法在大型系统中的可行性,随着cevb数量的增加,对计算时间提供了有价值的见解。所提出的方法在解决电价和电动汽车电力需求的不确定性方面具有鲁棒性,确保了各种场景下的可靠和适应性性能。

期刊介绍: IET Renewable Power Generation (RPG) brings together the topics of renewable energy technology, power generation and systems integration, with techno-economic issues. All renewable energy generation technologies are within the scope of the journal. Specific technology areas covered by the journal include: Wind power technology and systems Photovoltaics Solar thermal power generation Geothermal energy Fuel cells Wave power Marine current energy Biomass conversion and power generation What differentiates RPG from technology specific journals is a concern with power generation and how the characteristics of the different renewable sources affect electrical power conversion, including power electronic design, integration in to power systems, and techno-economic issues. Other technologies that have a direct role in sustainable power generation such as fuel cells and energy storage are also covered, as are system control approaches such as demand side management, which facilitate the integration of renewable sources into power systems, both large and small. The journal provides a forum for the presentation of new research, development and applications of renewable power generation. Demonstrations and experimentally based research are particularly valued, and modelling studies should as far as possible be validated so as to give confidence that the models are representative of real-world behavior. Research that explores issues where the characteristics of the renewable energy source and their control impact on the power conversion is welcome. Papers covering the wider areas of power system control and operation, including scheduling and protection that are central to the challenge of renewable power integration are particularly encouraged. The journal is technology focused covering design, demonstration, modelling and analysis, but papers covering techno-economic issues are also of interest. Papers presenting new modelling and theory are welcome but this must be relevant to real power systems and power generation. Most papers are expected to include significant novelty of approach or application that has general applicability, and where appropriate include experimental results. Critical reviews of relevant topics are also invited and these would be expected to be comprehensive and fully referenced. Current Special Issue.
