A Standalone MicroSolar Electrical Energy Production and Conversion System

该项目旨在产生电力电子、优化和控制领域的新知识和先进技术，可用于开发额定功率高达1千瓦的创新型独立微型太阳能转换系统，该系统由三个主要子系统组成：光伏（PV）系统、电池储能系统（BESS）和用于为负载供电的电源转换系统。拟议项目的预期结果将为充电站提供几个先进的功能，包括最大的光伏电力收集算法，延长电池寿命的最佳电池充电器，具有成本效益和可扩展的系统设计，故障诊断和保护系统，以及先进的防盗系统。为了最大限度地获得光伏发电，光伏板将使用先进的机电一体化太阳能跟踪系统跟踪最大太阳辐照。此外，将开发一种结合线性和非线性MPPT方法的最大功率点跟踪（MPPT）算法，以便在不受天气条件影响的情况下准确跟踪最大功率点。在BESS中，将引入一种低成本和最佳的电池充电器，通过最小化电池组阻抗来提高充电效率并延长电池寿命。整个系统的可扩展性将通过一个集中的数据库进行管理，所有子系统的状态将存储在该数据库中。子系统将通过使用由该项目的工业合作伙伴Alizeti开发的快速可靠的通信协议访问数据库，以更新整个系统状态。因此，该项目将为偏远原住民地区和不发达国家的太阳能电动自行车充电站、学校和社区中心提供可持续的低成本能源。

This project aims to generate new knowledge and advanced technologies in the domain ofpower electronics, optimization and control that can be used to develop an innovative standalone micro-solar energy conversion system with a power rating up to 1 kW, which consists of three main subsystems: a photovoltaic (PV) system, a battery energy storage system (BESS), and a power conversion system for powering loads. The expected results of the proposed project will provide several advanced features to the charging station including a maximum PV power-harvesting algorithm, an optimal battery charger to prolong battery lifetime, a cost-effective and scalable system design, a fault diagnosis and protection system, and an advanced anti-thief system. In order to maximize the harvest PV power, the PVpanels will track the maximum sun irradiation using an advanced mechatronics solar tracker system. In addition, a maximum power point tracking (MPPT) algorithm combining linear and nonlinear MPPTmethods will be developed to track accurately the maximum power point regardless of weatherconditions. In the BESS, a low-cost and optimal battery charger will be introduced to increase thecharging efficiency and improve the battery lifetime by minimizing the battery pack impedance. Thescalability of the overall system will be managed through a centralized database, where the status of allsubsystems will be stored. The subsystems will access the database to update the overall systemstatus by using a fast and reliable communication protocol developed by Alizeti, the industrial partner inthis project. As a result, this project will contribute to provide a sustainable low-cost power source that can beused for powering solar electric-bike charging stations, schools and community centers in remote aboriginalareas and underdeveloped countries.
