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 kW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)和为负载供电的电力转换系统。拟议项目的预期结果将为充电站提供几个先进的功能，包括最大限度的光伏发电收集算法、延长电池寿命的最佳电池充电器、经济高效且可扩展的系统设计、故障诊断和保护系统以及先进的防盗系统。为了最大限度地获取光伏发电，PVPanel将使用先进的机电一体化太阳能跟踪系统来跟踪最大太阳辐射。此外，还将开发一种结合线性和非线性最大功率点跟踪(MPPT)方法的算法，以精确跟踪最大功率点，而不受天气条件的影响。在BESS中，将引入一个低成本和优化的电池充电器，通过最小化电池组阻抗来提高充电效率和延长电池寿命。整个系统的可升级性将通过一个中央数据库进行管理，其中将存储所有子系统的状态。这些子系统将使用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，该项目将有助于提供一种可持续的低成本电源，用于为偏远土著地区和欠发达国家的太阳能电动自行车充电站、学校和社区中心供电。

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.
