摘要

可再生能源的渗透和自主电力系统的发展,为孤立的消费者提供了诸如覆盖灯塔、小岛屿、修道院甚至孤立的特殊工业设施的能源需求等应用。电厂成本是制约这些系统发展的主要因素。例如,虽然近年来光伏电站的机电成本已经明显降低,但没有考虑土地成本,这是一笔很大的支出。本文以Attica Stachtorroi岛岸线电极变电站供电的自主电站设计为实际问题进行了研究。电极变电站是Attica-Crete高压直流(HVDC)电力互联项目的一部分。针对上述问题,本文提出了一种光伏电站的整体评价算法,该算法考虑了电站的技术特点、安装和运行成本(除电厂各部件的机电成本和效率外,还包括土地成本)以及各公司各个关键部件(光伏板、逆变器)的实际商业数据。通过穷举搜索,根据电力需求和减资利率选择最优系统

An Optimal Design of a Small Photovoltaic Plant with Cost Minimization based on a Real Database of PV Panels and Inverters
The penetration of renewable energy sources and the development of autonomous power systems for the supply of isolated consumers find applications such as covering energy needs in lighthouses, small islands, monasteries, and even isolated special industrial facilities. Power plant cost is a major limitation in the development of these systems. For example, although the electromechanical cost of photovoltaic plants has been significantly reduced in recent years, however the land cost is not considered, which is a significant expenditure. In this paper, the real problem of an autonomous power station design for the supply of the shoreline electrode substation on the Stachtorroi islet of Attica, is taken as the starting point. The electrode substation is part of the Attica-Crete high voltage direct current (HVDC) electrical interconnection project. For the above problem, an overall evaluation algorithm for a photovoltaic (PV) plant is proposed that considers the technical characteristics of the plant, the installation and operating costs (including land costs in addition to electromechanical costs and efficiency of each of the plants components), as well as the actual commercial data of the individual key elements (PV panels, inverters) of various companies, choosing the optimal system through exhaustive search depending on the required power and the deflated capital reduction interest rate
