摘要

在太阳能的背景下,电网平价意味着光伏资源与更传统的电力资源具有竞争力。本文探讨了电网平价的各种概念,重点是电力电子方面。美国能源部公布的到2015年实现电网平价的目标意味着到2030年大规模转向太阳能。研究表明,太阳能系统的电力电子子系统需要大量的成本和可靠性改进来支持电网平价。逆变器需要匹配太阳能电池板典型的25年寿命,支持主要简化安装,并实现更低的制造成本。

Power Electronics Needs for Achieving Grid-Parity Solar Energy Costs
Grid parity in the context of solar energy implies that photovoltaic resources become competitive with more conventional electrical resources. The paper explores various concepts of grid parity, with emphasis on power electronics aspects. The published Department of Energy goal of grid parity by 2015 implies large-scale shifts to solar energy by 2030. It IS shown that the power electronics subsystems of solar energy systems require substantial cost and reliability improvements to support grid parity. Inverters need to match the typical 25-year life of solar panels, support major simplifications to installation, and achieve lower manufacturing costs.
