最近，光伏（PV）和电池存储（BS）技术成本的下降引起了人们对创建PV+BS混合发电厂的兴趣。混合电厂通过储存剪切能量来增加储能容量，同时还具有快速调度灵活性和电压安培无功支持的特点，从而扩大了电厂的电网服务。尽管许多拟建的光伏电站都采用并联电池，但公用事业规模的光伏+BS电站的主导架构尚不确定。此外，电源架构预计将根据未来趋势随着时间的推移而发展。本文的主要目标是严格检查和比较几种适合混合光伏+BS发电厂的dc-dc和dc-ac功率转换器架构。特别地，本文从功率半导体要求、效率、无功元件要求、模块化、控制复杂性等方面介绍了几种功率转换架构的特点。利用详细的分析模型，以及基准设计示例，对执行工程权衡研究的备选方案进行比较评估。
Recently, the falling costs of photovoltaic (PV) and battery storage (BS) technologies have raised interest in the creation of hybrid PV+BS power plants. Together with increasing energy storage capacity by storing clipped energy, hybrid plants broaden a power plant’s grid services by featuring fast dispatch flexibility and voltage-ampere reactive support. Although many proposed PV plants are being developed with colocated batteries, the dominant architecture of utility-scale PV+BS power plants is uncertain. Moreover, power architectures are expected to evolve over time based on future trends. The primary goal of this article is to critically examine and compare several dc–dc and dc–ac power converter architectures that are suitable candidates for hybrid PV+BS power plants. In particular, the article presents characteristics of several power conversion architectures from the point of view of power semiconductor requirements, efficiency, reactive component requirements, modularity, control complexity, and so forth. Detailed analytical models are utilized, along with a benchmark design example to present a comparative evaluation of the alternatives for performing engineering tradeoff studies.
