独立式风光互补发电系统中最大功率控制策略研究

独立风光互补发电系统从能量的角度来看可以分为3部分，即能量获取部分，能量存储部分以及能量消耗部分。主要介绍了能量获取所涉及的风力机最大功率运行和光伏电池最大功率跟踪这2个问题的控制策略，同时对能量存储部分所涉及的蓄电池充放电的控制策略进行了介绍，其中对充电策略的三阶段法做了比较详细的分析。最后对最大功率控制策略的研究方法作了系统的评述并对该领域今后的研究方向作了展望。

Overview of Maximum Power Control Strategies in Stand-Alone Wind and Solar Hybrid Generation Systems

A Stand-alone wind/solar hybrid generation system can be divided into three parts from the perspective energy: energy getting, energy storage and energy consumption. In the hybrid generation system, these three parts correspond with the wind turbines and photovoltaic arrays, batteries and energy-consuming load, respectively. The energy getting part transforms the wind and solar power into electric power, while the energy storage part regulates energy and balances load. This paper introduced control strategies for the maximum power operation of wind machines and maximum power point tracking of solar photovoltaic battery in the energy getting part, as well as batteries charge and discharge control strategies in the energy consumption part with a detailed analysis made on the 3-stage of the charge strategies. At last, a systematical overview was made on the research method for the maximum power control strategies and an outlook on the direction for future researches in this area was presented.
