摘要
能源紧缺和环境治理是当今世界急需解决的一大问题,在实现最大能源使用效率的条件下进行可持续发展是我国一直追求的目标,其中风光互补分布式发电站是我国目前主要的一种分布式能源电站。光能具有广泛性、稳定性、高效利用性,成为了目前最广泛使用的新能源之一,风能也具有广泛性,但与光能相比其稳定性与高效利用性较差。为了充分利用光能与风能,设计了一个以光伏发电为主要发电系统、风力发电作为辅助发电系统的风光互补发电储能系统。根据设计指标与光伏系统设计原理,首先设计了光伏系统中的最大追光(MPPT)模块与储能系统的双向DC-DC模块,对设计的模块在Simulink环境下进行了仿真验证,达到了最大功率跟踪以及光、储能互补的要求,接下来设计了风力发电系统的控制策略,达到了风力发电系统作为辅助发电系统的要求,最后对光伏系统以及整个系统进行了实验室验证。
Energy shortage and environmental governance are problems that need to be solved urgently in the world today.Sustainable development under the condition of maximum energy efficiency has always been the goal pursued by China,and wind-solar complementary distributed power station is the main distributed energy power station in China at present.Light energy with universality,stability and high efficiency has become one of the most widely used new energy at present.Wind energy is also widespread,but is less stable and efficient than light energy.In order to make full use of solar energy and wind energy,this paper designs a wind-solar complementary power generation storage system with photovoltaic as the main power generation system and wind power as the auxiliary power generation system.According to the design index and photovoltaic system design principle,first are designed the Maximum Power Point Tracking(MPPT)module of the photovoltaic system and the bidirectional DCDC module of the energy storage system,and then is made simulation and verification on the designed module in Simulink environment,which meets the requirements of maximum power tracking and complementary optical and energy storage.And next is designed the control strategy of wind power generation system,which satisfies the requirements of wind power generation system as an auxiliary power generation system.Finally,the photovoltaic system and the whole system were validated in the laboratory.
