计及多约束条件的风光互补容量配比研究

为了提高可再生能源利用效率以及土地资源利用率，研究了风电和光伏同场互补共建的容量匹配问题。分析影响光伏增建容量的相关因素，在此基础上建立了反映风电与光伏同场共建互补发电效益与相关约束的指标，并给出增建光伏容量的计算方法及流程。所提方法计及了风光互补发电特性、功率外送限制等运行约束，同时也考虑了光照强度、已建风场设施遮挡阴影等因素对增建光伏容量的影响，方法具有较强的工程实用性。以甘肃某实际风场为例，运用Sunlight和PVsyst仿真软件进行测算，并对风电光伏同场发电的经济效益和相关指标进行分析。仿真结果验证了所提配置方法的合理性和实用性。

Research on complementary capacity ratio of wind power and photovoltaic considering multiple constraints

Taking matching capacity of constructing photovoltaic power plant in a wind farm as research target could improve the utilization of land resources and increase the connection capacity of renewable energy. Indicators for reflecting generation benefit of wind power and photovoltaic power in the same field and relevant constraints are formulated by analyzing related factors about increasing photovoltaic power capacity. Calculation method and process of building solar power station are made. The proposed method contains operating constraints about wind and solar power generation characteristics and power delivery restriction. The method which has a strong engineering practicality considers effect of light intensity and shadow of facilities on PV arrays. Taking a real wind farm in Gansu province, making estimation by using Sunlight and PVsyst software can analyze relevant indicators and wind and PV power generation benefit. Rationality and practicability of the configuration proposed will be confirmed by simulation results.
