摘要
文章在分析光伏电站的有功出力对其无功电压和有功损耗影响的基础上,综合考虑光伏逆变器和SVG的无功调节能力,提出一种基于光伏电站有功出力的无功优化控制策略。以光伏电站内部电压偏差最小和有功损耗最小为优化目标建立多目标优化模型,运用模糊理论将其处理为单目标优化模型,最后采用差分进化算法进行求解。经算例仿真,验证了所提策略的可行性和优越性。
Based on the analysis of the effect of photovoltaic power plant's active output on its reactive voltage and active loss,the paper comprehensively considers the reactive power adjustment ability of photovoltaic inverter and SVG,and proposes a reactive power optimization control strategy based on the active output of photovoltaic power plant.The multi-objective optimization model is established with the minimum internal voltage deviation and the minimum active loss of the photovoltaic power station.The fuzzy theory is used to process it into a single-objective optimization model.Finally,the differential evolution algorithm is used to solve the problem.The feasibility and superiority of the proposed strategy are verified by simulation.
