负荷差值特性曲线法在分布式光伏消纳方案中的应用
|
摘要
研究创新地提出负荷差值特性曲线法动态评估区域光伏发电与用电负荷之间关系。引入时间轴,动态分析区域光伏出力特性以及用电负荷特性,利用历史数据采用回归分析拟合数学模型,根据就地消纳原则,分析两条曲线差值变化规律,得到区域现有负荷水平下光伏建设最大规模。考虑光伏分散布置对降低网损与增加造价的影响程度,确定最优光伏配置方案。针对实际案例,通过编程计算、大方软件建模,得出当地最大光伏建设规模以及最优配置方案。该方法较好地指导了电网分布式光伏规划建设。
A innovative load D-Value characteristic curve method is proposed to dynamically evaluate the relationship between regional PV generation and electric load.The regional characteristics of PV generation and electric load is dynamically analyzed in the time axis,use the regression mathematical model to fit the mathematical model based on historical data,analyse the D-Value regular of the two curves according to local consumption principle,get the local maximun construction scale of PV generation in the existing load level.Considering the effective of PV cut-up arrangement on reducing network loss and increasing investment,to fix the best configuration of PV power.In view of the case,the local most scale of PV construction and the optimal allocation scheme are obtained through programming calculation and generous software modeling.The method is a good guide for the distributed PV planning of power grid.
