摘 要:宁夏风和光资源丰富,风电和光伏发电发展并驾齐驱。建立了含新能源发电的电网年度时序生产模拟仿真模型,以电网节能减排效益最大为目标,综合考虑了风光出力特性、负荷特性、机组调峰特性、不同种类供热机组热电耦合特性等因素。在建立模型的基础上,仿真研究了2015年宁夏电网新能源发电接纳能力,得到了综合考虑新能源限电率和电网节能减排效益的风光优化配比。该结果可为地区风电和光伏发电建设、电力系统调度以及政府相关政策制定提供指导。Ningxia's wind power and PV power both developed rapidly these years. The grid annual time sequence production simulation model containing renewable energy is established, whose target is to maximize energy conservation and emissions reduction benefits, the model considers wind and PV output, load characteristic, unit peak load regulation characteristic and thermal electricity couple characteristic of different heating units. Based on the model, Ningxia power grid renewable energy accommodation capability in 2015 is simulated, and optimized proportion of wind power and PV power considering renewable energy curtailment ratio and energy conservation and emissions reduction benefits is gained. The results provide guidance to the construction of wind and PV power, power system dispatching and policy making.
