【摘要】：为准确评估区域电力系统风电接纳能力,针对目前风电规划问题,给出一种新的计算方法。以整个时间区间上系统接纳风电电量和系统火电机组发电电量为规划指标,改变了传统风电规划主要着眼于最严峻条件下系统最大风电接纳容量的规划方法。在实际计算过程中,将系统接纳风电电量计算分两步实现,简化了模型求解过程。通过遗传算法得到任意时间区间上的系统投运机组组合,从而分析系统机组调峰能力极限。此外,将系统负荷与系统机组出力视为能量供需双方,在每个时序点上达到供需平衡,结合风资源信息计算系统可接纳风电电量及火电机组发电电量。根据实际区域电网负荷数据以及发电机组数据,经仿真计算表明,该规划方法能准确评估区域电力系统风电接纳水平,为风电装机规划提供技术参考。
[Abstract]:In order to accurately evaluate the wind power acceptance capacity of regional power system, a new calculation method is proposed for the current wind power planning problem. Taking the system acceptance of wind power and the generating capacity of thermal power unit as the planning index in the whole time interval, the traditional wind power planning method which mainly focuses on the maximum wind power acceptance capacity under the most severe conditions is changed. In the process of practical calculation, the calculation of system accepting wind power is realized in two steps, which simplifies the process of solving the model. Through genetic algorithm, the system operation unit combination in any time interval is obtained, and the peak shaving ability limit of the system unit is analyzed. In addition, the system load and unit output are regarded as both sides of energy supply and demand, and the balance of supply and demand is reached at each time series point, and the system can accept wind power and thermal power generation with wind resource information. According to the actual load data and generator data, the simulation results show that the planning method can accurately evaluate the wind power acceptance level of the regional power system, and provide a technical reference for wind power installation planning.
