中文摘要：

随着潮流能发电技术日趋成熟,大规模的潮流能发电系统将并网运行。潮流能发电系统的输出功率每天随时间在零和最大功率之间变化,这对电网的调峰能力提出了新的挑战。文章基于非序贯蒙特卡洛模拟方法,通过计算调峰不足概率指标对大规模潮流能并入电网条件下的电网调峰充裕度进行评估,研究潮流能极限接入功率,并与风电接入后系统的调峰充裕性进行比较,由于潮流能的可预测性,潮流能的接入对系统调峰充裕度的影响远远小于风力发电。通过对IEEE-RTS32机测试系统进行仿真分析,验证了所提方法的可行性和有效性。

英文摘要：

As the tidal energy technology has become increasingly mature, predictably, in the near future, large-scale tidal current generation systems will be integrated into the power grid. The peak-load regulation capacity of the grid will be confronted with new challenges on account of the time-dependent nature tidal energy. In this study, the peak load regulation adequacy in power system with large-scale tidal current energy penetration was assessed based on non-sequential Monte-Carlo simulation method.The peak load regulation margin information was obtained by means of calculating peak-load regulation not enough probability（PRNEP） index so as to determine the appropriate tidal current energy integrated to the grid.Compared with wind power, the influence on peak-load regulation adequacy in power grid with tidal power penetration is far less than wind power generation owing to the predictability of tidal current energy. The simulation on IEEE-RTS32 system demonstrates that the proposed method is feasible and effective.
