【摘要】：在讨论高穿透功率风电对现代电力系统构成的并网技术挑战的基础上,提出并建立了基于储能技术的高穿透功率风电并网运行的条件建设补偿成本的概念和计算模型,研究了基于储能技术补偿风电功率预报误差、抑制风电反调峰和宽幅波动后的风电备用容量的惩罚成本,包括风电备用的容量成本和电量成本的计算方法和模型,建立了电网弃风运行的补偿成本计算模型;分析了大规模风电并网发电对现代电力市场及其产业政策的影响,提出并建立了反映电力发展求的风电运行成本计算模型;后,建立了高穿透功率风电广义运行成本计算模型。通过算例仿真进步讨论了:风电穿透功率较高时不宜将风电当成负值负荷计算风电备用容量,风电功率预报误差和风电场装机容量等因素对风电备用容量的电量成本和广义运行成本有较大的影响。
[Abstract]:On the basis of discussing the technical challenge of high penetrating power wind power to modern power system, the concept and calculation model of conditional construction compensation cost of high penetrating power wind power grid operation based on energy storage technology are put forward and established. The calculation methods and models of wind power reserve capacity, including the capacity cost and power cost of wind power reserve, are studied, which are based on energy storage technology to compensate for wind power power prediction error, and to suppress wind power reverse peak adjustment and wide fluctuation of wind power reserve capacity, including the calculation method and model of wind power reserve capacity cost. The calculation model of compensation cost is established, the influence of large-scale wind power generation on modern power market and its industrial policy is analyzed, and the calculation model of wind power operation cost reflecting the development of power is proposed. The generalized operating cost calculation model of high penetrating power wind power is established. Through the simulation, it is discussed that when the wind power penetration power is high, it is not appropriate to take wind power as negative load to calculate the reserve capacity of wind power. Factors such as wind power prediction error and wind farm installed capacity have great influence on the power cost and generalized operation cost of wind power reserve capacity.
