摘要
根据风能和太阳能在时间和地域上的天然互补性,综合考虑常规机组的强迫停运,在夏冬季典型日下计算风光互补性在季节和昼夜两方面对于系统充裕度的影响。定义新能源有效带载能力(N-ELCC)描述含新能源的发电系统的负荷承载能力,并给出N-ELCC随风光容量比例的变化特性,以及N-ELCC对静态备用容量的影响。算例表明,系统的充裕度及可靠性随风光投入容量比例、季节以及昼夜更替而变化。最后给出算例地区气候环境所适宜的科学新能源发电建议,并可以在保证可靠性满足要求的前提下,减少备用投资,提高其经济性。
According to the natural complementarity of wind and solar energy in time and geography, the influences of wind-PV complementary on the system adequacy are Calculated in typical summer and winter days while the forced outage of conventional generating units is also considered. The influences are presented in two aspects： seasonal and diurnal. A new energy effective load carrying capacity （N-ELCC） is defined to describe the load carrying capacity of the generating system containing new energy. Variability of N-ELCC from the changes of the wind-PV capacity ratio is analyzed, as well as the effects of N-ELCC on the static reserve capacity. Results show that system adequacy and reliability vary with the wind-PV capacity ratio, the altemation of day and night as well as seasons. Finally, a new energy power generation proposal is proposed scientifically considering the regional climate and environment of the case. The proposal can reduce the reserve investment and improve the economy on the premise of the assurance of reliability.
