4MMC-MTDC直流电网多重主站直流电压协调控制策略研究(英文)显示文摘研究目前多端直流电网(multi-terminal DC,MTDC)的控制策略,提出一种新的基于下垂控制(droop control)的多端直流电压控制策略,可保证在一个控制直流电压的主站停运下直流电网的可靠性及电压稳定性。为验证所提出的控制策略的正确性和有效性,在RT-lab实时仿真器中建立一个五端(站)直流电网模型,远距离海岸风场通过直流电网与陆上交流系统连接起来。每一个站都由模块化多电平换流器(modular multilevel converter,MMC)组成,其中:两个换流器的控制方式是定直流电压和定无功功率控制(主站),两个换流站是定有功功率和无功功率控制(有差调节)、一个换流站是定交流电压和频率控制(风电场站)。当一个主站换流器停运时,仿真结果证实了所提出的新型直流电压控制策略的正确性和有效性。林畅 吴学光 Claudia E.Spallarossa Tim C.Green 2014智能电网2014,2,10:2
5Improved estimation of PM_(2.5) brown carbon contributions to filter light attenuation显示文摘Multiwavelength light attenuation measurements have been acquired as part of thermal/optical carbon analysis in the U.S.Chemical Speciation Network(CSN)and the Interagency Monitoring of PROtected Visual Environments(IMPROVE)network beginning in 2016.These are used to estimate PM_(2.5)brown carbon(BrC)contributions to light absorption at various wavelengths,a useful method for separating biomass burning contributions from other sources.Attenuation of light transmitted through the filter deviates from Beers Law as the mass of light absorbing materials increase.This study estimates the effects of these deviations with empirical adjustment factors applied to samples for CSN from 2016 to 2017 and for IMPROVE from 2016 to 2019.Accounting for the filter loading effect results in an annual average increase of∼6-7%BrC contribution to light attenuation:from 3.6%to 10.7%for the urban,more heavily loaded CSN samples;and from 23.7%to 29.5%for the non-urban IMPROVE samples.An alternative method is examined for BrC and black carbon(BC)adjustments by calculating the AbsorptionÅngström Exponent(AAE)for BC(i.e.,AAE_(BC))based on the ratios of 635 nm/780 nm light attenuation rather than assuming AAE_(BC)of unity.These paired-wavelength calculations result in a median AAE_(BC)of 0.76 for CSN and 0.8 for IMPROVE,with the majority of samples(i.e.,91%of CSN and 70%of IMPROVE)showing AAE_(BC)<1.By assuming negligible contributions from BrC to AAE at longer wavelengths,the amount of light attenuation at shorter wavelengths(e.g.,405 nm)where BrC is dominant can be calculated.The paired-wavelength method applied to the filter loading adjusted data has a greater effect on urban(fresh)than on non-urban(aged)aerosols,resulting in a factor of two increase in annual averaged BrC light attenuation(from 10.7%to 21.6%)for CSN and by a factor of 1.11(from 29.5%to 32.7%)for IMPROVE samples.This result demonstrates the importance of particle loading and AAE correction on quantifying BrC light attenuation from multi-wavelength thermal/optical analysis.Judith C.Chow L.-W.Antony Chen Xiaoliang Wang Mark C.Green John G.Watson 2021Particuology2021,19,3:2

10Comparison of Cost-effective Distances for LFAC with HVAC and HVDC in Their Connections for Offshore and Remote Onshore Wind Energy显示文摘For a cost-effective connection of large-scale longdistance wind energy,a low frequency alternating current(LFAC)transmission scheme(16.7 Hz or 20 Hz)is proposed as an alternative to the conventional high voltage alternating current(HVAC)transmission scheme(50 Hz or 60 Hz)and the recently popular high voltage direct current(HVDC)transmission scheme(0 Hz).The technical feasibility of the LFAC system is demonstrated but the basis for identifying the distance ranges for which LFAC would be preferable to HVAC and HVDC are not established and the dependence of this range on factors,such as power transfer rating,voltage rating and cable/line type,is not investigated.This paper presents an in-depth analysis for the overall cost of LFAC system and then provides an extensive comparison with HVAC and HVDC,to explore the distance ranges over which LFAC is cost-effective over both HVAC and HVDC in connections of offshore and remote onshore wind energy.The results demonstrate that the LFAC system does possess ranges in the intermediate distance for which it is more cost-effective than both HVAC and HVDC,and its overall cost advantage is generally larger in the overhead line(OHL)connection of remote onshore wind energy than the cable connection of offshore wind energy.Xin Xiang Shiyuan Fan Yunjie Gu Wenlong Ming Jianzhong Wu Wuhua Li Xiangning He Timothy C.Green 2021CSEE Journal of Power and Energy Systems2021,7,5:1
