计及绿色能源出力不确定性的输电网线损率概率评估

针对目前输电网线损率评估方法不能满足节能降耗的需要,提出了计及绿色能源出力不确定性的输电网线损率概率评估方法。该方法包括系统状态模拟与蒙特卡罗抽样两部分。系统状态模拟包括绿色能源出力的模拟、负荷状态的模拟、机组日节能调度以及网络安全校正控制的模拟、厂站电压无功控制的模拟。在蒙特卡罗随机抽样时,基于上述系统状态模拟方法,通过对随机样本的状态调整与潮流计算确定输电网线损率的概率分布。最后,以某省级电网为例,验证了所提线损率概率评估方法的有效性。

区块链技术及渠道权力对绿色供应链决策影响

文章基于制造商主导、零售商主导和无主导的三种供应链权力结构,采用博弈论方法定量研究了由单一制造商和单一零售商组成的竞争型绿色供应链决策问题。研究发现:在一定条件下,消费者绿色不确定性越大反而越能激励制造商提高产品绿色度,并提高供应链绩效;区块链接受度越高不一定越好,而是使得产品绿色度和供应链利润先减后增;区块链赋能的产品价格总比未采用区块链的产品价格更低,在区块链接受度或绿色不确定性偏高时,区块链应用对消费者有益;此外,制造商主导时产品绿色度最高,而无主导时供应链利润最高且对消费者最有利。

Current Status of Green Financing in Korea and Political Implications

This research shows the current status and the future prospects of green financing in Korea. Green financing is currently on the initial stage in Korea, just like the green growth policy. Thus, banks are contextually not willing to invest or loan in the green technology or industry for profitability, because the high uncertainty （risk） exists and because Korean people have little concern on green financing, though they have recognized the necessity of green growth. Therefore, the reinforcement of government＇s role is suggested in this research. The public financial agencies are now very important in popularizing the green financing in Korea, and the most effective policy will be the credit guarantee for green technologies or companies provided by public agencies, as shown in the financing policy for the small and middle enterprises. Regarding public efforts, banks should try to perform green financing for both their own profitability and social benefit together with the step-by-step approach, according to the growth stage of green industry and green financing.
