1.  エネルギー政策調査
電力、都市のモビリティ、空間計画の3つのセクターには、金融、税制、貿易政策、イノベーション、
適応策など、脱炭素化のための多くの政策の不整合が残されています。私たちは、国際・国内の政策レビューや各種モデル分析を実施することで、新技術の規制を調整し、脱炭素化を加速させることを提案します。

Development of community microgrid in urban residential area: Case study of Ulaanbaatar, Mongolia

Tumurbaatar Uyanga, Energy Course M2 student, IGPC (March 2022, Graduate)

Electrical power microgrids (see fig.) have been mainly seen as a solution for rural electrification integrating more renewable energy, and offering reliable power supply, however, in recent years, it’s getting more attention in urban areas as well. Especially, in cities in developing country, various issues are entangled with energy issue, such as energy security, diversification, environmental and social problems etc. In this research, the microgrid development will be studied as an alternative solution to tackle various issues in Ulaanbaatar, Mongolia.

Having rich renewable energy resource, Mongolian energy system is heavily dependent coal which causes

deadly air pollution yet imports 20% of electricity demand from Russia. Also, both the generation and

transmission facility are exceeded their lifespan, thus requiring system upgrade in near future, to supply

reliable, sustainable, and affordable electricity and heat to its increasing population. Through this research,

the appropriate technology combination suited for local demand characteristics will be evaluated using

Homer Pro software simulation and will be compared to previous projects done by the government in terms

of economic and environmental impact. See fig. below source: Microgrid, Source: Enova Energy

A multi-energy complementary microgrid superstructure model by improving the integration of renewable energy:Case study of Northern China

 

Hu Dongzi, M1 student, IGP(C) Energy course

Nowadays Northern China still mainly depends on fossil fuels to generate electricity while the use of renewable energy is relatively low portion of the energy mix. Therefore, with an increasing population their is greater need for electricity puts huge pressure on the local environment. The Chinese government is making a great effort to solve environmental pollution and energy shortage. In Northern China, the potential for increasing renewable energy is huge so that Smart microgird can be regarded as the alternative solution to use renewable energy as much as possible to alleviate serious environmental problems.
 
Through this research, the optimal smart microgrid configuration and size for the case would be worked out by using python. More renewable energy would be integrated to supply reliable, economical and environmental-friendly electricity. Peer-to-peer energy trading system(see fig. Below) is the power control and operation way that would be used in the research. Distributed energy resources are traded among local consumers and prosumers. It means user can decide whom they purchase electricity and whom they sold electricity out. P2P energy trading would be backed up by blockchain that enables consumers to trade energy safely,directly and economically.
